INDIA - Annual Survey of Unincorporated Sector Enterprises (ASUSE) of 2022-2023

Outline of sample design: A stratified multi-stage sampling design will be adopted for ASUSE.

Rural sector: The first stage units (FSU) will be the census villages in the rural sector. For rural part of Kerala, Panchayat wards (PW) will be taken as FSUs.

Urban sector: The First Stage Units (FSU) will be the latest updated UFS (Urban Frame Survey) blocks.

The Ultimate Stage Units (USU) will be establishments for both the sectors. In the case of large FSUs, one intermediate stage of sampling will be the selection of three hamlet-groups (HGs)/sub-blocks (SBs) from each of the large FSUs.

Sampling frame to be used for selection of FSUs

Census 2011 list of villages will be used as the sampling frame for rural areas. Auxiliary information such as number of workers, etc. available from Sixth Economic Census (EC) frame will be used for stratification, sub-stratification and selection of FSUs, for rural areas (except Kerala). In rural areas of Kerala, list of Panchayat Wards (PW) as per Census 2011 will be used as sampling frame. For all urban areas, the latest updated list of UFS blocks will be the sampling frame.

Stratification of FSUs:

Rural sector: Each NSS State region will constitute a rural stratum.

Urban sector: In urban areas, strata will be formed within each NSS State region on the basis of population of towns as per Census 2011. The tentative stratum numbers and their composition (within each NSS State region) will be as follows:

stratum 1 : all towns with population less than 50,000
stratum 2 : all towns with population 50,000 or more but less than 3 lakhs
stratum 3 : all towns with population 3 lakhs or more but less than 10 lakhs
stratum 4, 5, 6, ... : each city with population 10 lakhs or more


About 16500 FSUs will be covered for the central sample at all-India level.
