The sample process consisted of the following steps:
Selection of targeted population (people in the age bracket 60+)
Targeted population was estimated to be 9.2 percent of the total population (around 1.5 million).
Selection of districts
North-Eastern provinces were excluded, and among other districts, 13 districts were covered out of the 17 districts (districts with escalating tensions arousing from the ethnic conflict were excluded - see below the selection of districts).
Random selection of 260 Primary Sampling Units (PSU), based on the 2001 census of housing and population framework in the urban, rural and the estate sector.
Obtaining basic personal information on household members in all households in selected PSU ("listing exercise").
Random selection of secondary sampling units (households), based on completed the listing results, by DCS. In each PSU, 10 households (Secondary Sampling Units) were selected.
The listing exercise started in October 2005 and was completed by the end of December 2005.
