India - Annual Survey of Industries 1984-85

Sampling Procedure

The sampling design followed in ASI 1984-85 is a stratified unistage with StateXNIC 3 digit as stratum. All the factories in the updated frame (universe) are divided into two sectors, viz., Census and Sample.

a) CENSUS : The Census sector comprised of all big units with 50 or more workers and using power or 100 or more workers without using power and all electricity undertakings. All industrial units belonging to the 12 less industrially developed states/ UT's like Goa, Himachal Pradesh, J & K, Chandigarh, Manipur, Meghalaya, Nagaland, Tripura, Daman & diu, Pondicherry Dadra & Nagar Haveli, and Andaman & Nicobar Islands etc. were also enumerated every year along with the census units.

b) The rest of of the universe was covered on sampling design adopting State X 3 digit industry group as stratum so as to cover all the units in a span of two consecutive years (50% samples in alternate years).

*****Multiplier : How to apply the Multiplier :

(i) If Scheme Code = 1 then Multiplier = 1
If Scheme Code = 2 then Multiplier = 2

(ii) During Processing/Tabulating apply the multiplier to each characteristics.

****


There was no deviation from sample design in ASI 1984-95


(i) If Scheme Code = 1 then Multiplier = 1
If Scheme Code = 2 then Multiplier = 2

(ii) During Processing/Tabulating apply the multiplier to each characteristics.
