These data are from the 20-, 15-, and 5-percent samples of the 1970 United States Census of Population and Housing, and contain population characteristics such as education, occupation, income, citizenship, and vocational training. Separate tallies are shown for whites, Blacks, Hispanic Americans (referred to as Spanish Americans in the 1970 Census), and the total population. The unit of observation for these data files is the census tract. There is one file for each of 48 states and the District of Columbia. The Census Bureau did not issue data for Vermont and Wyoming because these two states were untracted in 1970.

This data collection contains 132 Public Use Microdata Samples (PUMS) files from the 1970 Census of Population and Housing. Information is provided in these files on the housing unit, such as occupancy and vacancy status of house, tenure, value of property, commercial use, year structure was built, number of rooms, availability of plumbing facilities, sewage disposal, bathtub or shower, complete kitchen facilities, flush toilet, water, telephone, and air conditioning. Data are also provided on household characteristics such as the number of persons aged 18 years and younger in the household, the presence of roomers, boarders, or lodgers, the presence of other nonrelative and of relative other than wife or child of head of household, the number of persons per room, the rent paid for unit, and the number of persons with Spanish surnames. Other demographic variables provide information on age, race, marital status, place of birth, state of birth, Puerto Rican heritage, citizenship, education, occupation, employment status, size of family, farm earnings, and family income. This hierarchical data collection contains approximately 214 variables for the 15-percent sample, 227 variables for the 5-percent sample, and 117 variables for the neighborhood characteristics sample. (Source: downloaded from ICPSR 6/9/2011). In addition to the housing unit and person characteristics which appear in each public use sample, these filed contain census characteristics of the area in which the person lives. The specific neighborhoods are not identified by name but represent the size of census tracts, which contain around 4,000 people.

Analysis unit

Persons, households, and dwellings Excludes 2 states: Sabah and Sarawak

UNITS IDENTIFIED: - Dwellings: yes - Vacant Units: no - Households: yes - Individuals: yes - Group quarters: yes

UNIT DESCRIPTIONS: - Dwellings: Living quarters have been defined for census purposes as places of abode, which are structurally separate and independent. The terms separate and independent mean the following: Separate: A structure is considered separate if it is surrounded by walls, fence, etc., and is covered by roof. Independent: A structure is said to be independent if it has direct access via a public staircase, communal passageway or landing (that is, occupants can come in or go out of their living quarters without passing through someone else’s premises). In general, living quarters can be classified into two categories, that is: (i) Built or converted for living (e.g. house, flat, apartment, shophouse, makeshift hut, hotel, hostels, etc.) (ii) Not meant for living but used for this purpose on Census Day (e.g. in a building such as office, shop, barn, community hall, etc.) Living quarters built or converted for living can be further classified into housing units and collective living quarters. Housing units are classified into six main types, namely: House; Flat/apartment/condominium; Shop house, office; Room (with direct access to the outside); improvised/temporary hut; and others. House can be further classified into Detached house; and Semi-detached house. - Households: A household consists of a group of persons who live together and make common provision for food and other essentials of living. The group pay for main meals out of a commond budget and have common arrangements for basic needs. A household may either be a one person household or a multi-person household. The persons may be related by blood or marriage, or unrelated, or a combination of both. - Group quarters: Living quarters which is built or converted for living (e.g. house, flat, apartment, shophouse, makeshift hut, hotel, hostels, etc.).

The 1970 Population Census was de facto count of all persons in the country on the midnight of August 24/25, 1970. However, the manner in which certain categories of persons were enumerated varied. Nomads - In Malaysia, nomads are to be found amongst the Orang Asli. (Aborigines). The Department of Orang Asli assisted in enumerating the Orang Asli. Persons living in remote areas – The problem of persons living in remote and inaccessible areas was a particular problem in Sabah and Sarawak. In these areas, the two-stage system of enumeration was not employed, and the count was undertaken as a single operation. Resident merchant, seamen and fishermen at sea on Census Night – In the Census these persons were designated as persons afloat. They were categorised into the following groups and with the exception of the last group (e), they were included in the Census Count: (a) Crew and passengers on coastal ships sailing in Malaysian waters or at Malaysian ports or sailing between two Malaysian ports, (b) Crew and passengers on vessels registered in Malaysia and engaged in regional trade, (c) Persons living on boats and vessels moored in harbours, rivers or creeks, (d) Fishermen at sea on Census Night, and (e) Crew and passengers on foreign registered ships in port or in Malaysian waters. Civilian residents who cross a frontier daily to work in another country – This category of persons was included in the Census in conformity with the principle of counting all persons present in the country on the night of August 24/25, 1970. Civilian aliens who were temporarily in the country as seasonal workers were included in the Census count. So were all other Civilian aliens, other than those already listed, working in the country. Also, civilian aliens, other than those already listed, temporarily in the country were included in the count. Foreign military, naval and diplomatic personnel and their families located in the country – All persons in this category were included in the Census count with the exception of persons claiming diplomatic immunity. Wayfarers, homeless people and persons in hotels were included in the Census count – Special arrangements were made with the police and railway authorities to enumerate these persons. Recourse was made to road blocks to count travellers. Military, naval and diplomatic personnel and their families located outside Malaysia were excluded from the Census count. Given the de facto approach, which requires only a count of persons present within Malaysia, these categories of persons were excluded from the count. Similarly, civilians who were temporarily away from the country on the night of the Census, were excluded. Civilian residents, other than those already listed, working in another country were also excluded from the count. So were civilian residents, other than those already listed, temporarily absent from the country. Civilian aliens who cross a frontier daily to work in Malaysia were omitted from the count.

One in five housing units in 1970 received a long form containing supplemental sample questions. There were two versions of the long form, with different inquiries on both housing and population items; 15 percent of households received one version, and 5 percent received the other. Six independent 1 percent public use samples were produced for 1970, three from the 15 percent questionnaire and three from the 5 percent questionnaire. IPUMS-International uses the "Form 2 Metro" sample.

The 1970 Census School District Data Tape (SDDT) User's Guide was designed to complement the 1970 Census User's Guide prepared by the United States Census Bureau. The School District Data Tape (SDDT) created by the National Center for Education Statistics is a recompilation of the 1970 Census Fourth Count Population data, providing data tables for each school district in the country with 300 or more students. The preparation of the School District Data Tape required three major steps: (1) overlaying school district boundaries on census maps, (2) creating a geo-reference tape indicating the percent of each census area falling within each school district, and (3) merging the geo-reference tape with the 1970 Census Fourth Count Population Files A (Traced Areas) and B (Minor Civil Divisions). Some of the major uses of the School District Data Tape include: allocation of federal funds, desegregation planning, bilingual and minority special education planning, preschool and child care planning, facility planning, redistricting, urban-suburban-rural analyses, mobility analysis, social and economic inequality among school districts, and school children profiles. In addition to these uses, most state education agencies will find data by school district of value in allocating federal and state aid to school districts and in the evaluation of the inequality of property taxes as a basis for financing elementary and secondary education. The School District Data Tape matches, as closely as possible, the format of the Fourth Count (Population) Summary tapes supplied by the Census Bureau.

Abstract

The 1970 South African Population Census was an enumeration of the population and housing in South Africa.The census collected data on dwellings and individuals' demographic, migration, family and employment details.

Geographic coverage

National coverage of the so-called white areas of South Africa, i.e. the areas in the former four provinces of the Cape, the Orange Free State, Transvaal, and Natal, and the so-called National States of Ciskei, KwaZulu, Gazankulu, Lebowa, Qwaqwa, Kangwane, Kwandebele, Transkei and Bophuthatswana.

Analysis unit

The units of analysis for the South African Census 1970 were households and individuals

Universe

The South African population census of 1970 covered all de jure household members (usual residents) of South Africa and the "national states".

The Census was enumerated on a de facto basis, that is, according to the place where persons were located during the census. All persons who were present on Republic of South African territory during census night were enumerated and included in the data. Visitors from abroad who were present in the RSA on holiday or business on the night of the census, as well as foreigners (and their families) who were studying or economically active, were not enumerated and included in the figures. Likewise, members of the Diplomatic and Consular Corps of foreign countries were not included. However, the South African personnel linked to the foreign missions including domestic workers were enumerated. Crews and passengers of ships were also not enumerated, unless they were normally resident in the Republic of South Africa. Residents of the RSA who were absent from the night were as far as possible enumerated on their return and included in the region where they normally resided. Personnel of the South African Government stationed abroad and their families were, however enumerated. Such persons were included in the Transvaal (Pretoria).

Kind of data

Census/enumeration data [cen]

Sampling procedure

The 1970 Census was a full count for Whites, Coloureds and Asians, and a 5% sample for Blacks (Africans)

Sampling deviation

The country was divided into 400 census districts for the 1970 Census. In most cases the boundaries of the census districts corresponded with those of the magisterial districts. However, in some cases the boundaries did not correspond, particularly in the areas in and around the "National States". This was to facilitate the administration of the census and to make it easier to exclude figures of the "National states" from provincial totals.

Mode of data collection

Research instrument

The 1970 Population Census of the Republic of South Africa questionnaires were: Form 01, to be completed by "Whites, Coloured and Asiatics" Form 02, to be completed by "Bantu" Form 03, for families, households and dwellings

Form 01 collected data on relationship to household head, population group, sex, age, marital status, place of birth, and citizenship, as well as usual place of residence, home language, religion, level of education and income. Employment data collected included occupation, employment status and industry type.

Form 02 collected data for African South Africans on relationship to household head, sex, age, marital status, fertility, place of birth, home language and literacy, religion and level of education. Employment data collected included occupation, employment status and industry type.

Form 03 collected household data, including data on dwelling type, building material of dwelling walls, number of rooms and age of the dwelling. Data on home ownership. Data was also collected on the number and sex of household members and their relationship to the household head. Data on household heads included their population group, age and marital status. Income data was also collected, for husbands and wives. Data on home ownership, household size and domestic workers was also collected, but for Urban households only.

This documentation has been created by ICPSR for the restricted version of Census 1970 distributed by the Bureau of the Census. The restricted data is based on questions from the long form questionnaire, and was collected from one in six households in the United States. Topics covered include income, ancestry, citizenship status, home values, commute time to work, occupation, education, veteran status, language ability, migration, place of birth, and many others. The documentation available here provides files summaries, variable information, and facilitates sorting of the data by race or by a wide variety of geographical units. ICPSR is not distributing the restricted data, only the documentation for it. Users who wish to access the restricted data can find more information at the Michigan Census Research Data Center Web site. Users should also note that the data for the public versions of Census 1970 are available from ICPSR.
