Urban, rural and estate sectors of the District are the domains for stratification. The sample frame is the list of buildings that  were prepared for the Census of Population and Housing 2012.\n\nSelection of Primary Sampling Units (PSU's) \n\nPrimary 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 25000 primary sampling units was selected from the sampling frame for the survey.\n\nEach selected block was updated to include newly built housing units and excluded demolished housing units, which are no longer in  existence. This updating operation was also carried out over a period of 12 months, starting from july 2012 to june 2013. For each PSU, updating was done about one month prior to the scheduled interviewing.\n\nSelection of Secondary Sampling Units (SSU's)\n\nSecondary Sampling Units are the housing units in the selected 2500 primary sampling units (census blocks). From each primary sampling unit 10 housing units (SSU) were selected for the survey. The total sample size of 25000 housing units was selected and distributed among Districts in Sri Lanka.","coll_mode":["Face-to-face [f2f]"],"weight":"http:\/\/www.statistics.gov.lk\/HIES\/HIES2012PrelimineryReport.pdf\n\nBy visiting the above website a description about the adjustments  for  non-response  could be read in section  1.4  of  the preliminary  report."}}},"schematype":"survey"}
