Labor Force Survey [hh/lfs]
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. 1997 is the eighth successive year in which the survey has been repeated.
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 1997 data file which is a combination of all the four quarterly files processed for the year 1997.
The employment/unemployment data are required at very short intervals to monitor the program 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

Data are collected quarterly during a similar time period (eg every third week of the quarter) in each quarter through a scientifically selected sample designed to represent the non-institutional household population. About 4000 households are visited each quarter. Respondents are interviewed to obtain information about each member of the household whose age is 10 years or over.
The inquiry relates to the previous calendar week of the interview to obtain "current" information, and to the previous 12 calendar months to obtain "usual" activity information.
[Inmates of institutions, military camps, and lodgings are not surveyed. Households with more than 5 lodgers and boarders were excluded from the survey.]
