Sample size and design

Statistical unit

The reporting unit is the establishment, defined as a farm, estate, mine, factory, workshop, store, office, business place, restaurant, shop, etc., under single ownership or control, located at one place or contiguous area and engaged in one or predominantly one kind of economic activity.

Survey universe / sample frame

A complete list of establishments was available at the time of the first survey (1971), which was used as the sample frame. It was prepared on the basis of the listing of all buildings in the country at the time of the 1971 Census of Population and Housing. At that time, there were about 22,500 establishments with five or more paid employees. Thereafter, this list has been updated annually on the basis of the new registrations recorded on the lists of the Employees Provident Fund.

Sample design

The survey is a complete enumeration of establishments with five or more paid employees.

Field work

Data collection

This takes place in July of each year, by means of mailed questionnaires. The survey organization comprises the staff of the Statistics Division of the Department of Labour.

Survey questionnaire

One page of explanatory notes and definitions is provided along with the questionnaire.

Substitution of sampling units

Not relevant.

Data processing and editing

Data are edited and coded by hand at the Statistics Division, then entered onto a mainframe computer.

Types of estimates

The employment estimates are not weighted.

Adjustments

There is no adjustment for non-response.

Other bias
