Thereafter, data on employment and earnings continued to be collected annually. However, due to lack of financial resources, this series was discontinued for sixteen years before it resumed in 2001, this report being the sixth since then.

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.
