National Sample Survey

 The National Sample Survey Office (NSSO) was set up in 1950, with the idea of having a permanent survey organization to collect data on various facets of the economy. In order to assist in socio-economic planning and policy making, NSSO conducts nationwide sample surveys known as National Sample Survey (NSS). The NSS is a continuing survey in the sense that it is carried out in the form of successive “rounds”, each round usually of a year's duration covering several topics of current interest. The surveys are conducted through household interviews, using a random sample of households covering practically the entire geographical area of the country.

Participation of State

As the NSS samples were small, the state governments were invited to participate with matching samples so as to enable the preparation of estimates at sub-state level which was not possible with the ‘Central Sample’ alone. Considering the demands for district level estimates, Economics and Statistics Department of Kerala has been participating in the National Sample Surveys from the very beginning with matching samples to provide more disaggregated results at district level by pooling of central and state sample data.

 Subject Coverage of NSS

The National Sample Survey covers the same topics / subjects at certain regular interval. Of course, the designing of schedule will be modified according to the changed needs. According to the NSSO the long term programme for its coverage is as under:

1.  Population, births, deaths, disability, morbidity, fertility, maternity and child care and family planning. - Once in ten years

2. Debt and Investment and capital formation - Once in ten years

3. Land-holdings and livestock enterprises - Once in ten years

4. Employment and employment and Consumer Expenditure - Twice in ten years.

5. Unorganized enterprises in non-agricultural sectors - Twice in ten years.

 

Source of Data and Methodology

                Entire programme of every round of survey is being designed by the NSSO. After pre-test and expertise discussion on the instruction to the field agency and formats of schedules to be canvassed in depth the survey programme of the year is released in its final shape. The central and state agencies are doing their field work independently with the samples allotted separately for Centre and State. DES collects the basic data from State sample through its own field investigators. The questionnaires, concepts, definitions etc. used are the same as those of NSSO used in the Central sample. 

Data processing

                 After completing the field work of each round, the schedules are scrutinized in district offices and headquarters by the officers of the NSS units in the District Offices and in the DES Headquarters. Then data entry, data validation and table generation are done with the software provided by NSSO. On the basis of estimates derived from state sample data, the report is prepared.

 Current Round

               NSS 77th round (January 2019 to December 2019) is earmarked for collection of data on two subjects “Land and Livestock Holdings of Households and Situation Assessment of Agricultural Households” and “Debt and Investment”. The last survey on these subject was conducted in 70th round of NSS (January 2013 to December 2013).

This survey will be conducted in 152 selected Panchayat wards and 152 selected urban areas of Kerala by Economics and Statistics Department .The same number of Panchayat wards and urban areas will be covered independently by National Sample Survey Office Under Ministry of Statistics and Programme Implementation, Govt.of India.

This survey period is divided into two phases, namely Visit 1 and Visit 2. The period of the first visit (i.e. Visit 1) will be January – August 2019 (duration of eight months) and that of the second visit (i.e. Visit 2) will be September – December 2019 (duration of four months). The reference period for the survey would be the Agricultural year (July 2018 to June 2019). Information for the period July 2018 – December will be collected in Visit 1 and the information for the second period i.e. January 2019 – June 2019 will be collected during Visit 2

The survey on Land and Livestock holdings of Households and Situation Assessment of Agricultural Households will be conducted in the rural areas only. The survey is aimed at generating different indicators of ownership and operational holdings of rural households, including their ownership of livestock and various estimates related to the situation of agricultural households such as indicators of (i) economic well-being as measured by their consumption expenditure, income, productive assets and indebtedness, (ii) their farming practices and (iii) awareness and access to various technological developments and welfare schemes in the field of agriculture. The survey will collect detailed information on receipts and expenditure of the agricultural households, farm and non-farm businesses and receipts from   all other economic activities pursued by their members so as to arrive at an estimate of average monthly income per agricultural household. These statistical indicators are required for planning, policy formulation and decision making at various levels within government and outside. The results will be of use to the Department of Agriculture, Cooperation and Farmers Welfare, Department of Animal Husbandry, Dairying and Fisheries, Commission for Agricultural Cost and Prices (CACP), National Accounts Division, etc. The results will also be used by various researchers and policy makers.

The objectives of the “Debt and Investment Survey” remain the same as those of the earlier surveys, namely, to obtain quantitative information on the stock of assets, incidence of indebtedness, capital formation and other indicators of the rural/urban economy which will be of value in developing the credit structure in particular, and will also be required in other areas of planning and development. Further, since the survey will be a sequel to the NSS 70th round “Debt and Investment Survey”, it is necessary to plan the survey in such a way as to ensure, as far as possible, comparability of its estimates with those generated from the earlier round.
