Sampling
Sampling Procedure
Sample Design and Sample Allocation
There has not been any major change in the sampling strategy of ASI 2009-10 from that of ASI
2008-2009. The Census Sector has been defined as follows:
a) All industrial units belonging to the six less industrially developed states/ UT’s viz. Manipur,
Meghalaya, Nagaland, Sikkim, Tripura and Andaman & Nicobar Islands.
b) For the rest of the twenty-six states/ UT’s., (i) units having 100 or more workers, and (ii) all
factories covered under Joint Returns.
Strata (State by 4-digit of NIC-04) having less than or equal to four units after selecting the
Census Sector units as defined above are also selected as census sector.
From the remaining frame, samples were drawn considering a uniform sampling fraction of
19% for the states within a State X 4-digit NIC with a minimum of 4 units evenly distributed in two
sub-samples. The size of the live frame containing units with status ‘open’, ‘close’ or ‘non-operating’
was 2, 08, 417. 23,782 of these units belonged to the census sector, while the remaining 1, 84,635
units were from sample sector. Total sample size for ASI 2009-10 was 61,080 (23,782 census and
37,298 sample).
Deviations from Sample Design
There was no deviation from sample design in ASI 2009-10.
