Sampling
Sampling Procedure
For the 2014 SAS, NISR used as sampling method a dual frame sampling design combining selected area frame sample3 segments and a list of Large Scale Farmers. NISR used also imagery from RNRA with a very high resolution of 25 centimeters to divide the total land of the country into twelve strata.
A total number of 540 segments were spread throughout the country as coverage of the survey with 24,475 and 25,167 agricultural operators in Season A and Season B respectively. From these numbers of agricultural operators, sub-samples were selected during the Second Phases.
Furthermore, enumerated Large Scale Farmers were 498 in 2014 Season A and 502 in Season B. Season C considered 152 segments counting 7,684 Agricultural Operators from which 609 Agricultural Operators were selected for survey interviews.
During Phase I, a complete enumeration of all farmers having agricultural land and operating within the 540 selected Segments was undertaken and counted 24,475 and 25,167 agricultural operators respectively in Season A and B. Season C considered only 152 segments counting 7,684 Agricultural Operators.
Response Rate
The response rate for Seasonal Agriculture Survey is 98%.
Weighting
The sample weights were calculated for each district considering the total number of segments in each district and the sample size in the specific districts.
