The master sampling frame prepared for 2001 \u30fbCensus of Population and Housing is used as the sampling frame for the selection of sample for the labour force survey 2009. This main frame was updated after the Tsunami \nincident in 2007 using quick count method. \nSample size\nThe quarterly survey has been conducting 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 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 \u30fb25,000 housing units as the annual sample from 2006. As such, in 2009, the annual sample of 22,500 housing units were selectedSample AllocationIn 2022, 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. \n\nIn 2009, 2250 Primary sampling Units (PSU) are allocated to each district and to each sector by using the Neymann allocation method which considers the \nvariance of unemployment rate as usually. The allocated sample for each district then equally distributed among 12 months.\n\nSelection of Primary Sampling Units (PSU) \n \nPrimary sampling units are the census blocks prepared at the Census of Population and Housing - 2001. The sample frame, which was updated after Tsunami has been used for the selection of primary sampling units. \n\nSelection of Secondary Sampling Units (SSU) \n\nSecondary Sampling Units are the housing units in the selected 2,250 primary sampling units (census blocks). From each selected primary sampling unit 10 housing units (SSU) are selected for the survey using random sampling method.","coll_mode":["Face-to-face [f2f]"],"research_instrument":"Survey Schedule \nCurrent survey concepts and methods are very  Similar to those introduced at the beginning.
