Abstract
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 (in most years) 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
In January 2006, significant improvements have been made to the survey schedule in such aspects as literacy, household economic activities, informal sector employment, underemployment etc. The survey covered all 25 districts in 2013.

Sampling
Sampling Procedure
2.1 Sampling plan and the sampling frame
A two stage stratified sampling procedure was adopted to select a sample of 25,000 housing units to be enumerated in the survey. The master sampling frame prepared for 2012 - Census of Population and Housing was used as the sampling frame for the selection of sample for the Labour Force Survey 2013.
2.2 Sample size
The quarterly survey was conducted since 1990 using a sample of 2,000 housing units per quarter in areas other than North and East, and the sample size was increased to 4,000 housing units per quarter in 1996 and continued thereafter. However, in 1992 and 1997, an annual sample of 20,000 housing units was selected to give reliable district level estimates. In 2004 again 20,000 housing units were selected for the survey. However, in order to provide district level estimates precisely, it was decided to use 20,000 - 25,000 housing units as the annual sample. As such, in 2013, the annual sample of 25,000 housing units was selected.
2.3 Sample Allocation
Allocation of 2,500 Primary Sampling Units (PSU's) for the Districts and sectors were done using the Neymann Allocation procedure. In other words, the allocation of PSU's to strata was disproportionate, designed to produce estimates of acceptable reliability for each area for which separate estimates were needed. Then The District sample was equally distributed among the 12 monthly rounds. Table 1 gives the sample distributions by District for year 2013.

2.4 Selection of Primary Sampling Units (PSU)
Primary sampling units are the census blocks prepared for the Census of Population and Housing - 2012. The sample frame, which is a collection of all census blocks in the domain, was used for the selection of primary sampling units. A sample of 2,500 primary sampling units was selected from the sampling frame for the 2013 labour force survey.
2.5 Selection of Secondary Sampling Units (SSU)
Secondary Sampling Units are the housing units in the selected 2,500 primary sampling units (census blocks). From each primary sampling unit 10 housing units (SSU) were selected for the survey.

Questionnaires
In the beginning of January 2006, some significant improvements were made to the labour force survey schedule in order to fulfill the requirements of it's users and also to provide additional information for the planning purposes. This was
done after carefully reviewing of the LFS schedule with the Assistance of Economic and Social Commission for Asia and the Pacific (ESCAP) Adviser. The revision was made focusing on literacy, household economic activities, informal
sector employment and underemployment etc. This revised version was introduced for the survey conducted in 2006 first quarter, and it will be used in future as well.
