Abstract

The National Family Health Survey 2019-21 (NFHS-5), the fifth in the NFHS series, provides information on population, health, and nutrition for India, each state/union territory (UT), and for 707 districts.

The primary objective of the 2019-21 round of National Family Health Surveys is to provide essential data on health and family welfare, as well as data on emerging issues in these areas, such as levels of fertility, infant and child mortality, maternal and child health, and other health and family welfare indicators by background characteristics at the national and state levels. Similar to NFHS-4, NFHS-5 also provides information on several emerging issues including perinatal mortality, high-risk sexual behaviour, safe injections, tuberculosis, noncommunicable diseases, and the use of emergency contraception.

The information collected through NFHS-5 is intended to assist policymakers and programme managers in setting benchmarks and examining progress over time in India’s health sector. Besides providing evidence on the effectiveness of ongoing programmes, NFHS-5 data will help to identify the need for new programmes in specific health areas.

The clinical, anthropometric, and biochemical (CAB) component of NFHS-5 is designed to provide vital estimates of the prevalence of malnutrition, anaemia, hypertension, high blood glucose levels, and waist and hip circumference, Vitamin D3, HbA1c, and malaria parasites through a series of biomarker tests and measurements.

Sample survey data [ssd]

Sampling procedure

A uniform sample design, which is representative at the national, state/union territory, and district level, was adopted in each round of the survey. Each district is stratified into urban and rural areas. Each rural stratum is sub-stratified into smaller substrata which are created considering the village population and the percentage of the population belonging to scheduled castes and scheduled tribes (SC/ST). Within each explicit rural sampling stratum, a sample of villages was selected as Primary Sampling Units (PSUs); before the PSU selection, PSUs were sorted according to the literacy rate of women age 6+ years. Within each urban sampling stratum, a sample of Census Enumeration Blocks (CEBs) was selected as PSUs. Before the PSU selection, PSUs were sorted according to the percentage of SC/ST population. In the second stage of selection, a fixed number of 22 households per cluster was selected with an equal probability systematic selection from a newly created list of households in the selected PSUs. The list of households was created as a result of the mapping and household listing operation conducted in each selected PSU before the household selection in the second stage. In all, 30,456 Primary Sampling Units (PSUs) were selected across the country in NFHS-5 drawn from 707 districts as on March 31st 2017, of which fieldwork was completed in 30,198 PSUs.

For further details on sample design, see Section 1.2 of the final report.

Mode of data collection

Computer Assisted Personal Interview [capi]

Research instrument

Four survey schedules/questionnaires: Household, Woman, Man, and Biomarker were canvassed in 18 local languages using Computer Assisted Personal Interviewing (CAPI).

Cleaning operations

Electronic data collected in the 2019-21 National Family Health Survey were received on a daily basis via the SyncCloud system at the International Institute for Population Sciences, where the data were stored on a password-protected computer. Secondary editing of the data, which required resolution of computer-identified inconsistencies and coding of open-ended questions, was conducted in the field by the Field Agencies and at the Field Agencies central office, and IIPS checked the secondary edits before the dataset was finalized.

Field-check tables were produced by IIPS and the Field Agencies on a regular basis to identify certain types of errors that might have occurred in eliciting information and recording question responses. Information from the field-check tables on the performance of each fieldwork team and individual investigator was promptly shared with the Field Agencies during the fieldwork so that the performance of the teams could be improved, if required.

Response rate

A total of 664,972 households were selected for the sample, of which 653,144 were occupied. Among the occupied households, 636,699 were successfully interviewed, for a response rate of 98 percent.

In the interviewed households, 747,176 eligible women age 15-49 were identified for individual women’s interviews. Interviews were completed with 724,115 women, for a response rate of 97 percent. In all, there were 111,179 eligible men age 15-54 in households selected for the state module. Interviews were completed with 101,839 men, for a response rate of 92 percent.

Tribal or indigenous communities have unique health behaviors, challenges, and inequities that nationally representative surveys cannot document. Odisha has one of India’s largest and most diverse tribal populations, constituting more than a fifth of the state. State and tribe-specific health data generation is recommended in India’s national roadmap of tribal health. The Odisha tribal family health survey (OTFHS) aims to describe and compare the health status of tribal communities in the state of Odisha and to estimate the prevalence of key maternal-child health indicators and chronic diseases. This paper summarizes the methodology, protocols, and tools used in this survey. This is a population-based cross-sectional survey with a multistage random sampling design in 13 (tribal sub-plan areas) districts of Odisha, India. We will include participants of all age groups and gender who belong to tribal communities. The sample size was calculated for each tribe and aggregated to 40,921, which will be collected from 10,230 households spread over 341 clusters. The survey data will be collected electronically in modules consisting of Village, Household, and Individual level questionnaires. The age-group-specific questionnaires were adapted from other national family health surveys with added constructs related to specific health issues of tribal communities, including-critical indicators related to infectious and non-communicable diseases, multimorbidity, nutrition, healthcare-seeking behavior, self-rated health, psycho-social status, maternal and child health and geriatric health. A battery of laboratory investigations will be conducted at the household level and the central laboratory. The tests include liver function tests, kidney function tests, lipid profile, iron profile, and seroprevalence of scrub typhus and hepatitis infections. The datasets from household questionnaires, field measurements and tests and laboratory reports will be connected using a common unique ID in the database management system (DBMS) built for this survey. Robust quality control measures have been built into each step of the survey. The study examines the data focused on different aspects of family health, including reproductive health, adolescent and child health, gender issues in the family, ageing, mental health, and other social problems in a family. Multistage random sampling has been used in the study to enable comparison between tribes. The anthropometric measurements and biochemical tests would help to identify the indicators of chronic diseases among various age groups of the population.

The purpose of the Survey of Jails in Indian Country is an enumeration of all known adult and juvenile facilities -- jails, confinement facilities, detention centers, and other correctional facilities operated by tribal authorities or the Bureau of Indian Affairs (BIA), U.S. Department of the Interior. For the purpose of this collection, Indian country includes reservations, pueblos, rancherias, and other Native American and Alaska Native communities throughout the United States. The survey collects data on the number of adults and juveniles held on the last weekday in June 2023, type of offense, average daily population in June, most crowded day in June, admissions and releases in June, number of inmate deaths and suicide attempts from July 1, 2022 through June 30, 2023, rated capacity on June 30, and jail staffing on June 30, 2023.

Abstract

ABSTRACT OF ECONOMIC CENSUS IN INDIA

1. GENESIS

A reliable and robust database is the foundation of organized and proper planning. TheCentral Statistics Office (CSO), since its inception, has been instrumental in creation of database forvarious sectors of the economy and its periodic updation so as to meet the requirements of the plannersfor sound and systematic planning both at the macro as well as micro levels. While data requirementsmay be enormous in various sectors, the judicious collection and maintenance of data for varioussectors within the available resource is a challenge. Our economy can broadly be classified into twosectors, namely, Agricultural and Non-Agricultural sectors. Fairly reasonable database exists forAgricultural Sector whereas such data base for Non-Agricultural sector is much desired. Keeping inview the importance of the non-agricultural sector in the economy and non-availability of basic framefor adoption in various sampling techniques for collection of data and estimation of various parameters,conducting Economic Census was felt necessary. With this background, the CSO started EconomicCensus for preparing frame of establishments, particularly the ‘area frame’ which could be used forvarious surveys for collection of detailed data, mainly on non-agricultural sector of the economy.

1. EARLIER ATTEMPTS

Broadly the entire planning period may be divided into two: prior to conduct of the FirstEconomic Census i.e. prior to 1977 and thereafter i.e. after the economic census was carried outperiodically. Efforts to fill up the data gaps for the non-agricultural sector were made right from thebeginning of the First Five Year Plan. The first National Sample Survey (NSS) round (1950-51)covered non-agricultural household establishments as one of its subject themes. Such establishmentswere covered regularly up to the tenth NSS round (1955-56). Subsequently, selected activities weretaken up for survey intermittently in different rounds (14th, 23 rd & 29th rounds). Establishmentschedules were canvassed in 1971 population census. The census of unorganized industrial units wascarried out during 1971 -73. Census of the units falling within the purview of Development Commissioner, Small Scale Industries, was carried out during 1973-74 and a survey on distributivetrade was conducted by some of the States during the Fourth Five-Year Plan period (1969-74). Allsuch efforts made prior to 1977 to collect data on non-agricultural establishments have been partial andsporadic. Area sampling with probability proportional to population were mostly used even to captureestablishments. For a survey of establishments such sample design is not only inefficient but alsoresults in under coverage of desired number of establishments and low reliability of the estimatesderived. The prolonged efforts of statisticians and planners in finding a way out for collection ofinformation on amorphous areas of activity resulted in a decisive breakthrough with the advent ofconduct of Economic Census.

1. ECONOMIC CENSUSES CONDUCTED IN THE PAST

The Economic Enquiry Committee set up in 1925 under the Chairmanship of Dr.Visweswarayya and more importantly the Bowley-Robertson Committee set up later in 1934, were mainly responsible for the government’s decision to set up an Inter-Departmental Committee with theEconomic Adviser to the Government of India as the chairman. The Inter-Departmental Committeerecommended the formation of a Central Statistical Office for coordination, institution of a statisticalcadre, establishment of State Bureaus at State Head Quarters and maintenance of important statisticsfor the entire country. Bowley and Robertson Committee also commissioned a study to explore thepossibility of conducting economic censuses in India. The first coordinated approach was made by theerstwhile Central Statistical Organisation (CSO), Government of India, by launching a plan scheme'Economic Census and Surveys' in 1976. The scheme envisaged organising countrywide census of alleconomic activities (excluding those engaged in crop production and plantation) followed by detailedsample surveys of unorganised segments of different sectors of non-agricultural economy in a phasedmanner during the intervening period of two successive economic censuses.The basic purpose of conducting the economic census (EC) was to prepare a frame for followup surveys intended to collect more detailed sector specific information between two economiccensuses. In view of the rapid changes that occur in the unorganised sectors of non-agriculturaleconomy due to high mobility or morbidity of smaller units and also on account of births of new units,the scheme envisaged conducting the economic census periodically in order to update the frame fromtime to time.

1. First Economic Census (EC -1977) and Follow Up Surveys

The First Economic Census was conducted throughout the country, except Lakshadweep,during 1977 in collaboration with the Directorate of Economics & Statistics (DES) in the States/UnionTerritories (UT). The coverage was restricted to only non-agricultural establishments employing atleast one hired worker on a fairly regular basis. Data on items such as description of activity, number ofpersons usually working, type of ownership, etc. were collected.Reports based on the data of EC-1977 at State/UT level and at all India level were published.Tables giving the activity group-wise distribution of establishments with selected characteristics andwith rural and urban break up were generated. State-wise details for major activities and size-class ofemployment in different establishments, inter-alia, were also presented in tables.Based on the frame provided by the First Economic Census, detailed sample surveys werecarried out during 1978-79 and 1979-80 covering the establishments engaged in manufacturing, trade,hotels & restaurants, transport, storage & warehousing and services. While the smaller establishments(employing less than six workers) and own account establishments were covered by National SampleSurvey Organisation (NSSO) as a part of its 33rd and 34th rounds, the larger establishments were covered through separate surveys by the CSO. Detailed information on employment, emoluments,capital structure, quantity & value of input, output, etc. were collected and reports giving all importantcharacteristics on each of the concerned subjects were published.

1. Second Economic Census (EC-1980) and Follow Up Surveys

The Second Economic Census was conducted in 1980 along with the house-listing operations ofPopulation Census 1981. This was done with a view to economizing resources, manpower, time andmoney. The scope and coverage were enlarged. This time all establishments engaged in economicactivities - both agricultural and non-agricultural whether employing any hired worker or not werecovered, except those engaged in crop production and plantation. All States/UTs were covered withthe sole exception of Assam, where Population Census 1981 was not conducted.The information on location of establishment, description of economic activity carried out,nature of operation, type of ownership, social group of owner, use of power/fuel, total number ofworkers usually engaged with its hired component and break-up of male and female workers werecollected. The items on which information were collected in Second Economic Census were more orless the same as those collected in the First Economic Census. However, based on experience gained inthe First Economic Census certain items viz. years of operation, value of annualoutput/turnover/receipt, mixed activity or not, registered/ licensed/recognised and act or authority, ifregistered were dropped.The field work was done by the field staff consisting of enumerators and supervisors employedin the Directorate of Census Operations of each State/UT. The State Directorates of Economics &Statistics (DES) were also associated in the supervision of fieldwork. Data processing and preparationof State level reports of economic census and their publication were carried out by the DES.Based on the frame thrown up by EC-1980, three follow-up surveys were carried out, one in1983-84 on hotels & restaurants, transport, storage & warehousing and services, second in 1984-85 onunorganised manufacturing and third in 1985- 86 on wholesale and retail trade.The economic census scheduled for 1986 could not be carried out due to resource constraints.However, the EC- 1980 frame was updated during 1987-88 in 64 cities (12 cities having more than 10lakh population and 52 other class-I cities) which had problems of identification of enumerationblocks and changes due to rapid urbanization. On the basis of the updated frame, four follow-upsurveys were conducted during 1988-89, 1989-90, 1990-91 and 1991-92 covering the subjects ofhotels & restaurants and transport, unorganized manufacturing, wholesale & retail trade and medical,educational, cultural & other services respectively.

1. Third Economic Census (EC-1990) and Follow Up Surveys

The Third Economic Census was synchronized with the house listing operations of the Population Census 1991 on the same pattern as EC- 1980. The coverage was similar to that of EC-1980. All States/UTs except Jammu & Kashmir, where Population Census 1991 was not undertaken,were covered.Based on the frame thrown up by EC-1990 four follow up surveys were carried out:(i) Establishment Survey covering sectors of mining & quarrying, storage & warehousingin 1992-93;(ii) Establishment Survey covering sectors of hotels & restaurants and transport in 1993-94;(iii) NSS 51 st round covering directory, non-directory and own account establishments inunregistered manufacturing sector in 1994-95; and(iv) Directory Trade Establishments Survey in 1996-97. NSS 53 rd round covered theresidual part of the unorganised trade sector in 1997.
