Sampling
Sampling Procedure
Sampling Procedure
The sampling design followed in ASI 1993-94 is a circular systematic one. All the factories in the updated frame (universe) are divided into two sectors, viz., Census and Sample.
a) CENSUS : To keep pace with the enormous growth of the factory sector, definition of the census sector was changed from ASI 1987-88 to the units having 100 or more workers irrespective of their operation with or without power and all electrical undertakings. All industrial units belonging to the 12 less industrially developed states/ UT's viz. Manipur, Meghalaya, Nagaland, Tripura, Sikkim and Andaman & Nicobar Islands etc.
b) The rest of of the universe was covered on sampling basis so as to cover all the units in a span of three years. In any stratum, if the number of units was less than 20, then the entire stratum was enumearted completely along with census factories. In any stratum if no. of unit is between 21 & 60, a minimum sample of size 20 was selected by Circular Systematic Sampling. For all other units a uniform sampling fraction of 1/3 was adopted.
Deviations from Sample Design
There was no deviation from sample design in ASI 1993-94
Weighting
The multiplier is calculated for each stratum (i.e. State X NIC-04 (4 Digit) after adjusting for non-response cases.
HOWEVER, IT IS TO BE NOTED THAT ALL THE INDUSTRIES (RECORDS) ARE ALREADY WEIGHTED BY MULTIPLIER FACTOR.
