Abstract

The 2011 Population and Housing Census of Samoa was taken on the midnight of November the 7th 2011. It counted every person in the country on that night and collected a wide range of social, economic and demographic information about each individual and their housing status.

The information were used to develop statistical indicators to support national plannning and policy-making and also to monitor MDG indicators and all other related conventions. This included population growth rates, educational attainment, employment rates, fertility rates, mortality rates, internal movements, household access to water supply, electricity, sanitation, and many other information. The full report is available at SBS website: http://www.sbs.gov.ws under the section on Population statistics and demography.

Users' consultation seminars were conducted for three consecutive days (June 8th -10th, 2010) with financial support provided by the office of UNFPA in Suva via the Samoa Parliamentary Group for Population Development (SPGPD) annual programs. For the first time in census history, the SPGPD or members of parliament have become the target group of users to get involved in any census questionnaire consultations.

All government ministries and non-governmental organizations were invited to the consultation seminars and each was asked to make a presentation of data needs for consideration in the final census 2011 questionnaire. To avoid re-inventing the wheel in the compilation of the list of census questions for census 2011, the questionnaire from the census 2006 was reprinted and distributed to all participants and presenters to select questions that they would consider again for the census 2011 in addition to their new data needs. Users were also advised that any new question would need good justifications of how it links to national interests.

At the end of the three days seminar, all new questions were compiled for final selection by Samoa Bureau of Statistics. Not all the users' data needs have been included in the final 2011 census questionnaire due mainly to the cost involved and limited time for census enumeration. Therefore, the final selection of questions was purely based on the linkage of the data being requested to the list of statistical indicators in the 'Strategy for the Development of Samoa 2008-2012' (SDS) and the 'Millennium Development Goals' (MDGs) 2015. All data requests outside of the two frameworks were put aside to be integrated in other more appropriate survey activities by the bureau.

From July 2010-December 2010, the questionnaire was formatted using the In-Design CS4 software. It is important to note that the PHC 2011 was the first ever census using the scanning technology to process data from the census questionnaires as a replacement of the usual manual data entry process. The scanning was pilot tested in April 2011, before it was finally used for final census enumeration.

The questionnaire was designed using A3 paper size.

The Population questionnaire was administered in each household, which collected various information on household members including age, sex, citizenship, disability, orphanhood, marital status, residence (birth, usual, previous), religion, education and employment.

In the Population questionnaire, a special section was administered in each household for women age 15-49, which also asked information on their children ever born still living, died or living somewhere else. Mothers of children under one year were also asked whether their last born children were still living at the time of the census.

The Housing questionnaire was also administered in each household which collected information on the types of building the household lived, floor materials, wall materials, roof materials, land tenure, house tenure, water supply, drinking water, lighting, cooking fuel, toilet facility, telephone, computer, internet, refrigerator, radio, television and others.

Sampling error estimates

The census is a full-coverage of the population, therefore it is not a sample where sampling errors can be estimated.

Data appraisal

There was no post-enumeration in the census 2011. One of the normal practices by the bureau to validate the total population counts from all villages, districts and regions of Samoa in any census is the manual count of the population in all areas during the on-going census enumeration.That information is collected by the enumerators and field supervisors during the enumeration using the Enumerators and Supervisors control forms. At the end of the enumeration, the control forms which mainly contained the number of males and females per enumeration area will be collected and compiled by the Census and Survey division as the first preliminary count of the census. In the census 2011, the preliminary population counts were compiled and launched as the 'Village Directory 2011' report after 4 weeks from end of the enumeration period.

The significance of the Village Directory report is it helps to provide a qiuick overall picture of the population growth and population distribution in all villages of the country relative to previous censuses. Most important of all is that the preliminary count will provide the basis for a decision whether a post-enumeration is warrant or otherwise. If the preliminary country is close to the projected population then the post-enumeration is assumed not worth the cost because it is expensive and it will delay all other census processes. In the census 2011, the preliminary count arrived at 186,340 which was more than the projected population of 184,032 as depicted in the Statistical Abstract 2009. Therefore the decision was made that post-enumeration was not worth it.

Abstract

The Census provides a unique source of detailed demographic, social and economic data relating to the entire population at a single point in time. The most fundamental questions it will answer concern the size and distribution of the entire population, the extent to which men and women participate in the economy, and the nature of housing and household facilities.

Our country is constantly changing and information collected will allow policy planners to measure the developments of our society and to make decisions about future needs of our communities. Emphasis for the CPD is on renewable energy. Government has set itself policy goals that by 2015, 50 percent of Cook Islands electricity demand will be provided by renewable energy and 100 percent in 2020. Culture has also been identified as a priority of Government.

The topic content of the 2011 Census has been driven principally by the demands and requirements of users of census statistics, the evaluation of the 2006 Census, and the priorities of the Government as stated in its manifesto, and the advice and guidance of organisations with experience of similar operations. These have been determined by extensive consultations with various Ministries of government and non government organizations (NGO).

The topics proposed for the census are those most needed by the major users of census information and questions have been devised to produce reliable and accurate data. In each case, no other comparable and accessible source of the information is available in combination with other items in the census.

In assessing which topics should be included in the census, Statistics Office has had to consider a number of factors. The criteria for evaluating the strength of users' requirements for information were that:

· there should be a clearly demonstrated and significant need · the information collected was of major national importance · users' requirements could not adequately be met by information from other sources · there should be a requirement for multivariate analysis (that is the ability to cross-analyze one variable against other), and · there should be consideration of the ability for comparison with the 2006 Census wherever possible

The questionnaire of the early Cook Islands censuses was limited; they consisted oh head counts only. With the passage of time, the topics covered by the questionnaires expanded. Gradually, questions on sex, age, marital status, religion, education, employment, etc have been included. Questions on unpaid work and income earned were included for the first time in the 1996 Census. In the 2011 Census, questions on renewable energy and culture was included.

The questionnaire of the 2011 Census of Cook Islands is divided into 2 main forms: -Dwelling form: which covers topics like: Household characteristics, water supply, energy, toilet, tradition, communication & technology, waste management, involvment in agriculture, fishing, farming, equipment, transport. -Personal form: which covers topics like: Individual characteristics, disability, literacy and language, information & technology, education, economic activity, income, narcotics, cultural activities and fertility.

SELECTION OF TOPICS AND QUESTIONS: The topic content of the 2011 Census has been driven principally by the demands and requirements of users of census statistics, the evaluation of the 2006 Census, and the priority of government as stated in this Governments Manifesto, and the advice and guidance of organizations with experience of similar operations. These have been determined by extensive consultation with various Ministries of government and NGO's. Emphasis for this Census was on Renewable Energy and Cultural Statistics. Government had set itself a policy goal that 50 percent of its electricity demands to be provided by renewable energy in 2015 and 100 percent in 2020.

The 2011 Census questionnaire is designed to be machine readable that is questionnaires will be scanned.

Abstract

Censuses are principal means of collecting basic population and housing statistics required for social and economic development, policy interventions, their implementation and evaluation.The census plays an essential role in public administration. The results are used to ensure: • equity in distribution of government services • distributing and allocating government funds among various regions and districts for education and health services • delineating electoral districts at national and local levels, and • measuring the impact of industrial development, to name a few The census also provides the benchmark for all surveys conducted by the national statistical office. Without the sampling frame derived from the census, the national statistical system would face difficulties in providing reliable official statistics for use by government and the public. Census also provides information on small areas and population groups with minimum sampling errors. This is important, for example, in planning the location of a school or clinic. Census information is also invaluable for use in the private sector for activities such as business planning and market analyses. The information is used as a benchmark in research and analysis.

Census 2011 was the third democratic census to be conducted in South Africa. Census 2011 specific objectives included: - To provide statistics on population, demographic, social, economic and housing characteristics; - To provide a base for the selection of a new sampling frame; - To provide data at lowest geographical level; and - To provide a primary base for the mid-year projections.

About the Questionnaire : Much emphasis has been placed on the need for a population census to help government direct its development programmes, but less has been written about how the census questionnaire is compiled. The main focus of a population and housing census is to take stock and produce a total count of the population without omission or duplication. Another major focus is to be able to provide accurate demographic and socio-economic characteristics pertaining to each individual enumerated. Apart from individuals, the focus is on collecting accurate data on housing characteristics and services.A population and housing census provides data needed to facilitate informed decision-making as far as policy formulation and implementation are concerned, as well as to monitor and evaluate their programmes at the smallest area level possible. It is therefore important that Statistics South Africa collects statistical data that comply with the United Nations recommendations and other relevant stakeholder needs.

The United Nations underscores the following factors in determining the selection of topics to be investigated in population censuses: a) The needs of a broad range of data users in the country; b) Achievement of the maximum degree of international comparability, both within regions and on a worldwide basis; c) The probable willingness and ability of the public to give adequate information on the topics; and d) The total national resources available for conducting a census.

In addition, the UN stipulates that census-takers should avoid collecting information that is no longer required simply because it was traditionally collected in the past, but rather focus on key demographic, social and socio-economic variables.It becomes necessary, therefore, in consultation with a broad range of users of census data, to review periodically the topics traditionally investigated and to re-evaluate the need for the series to which they contribute, particularly in the light of new data needs and alternative data sources that may have become available for investigating topics formerly covered in the population census. It was against this background that Statistics South Africa conducted user consultations in 2008 after the release of some of the Community Survey products. However, some groundwork in relation to core questions recommended by all countries in Africa has been done. In line with users' meetings, the crucial demands of the Millennium Development Goals (MDGs) should also be met. It is also imperative that Stats SA meet the demands of the users that require small area data.

Accuracy of data depends on a well-designed questionnaire that is short and to the point. The interview to complete the questionnaire should not take longer than 18 minutes per household. Accuracy also depends on the diligence of the enumerator and honesty of the respondent.On the other hand, disadvantaged populations, owing to their small numbers, are best covered in the census and not in household sample surveys.Variables such as employment/unemployment, religion, income, and language are more accurately covered in household surveys than in censuses.Users'/stakeholders' input in terms of providing information in the planning phase of the census is crucial in making it a success. However, the information provided should be within the scope of the census.

2. Household identification particulars

3. Individual particulars Section A: Demographics Section B: Migration Section C: General Health and Functioning Section D: Parental Survival and Income Section E: Education Section F: Employment Section G: Fertility (Women 12-50 Years Listed) Section H: Housing, Household Goods and Services and Agricultural Activities Section I: Mortality in the Last 12 Months The Household Questionnaire is available in Afrikaans; English; isiZulu; IsiNdebele; Sepedi; SeSotho; SiSwati;Tshivenda;Xitsonga

Cleaning operations

Data editing and validation system The execution of each phase of Census operations introduces some form of errors in Census data. Despite quality assurance methodologies embedded in all the phases; data collection, data capturing (both manual and automated), coding, and editing, a number of errors creep in and distort the collected information. To promote consistency and improve on data quality, editing is a paramount phase in identifying and minimising errors such as invalid values, inconsistent entries or unknown/missing values. The editing process for Census 2011 was based on defined rules (specifications).

The editing of Census 2011 data involved a number of sequential processes: selection of members of the editing team, review of Census 2001 and 2007 Community Survey editing specifications, development of editing specifications for the Census 2011 pre-tests (2009 pilot and 2010 Dress Rehearsal), development of firewall editing specifications and finalisation of specifications for the main Census.

Editing team The Census 2011 editing team was drawn from various divisions of the organisation based on skills and experience in data editing. The team thus composed of subject matter specialists (demographers and programmers), managers as well as data processors. Census 2011 editing team was drawn from various divisions of the organization based on skills and experience in data editing. The team thus composed of subject matter specialists (demographers and programmers), managers as well as data processors.

The Census 2011 questionnaire was very complex, characterised by many sections, interlinked questions and skipping instructions. Editing of such complex, interlinked data items required application of a combination of editing techniques. Errors relating to structure were resolved using structural query language (SQL) in Oracle dataset. CSPro software was used to resolve content related errors. The strategy used for Census 2011 data editing was implementation of automated error detection and correction with minimal changes. Combinations of logical and dynamic imputation/editing were used. Logical imputations were preferred, and in many cases substantial effort was undertaken to deduce a consistent value based on the rest of the household’s information. To profile the extent of changes in the dataset and assess the effects of imputation, a set of imputation flags are included in the edited dataset. Imputation flags values include the following: 0 no imputation was performed; raw data were preserved 1 Logical editing was performed, raw data were blank 2 logical editing was performed, raw data were not blank 3 hot-deck imputation was performed, raw data were blank 4 hot-deck imputation was performed, raw data were not blank

Abstract

The 2011 Trinidad and Tobago Population and Housing Census was conducted by the Central Statistical Office of Trinidad and Tobago (CSOTT) during the period 9th January -31st May 2011. Trinidad and Tobago has maintained an unbroken tradition of conducting decennial Censuses dating back to 1851. The census was originally scheduled for 16th May - 30th June 2010, but was postponed when Parliament was prorogued before the Census Order – the legal authority for the conduct of the Census – was passed.

The 2011 Population and Housing Census was conducted as part of the CARICOM Secretariat’s regionally co-ordinated approach to census taking for the 2010 Round of Population and Housing Censuses. The Central Statistical Office of Trinidad and Tobago has actively participated as a member of the Regional Census Co-ordinating Committee (RCCC) of CARICOM, in the formulation of the regional strategy to promote the use of uniform concepts and definitions and a common core of questions for the purpose of producing comparable, high-quality data, which can be useful for monitoring social and demographic developments across the region.

This time around, the CSO employed Scanning Technology using Cardiff Teleform Application Software, instead of the method of direct data entry, which was used in the 2000 Census. The CSO acquired expertise in the use of scanning technology through its collaboration with the FAO for the 2004 Agriculture Census. The Data processing of the 450 000 questionnaires collected was undertaken by a Data Processing team consisting of an Information Technology Specialist, Database Administrator, Network Specialist, Network Technician, Scanning Supervisors, Verifier Supervisors, Scanning Operators Data Verifiers and Data-entry Staff.

Sampling procedure

The sampling frame for the PES was the complete list of Census 2011 EAs, amounting to 103 576 EAs. The primary sampling units (PSUs) were the Census EAs. The principle for selecting the PES sample is that the EA boundaries for sampled EAs should have well defined boundaries, and these boundaries should correspond with those of Census EAs to allow for item-by-item comparison between the Census and PES records. The stratification and sampling process followed will allow for the provision of estimates at national, provincial, urban (geography type = urban) and non-urban (geography type = farm and traditional) levels, but estimates will only be reliable at national and provincial levels. The sample of 600 EAs was selected and allocated to the provinces based on expected standard errors which were based on those obtained in PES 2001. Populations in institutions (other than Workers' Hostels), floating and homeless individuals were excluded from the PES sample.

The data files in the dataset include Household, Person, and Mortality files. The 10% sample for the Mortality data file was sampled separately and is not the same as the 10% sample for Household file and Person file.

Three sets of questionnaires were developed for Census 2011: 1. Questionnaire A - the household questionnaire - administed to the population in a household set-up including those households that were found within an institution, such as staff residences 2. Questionnaire B - the population in transit (departing) and those on holiday on reference night (9/10 October 2011). The homeless were also enumerated using this set of questions 3. Questionnaire C - the institutions questionnaire administered to the population in collective living quarters (people who spent census night 9/10 October 2011 at the institution)

A Post-Enumeration Survey was carried out after the census, which used a PES questionnaire.

In 2011 Statistics Canada replaced the "long form" census with a voluntary National Household Survey. The result of the survey will not be directly comparable with previous census data. In 2006 there were changes made to the definition of households. A number of Single Room Occupancy and Seniors facilities were considered to be dwellings in 2001, and collective dwellings in 2006. The City believes a similar change occurred on some properties between 2006 and 2011. This would explain why the numbers of "Apartments under 5 stories" has fallen in some locations.Note that for the first time in 2011, three language questions (knowledge of official languages, home language and mother tongue) were included on the census questionnaire that was administered to 100% of the population.Language data and analysis published for all censuses since 1996 have been based almost exclusively on responses from the long-form census questionnaire administered to 20% of the population. However, Statistics Canada has observed changes in patterns of response to both the mother tongue and home language questions that appear to have arisen from changes in the placement and context of the language questions on the 2011 Census questionnaire relative to previous censuses. As a result, Canadians appear to have been less inclined than in previous censuses to report languages other than English or French as their only mother tongue, and also more inclined to report multiple languages as their mother tongue and as the language used most often at home. Data currencyThe data for Census 2011 was collected in May 2011. Data accuracyStatistics Canada is committed to protect the privacy of all Canadians and the confidentiality of the data they provide to us. As part of this commitment, some population counts of geographic areas are adjusted in order to ensure confidentiality. Counts of the total population are rounded to a base of 5 for any dissemination block having a population of less than 15. Population counts for all standard geographic areas above the dissemination block level are derived by summing the adjusted dissemination block counts. The adjustment of dissemination block counts is controlled to ensure that the population counts for dissemination areas will always be within 5 of the actual values. The adjustment has no impact on the population counts of census divisions and large census subdivisions.

Abstract

The Census is the official count of population, dwellings and households in Tonga and it provides a ‘snapshot’ of the country at one specific point in time: 30th of November 2011. A Tonga census has been taken once in every ten years since 1956. However the population census of 2011 is the first population census by 5 year interval from the previous census in 2006 due to the Electoral Boundary Commission (EBC)'s request according to its Act 2010.

The census provides a unique source of detailed demographic, social and economic data relating the entire population and its most precious resource of its people. This information is used for policy making and planning, monitoring and evaluation, research and other decision-making.

The census is often the primary source of information such as used for allocation of public funding, especially in areas such as health, education and social policy. The main users of this information are the government, local authorities, education facilities (such as schools and tertiary organizations), businesses, community organizations and the public in general.

Research instrument

The questionnaires for the 2011 Tonga Census of Population and Housing were structured based on the one from 2006 Tonga Census of Population and Housing with some modifications and additions. There were mainly two questionnaires, one is the household questionnaire and the other is the personal questionnaire.

The household questionnaire was designed for each household to collect various information of the dwelling's characteristics, housing utilities and durable goods, household waste disposal, information technology, income, remittances and the mortality.

The personal questionnaire includes personal characteristics, migration, disability, smoking habit, education, labour and employment, voting eligibility, and fertility. Some questions has age restrictions like the education and qualification, literacy, smoking habits questions were ask to 5 years and older only. Labour, employment and fertility questions were for 15 years and older only. And the electoral vote questions were eligible only for 22 years and older e.g. for those that turned 21 in November 2010. This questionnaire is split into 3 categories and form 3 questionnaires: 1) Personal Questionnaire: for individual in a household 2) Questionnaire For Institution Tongan Residents: for resident in an institution 3) Personal Questionnaire For Institution Resident (Visitors/Foreigners): for visitor/ foreigner in an institution

Census of population and housing refers to the entire process of collecting, compiling, evaluating, analyzing, and publishing data about the population and the living quarters in a country. It entails the listing and recording of the characteristics of each individual person and each living quarter as of a specified time and within a specified territory. It is the source of information on the size and distribution of the population as well as its demographic, social, economic, and cultural characteristics. These information are vital for making rational plans and programs for national and local development.

In April 2011, a national census of population and housing was conducted in the Republic of the Marshall Islands (RMI). It is the 11th census of population to be undertaken in this century since the first census was undertaken in 1920.

The 2011 Census of Population and Housing is designed to take an inventory of the total population and housing units in the RMI and to collect information about their characteristics. The census of population is the source of information on the size and distribution of the population as well as information about the demographic, social, economic and cultural characteristics. The census of housing, on the other hand, provides information on the supply of housing units, their structural characteristics and facilities which have bearing on the maintenance of privacy, health and the development of normal family living conditions. These information are vital for making rational plans and programs for social and economic development.

Abstract

National population and housing census 2011 (NPHC2011), marks a hundred years of census taking in Nepal. Nepal has been conducting population censuses almost decennially and the census 2011 is the eleventh. The first population census was conducted in 1911 A.D. (1968 B.S.). However, the census conducted in 1952/54 is considered to be the first modern census of Nepal introducing internationally comparable concepts, definitions and classifications. Computer processing was introduced for the first time in 1971 census using IBM 1401. NPHC 2011 carries special features of having scientific questionnaires, detailed EA maps for urban and Village Development Committees (VDC) maps for rural areas, ever most inclusive field staff, extensive publicity, independent observance by civil society, most economic operation based on domestic resources and most reliable data processing.

Census questionnaires (Listing form, Individual form-1, Individual form-2), enumeration and other manuals, EA maps were major tools used to conduct field enumeration. Complete list of households was prepared during May and June 2011, a month before the main census. Listing schedule contains questions on number of house, households, household members by sex, agricultural land operated and livestock owned by households and operation of small scale nonagricultural activities. Individual Form-1 contains questions on types of house, household facilities/assets, ownership of the house or land of female members of the household, mortality and its causes and details of absent members of households. Also, included in the form-1 are name, surname, relationship to head, sex, age, caste/ethnicity, marital status and age at first marriage, religion, mother tongue and second language, citizenship, type of disability, literacy and level of education. However, questions on migration, fertility, labour force, occupation, industry, employment status and living arrangement of children (under the age 16) were asked under form-2 to every eighth household selected systematically.

Cleaning operations

Keeping in mind the quality of the data processing operation and the capacity of CBS to undertake, it has been decided to source out the operation as it was done in 2001 census. Nevertheless, processing site and the computers were provided to the contractor so that both quality and confidentiality lie strictly under the control of CBS. Manuals of coding, editing and key entry operation were prepared, training and key entry operation were monitored and supervised by the core team of the CBS. Despite delay in awarding the contract, the whole operation was completed in six months from the date the contract was signed. Approximately, six hundred processing staff plus experts were engaged in coding, editing, key entry operation and verification.

CSPro, an integrated software developed for data entry, editing, verification and tabulation by US Bureau of Census was used for data processing (Key entry, editing and verification). However, CSPro, SPSS and STATA are used for tabulations. Range and consistency checks were done thoroughly during the processing operation. The captured data were further cleaned with the assistance of international experts. New classifications of occupation and industry were prepared based on ISOC and ISIC (Rev. 4). Similarly, classifications of caste/ethnicity, religion and language were prepared based on the recommendations of the academicians and subject matter specialists.

Data editing for the 2011 RMI Census used four phases of editing. The first phase of the data editing was the control phase which control clerks checked for completeness of the questionnaire. During this phase, items were verified by contacting the respondents either by phone or by home visit. The countries took advantage of enumerators still on the field to complete any missing information especially those pertaining to the head of the household, education and fertility questions. The second phase of data editing was completed during data entry on items that had responses in places where no responses was expected and vice versa. Any information that was missing or incomplete in the questionnaire was substituted with a special code and keyed into the computer. Other than corrections to age, sex to name association and skip patterns no other information was edited during this phase. The third phase utilized a standardized editing method called dynamic imputation. The method imputes missing or invalid items in the questionnaire with a person in the same geographical region that displays similar characteristics. The method used an approach called top-down to prevent circular and over editing of data. The forth phase was more of a quality control issue and refinements to the data edits. This was normally done with the production of tables and the interaction of subject matter specialist.

The Australian Census Longitudinal Dataset (ACLD) brings together a 5% sample from the 2006 Census with records from the 2011 Census to create a research tool for exploring how Australian society is changing over time. In taking a longitudinal view of Australians, the ACLD may uncover new insights into the dynamics and transitions that drive social and economic change over time, conveying how these vary for diverse population groups and geographies. It is envisaged that the 2016 and successive Censuses will be added in the future, as well as administrative data sets. The ACLD is released in ABS TableBuilder and as a microdata product in the ABS Data Laboratory. \r \r The Census of Population and Housing is conducted every five years and aims to measure accurately the number of people and dwellings in Australia on Census Night. \r \r Microdata products are the most detailed information available from a Census or survey and are generally the responses to individual questions on the questionnaire. They also include derived data from answers to two or more questions and are released with the approval of the Australian Statistician.\r The following microdata products are available for this longitudinal dataset: \r •ACLD in TableBuilder - an online tool for creating tables and graphs. \r •ACLD in ABS Data Laboratory (ABSDL) - for in-depth analysis using a range of statistical software packages.\r \r

Abstract

The 2011 Mauritius Housing & Population Census will be carried out by the Central Statistics Office in two distinct rounds: the Housing Census from 31 January 2011 to June 2011 followed by the Population Census from 20 June to 31 July 2011 in respect of all persons alive on the night of 3 - 4 July 2011. The main objective of the Housing and Population census is to provide up-to-date and disaggregated data on the housing conditions, the spatial distribution, and the demographic and socio-economic characteristics of the Mauritian population.

Census/enumeration data [cen]

Sampling procedure

Census 2011, like the four previous ones, was taken in two distinct rounds: the Housing Census followed by the Population Census four months later. This enumeration procedure was adopted in order to obtain at the Housing Census a list of names and addresses of heads of households which served as frame for the Population Census.

Mode of data collection

Face-to-face [f2f]

Research instrument

4.1 Questionnaire design The questionnaire type, format and contents were determined on the basis of the following factors:

Data to be collected Data collected were in line with UN recommendations and, in addition, catered for local data needs.

Method of enumeration For Census 2011, the questionnaires were completed by enumerators who carried out field interviews.

Data capture and processing techniques The office used scanning and recognition technology for census data capture directly from the questionnaires.

4.2 Contents of questionnaire The questionnaire contents were determined as follows: (i) The data needs of main stakeholders from Government Ministries and Departments were considered. As from 2008, heads of Government Ministries and Departments were invited via a circular letter to submit their requirements for demographic, social and economic data considered essential for administration, planning and policy-making and which could be collected at the census. Topics were retained after considering: - their usefulness to the country; - the cost for data collection and processing - where it is possible by other means to obtain satisfactory information more cheaply, the topic was not selected; and - their suitability for data collection at a Census - sensitive and controversial issues as well as questions that are too complicated or difficult for the average respondent to answer were avoided. (ii) The concepts and questions used for the previous census were examined for relevance and only those found relevant were kept. (iii) The latest “Principles and Recommendations for Population and Housing Censuses” were reviewed to determine whether to add questions or to modify existing questions. (iv) The questions thus arrived at were tested during a pilot census conducted in September 2010. In the light of observations made on the field, some changes were made to the wording and sequence of the questions and a final set of questions adopted. 4.2.1 The Housing Census questionnaire The Housing Census questionnaire covered all topics and items covered at Census 2000; some new items were added for the reasons given in the column “Remarks”.

The questionnaire was designed to cover 1 housing unit, up to two households, up to three planters and 1 commercial/industrial establishment, guest house or tourist residence. More than one questionnaire was used in other cases.

4.2.2 The Population Census questionnaire The 2011 Population Census questionnaire included the topics covered at the 2000 Population Census except that on income. Questions were added on National Identity number of each person as well as on residence for the reasons mentioned in the column “Remarks”.

4.3 Questionnaire layout and size The layout and design of response areas was done to ensure optimum conditions for data capture through scanning and recognition technology. The layout was also influenced by the cost (the number of pages had to be kept to a minimum to cut down on paper, printing and scanning costs) while at the same time ensuring ease of recording the answers on the field.

The quality of information collected depends not only on the training of field workers, but also on the day-to-day control and supervision of the fieldwork. Supervisors had to accompany each of their Enumerators in the first visits to ensure that interviews were done according to instructions given and that all concepts were clearly understood. Surprise and pre-arranged field checks as well as re-interviews also helped to increase the reliability of the information collected. Furthermore, Supervisors had to check all completed questionnaires at the early stage of enumeration and later a sample of the completed questionnaires to ensure that the quality of work was satisfactory. Meetings were held regularly to take stock of the field situation and to solve problems met on the field.

All supervisory staff had to record their field activities in provided diaries. The day-today record outlined the activities carried out, the dates and the places at which the activities were carried out, problems encountered and remedial actions taken. The day-to-day recording of activities allowed supervisory staff to follow the progress of work and to assess the performance of each and every staff working under their supervision. Furthermore, it ensured that supervisory control prevailed all along the fieldwork.

The dataset shows sex by single year of age for each of the 21 multi-member wards in Glasgow based on the 2011 Census outcomes. Age is dreived from the date of birth question and it is the person's age as at when the cenus was conducted on the 27th of March 2011.

The UK censuses took place on 27 March 2011. They were run by the Northern Ireland Statistics & Research Agency (NISRA), National Records of Scotland (NRS), and the Office for National Statistics (ONS) for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.

Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics and underpin funding allocation to provide public services. This is the home for all UK census data.

Census flow data involve flows of individuals in the UK between origins and destinations. These flows are either the residential migrations of individuals from one place of usual residence to another, or of commuters making journeys from home to workplace or place of study.

These data are derived from the questions on the census form relating to usual place of residence one year ago, and the place of work for the respondent's main job. Flow data are currently available at a range of different spatial scales ranging from Output Areas to Local Authority Districts.


Main Topics:


The Census Support: Flow Data website facilitates access to the interaction data for members of UK higher and further education institutions. Access is provided through the Web-based Interface to Census Interaction Data (WICID).

The 2011 sets currently held include:

• Census migration datasets: Special Migration Statistics. Migration data at Local Authority District, Ward, and Output Area level.
• Special Student Statistics: Migration data at Local Authority District, Ward, and Output Area level.
• Census commuting datasets: Special Workplace Statistics: Commuting data at Local Authority District, Middle-layer Super Output Area, Intermediate Zone (for Scotland), Workplace Zone (for England and Wales), and Output Area level.
• Census second residence datasets: Special Residence Statistics. Commuting data at Local Authority District, Ward, and Output Area level.

Explicit registration is not required for the 2011 Census products that have been released under the Open Government Licence. However, outputs from the 2011 Census classified as 'safeguarded' require users to agree on additional terms and conditions. Access to these datasets is only permitted via Federated Access.

The Flow Data website provides two basic routes to the data.

• WICID is the main route to the flow data. It provides a flexible service to download extracts of data in a variety of forms;
• the Downloads page allows users to download the original tables as released by ONS.

The National Household Survey (NHS) was conceived to replace the mandatory long-form census questionnaire. The content of the NHS 2011 is similar to the past long-form questionnaire, although some questions and sections have changed. This profile presents information from the 2011 National Household Survey (NHS) for various levels of geography, including provinces and territories, census metropolitan areas/census agglomerations, census divisions, census subdivisions, dissemination areas, federal electoral districts, and forward sortation areas. The forward sortation areas profile was created as a custom tabulation by the University of Toronto, and subsequently shared with ODESI and the DLI. NHS data topics include: Immigration and Ethnocultural Diversity; Aboriginal Peoples; Education and Labour; Mobility and Migration; Language of work; Income and Housing. 2011 Census data topics include: Population and dwelling counts; Age and sex; Families, households and marital status; Structural type of dwelling and collectives; and Language. The Aboriginal Population Profile presents information on the Aboriginal identity population from the 2011 National Household Survey (NHS). The profile for the NHS Special Collection for 13 Indian reserves and Indian settlements in Northern Ontario provides information from a special data collection following the 2011 National Household Survey (NHS).
