Sampling
Sampling Procedure
Employment and Earnings Survey 2013 sample was based on a sampling frame obtained from the Central Register of Establishments (CRE) maintained by the NBS. The existing sampling frame was developed on the basis of International Standard Industrial Classification Revision 4 (ISIC Rev.4). 10
Employment and Earnings Survey 2013 covered all establishments of public and all private sector establishments employing at least 50 employees. For all private sector establishments employing 5 - 49 employees, multistage sampling technique was used. The first stage within a region included stratification of all private establishments employing 5 - 49 employees into two strata namely 5 - 9 employees and 10 - 49 employees. Then, the sample size for each stratum was developed in each region. Finally, probability proportional to size (PPS) was used to draw the sample within each industry.
A similar approach was used in all the 25 regions to draw the sample size across all industrial major divisions in the two strata separately to enhance representation of all economic activities to the economy.

On average, the response rate was about 89.2% for Employment and Earnings Survey 2013.
Weighting
The sampling weights for the strata were calculated by using the simple expansion method denoted as:-
Weight = N/n
Where: N = Total number of establishments before sampling
n = Total number of sampled establishments
Variable weight was used in the data set to weight the data.
Weight = N/n
Where: N = Total number of establishments before sampling
