Department of Census and Statistics (DCS) designed a Labour Force Survey (LFS) on a quarterly basis to measure the levels and trends of employment, unemployment and labour force in Sri Lanka on a continuous basis. This survey was commenced from the first quarter 1990 with USAID technical assistance and is being continued by the DCS. This report is based on a sample of 17,620 housing units, covering the entire country, province providing national, provincial and district level estimates with stipulated standard errors of labour force characteristics as reported in the relevant reference periods of each 9 months of the year 2011. This survey covers persons living in housing units only and, it excludes the institutional population. Under the prevailing situation in Northern Province, it was able to conduct the survey in that province successfully. So, after a long time, DCS could publish this report covering the whole country.
