Although this is a national level survey, coverage of Nothern and Estern provinces was not at a sufficient level of response due to the prevailing situation in this area.
The coverage was also limited because of the fact that there was no complete list of establishments for the whole country at the time of the survey.
The survey covered establishments with five or more paid employees in private sector and also semi-government institutions in public sector.

A complete list of establishments ( survey frame ) was available at the time of the first survey started in 1971. This list was compiled along with the list of buildings in the country prepared for the Census of Population and Housing 1971. There were about 22,500 establishments with 5 or more paid employees and thereafter this survey frame was updated annually, taking new registrations from the Employees Provident Fund lists.
Construction of indices:
Index numbers of employment are calculated with 1971 as the base year, and using the link relative method. Indices are computed for each major industry division,
Weighting of sample results:
The employment estimates are not weighted
Non response : there are no adjustments for non response
Other bias : no adjustments have been made for any other bias.
Use of bench mark data : none
Seasonal variations : not relevant
Indicators of reliability of the estimates :
Coverage of the sampling frame : coverage is limited, as there is no complete list of establishments for the whole country.
Sampling error/Sampling variance : not relevant
Non response rate :
Non sampling errors : the main known source of bias is the limited coverage of the survey due to the lack of a complete list of establishments for the whole country.
Deviations from the Sample Design
The coverage of the survey was badly affected due to the limiting factors such as the non availability of a complete list of establishments for the whole country and the nature of the method of data collection (postal survey method).

An edit program was run to edit the raw data files.
Depending on the absence or presence of errors, the records in the raw data file were seperated into an error free file and a rejects file respectively. From the rejects file, a error report was generated indicating the reason for rejection of each record. The errors were checked and manually corrected on the report by referring to the questionnaire. Based on the corrected report, error records were updated by data entry operators.
The edit program was run again to edit the rejects file and the error free records were added to the error free file. If the rejects file was not empty the edit process was repeated.
