Sampling
Sampling plan and the sampling frame
Two stage stratified sampling procedure is adopted to select a sample of 25,750 housing units to be enumerated at the survey. The sampling frame prepared for 2012 Census of Population and Housing is used as the sampling frame for the sample selection of LFS in 2016.
Sample size
At the beginning in 1990, the sample size was 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. In 1992 and 1997, an annual sample of 20,000 housing units was selected to give reliable estimates by district level. 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 from 2006 to 2010. From 2011 onward annual sample of 25,000 housing units were selected. In 2016, both Labour Force & Household Income and Expenditure Surveys were conducted parallely using same sample therefore the optimal sample size is 25,750.
Sample Allocation
In 2016, 2575 Primary sampling Units (PSUs) were allocated to each district and to each sector (Urban, Rural and Estate) by using the Neymann allocation method which considers the variance of unemployment rate as usually. The allocated sample for each district then equally distributed for 12 months.
Selection of Primary Sampling Units (PSU)
Primary sampling units are the census blocks prepared at the Census of Population and Housing - 2012.
Selection of Secondary Sampling Units (SSU)
Secondary Sampling Units are the housing units in the selected 2575 primary sampling units (census blocks). From each selected primary sampling unit, 10 housing units (SSU) are selected for the survey using systematic random sampling method.
Please refer page number 6 of annual report for weighting procedure.
