The master sampling frame prepared for 2001  Census of Population and Housing was used as the sampling frame for the selection of sample for the labour force survey 2008.\n\n\n2.2 Sample size\n\nThe 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 estimates of district level. In 2004 again 20,000\nhousing 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. As such, in 2008, the annual sample of 22,500 housing units were selected.\n\n2.3 Sample Allocation\n\nAllocation of 2,250 Primary Sampling Units (PSU\u2019s) for the districts and sectors were done using the Neymann Allocation procedure which considers the variance of unemployment rate as usually. The allocated sample for each district then equally distributed among the 12 monthly rounds.

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 2,250 primary sampling units was selected from the sampling frame for the 2008 labour force survey.\n\n2.5 Selection 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 primary sampling unit 10 housing units (SSU) were selected for the survey.","sampling_deviation":"The field work of the survey for the year 2008 was done in all twelve months in 2008.

In year 2008 the\nsurvey was carried out in Eastern province successfully. Therefore, this report is based on a\nannual sample of 20,260 housing units, excluding only Northern province providing national,\nprovincial and district level estimates with a stipulated standard errors of labour force\ncharacteristics as reported in the relevant reference periods of each 12 months of the year 2008.\n\nThis survey covers persons living in housing units only and, it excludes the institutional population.","coll_mode":["Face-to-face [f2f]"],"research_instrument":"Survey Schedule\n\nCurrent survey concepts and methods are very similar to those introduced at the beginning of the survey in 1990.
