Labor Force Survey [hh/lfs]

Series Information

Sri Lanka Labour Force Survey (LFS) was designed to measure the levels and trends of employment, unemployment and labour force in Sri Lanka.

Since 1990, the survey is being conducted quarterly. 1992 is the third successive year in which the survey has been repeated. Up to 1992, twelve quarters have been completed at the rate of four surveys per year. The Quartely sample size is 2000 housing units through which national estimates ( excluding Nothern and Eastern provinces) are usually computed.

A nationally representative sample of about 10,080 housing units have been covered in this survey.

Amongst other figures, Provincial level estimates are taken from the Annual LFS 1992 data file which is a combination of all the four quarterly files processed for the year 1992.

Abstract

The employment/unemployment data are required at very short intervals to monitor the programs made in the employment generating policies of the government. To satisfy this need, Sri Lanka Labour Force Survey was designed as a quarterly basis survey to measure the levels and trends of employment, unemployment and labour force in Sri Lanka. Thus the survey is repeated four times each year since the first quarter of 1990.

Key objectives of the survey

To study the economically active / inactive population.
To analyze employment by major industry group and employment status.
To determine unemployment rates by level of education and by age group
To study the informal sector employment.
To determine the underemployment rates by sector and by major industries

Sampling

Sampling Procedure

A stratified two stage probability sample design is, used with census blocks as primary sampling units (PSU's) and housing units as secondary and final sampling units (SSU's).

National sample of approximately 20,000 housing units (excluding Northern and Eastern Provinces) were selected to provide reasonably accurate results at district level as well as national level.

Deviations from the Sample Design

The survey covered all parts of the Island excluding the Northern and the Eastern provinces

Weighting

Two stage sample design was used

(1) The probability of selecting the i-th psu(block)=p1
(2) The probability of selecting the j-th household ( in the i-th psu) =p2

           Overall probability (p) = no.of psu's (in the stratum(nh)) x p1 x p2
           Sample weight (Wh)=1/p
Final weight=Wh x non-response factor x population under coverage adjustment .

Survey instrument

Questionnaires

The survey was confined to the household sector and hence persons living in institutions such as Armed forces, Police barracks, hostels and boarding houses with more than 5 boarders were excluded from this survey.
