A two stage sampling procedure was applied and the sample was stratified, clustered and selected to meet the requirement of probability sampling. The sample was based on the 1996 Population Census enumerator areas and the estimated number of people from the administrative records of the 1996 population Census. The sampled population excluded all prisoners in prisons, patients in hospitals, people residing in boarding houses and hotels (whether temporary or semi-permanent).\n\nThe data was explicitly stratified by province, Transitional Metropolitan Councils (TMC) and District Councils (DC). A square root method was used for the allocation of the sample EA's to the explicit strata.\n\nWithin each explicit stratum the EA's were stratified by simply arranging them in geographical order by magisterial district and within the magisterial district by EA. The allocated number of EA's was systematically selected with probability proportional to size in each stratum The measure of size was the estimated number of people. In each EA, a systematic sample of 10 households was drawn.","coll_mode":"Face-to-face [f2f]","research_instrument":"The data files in the October Household Survey 1997 (OHS 1997) correspond to the following sections in the questionnaire:\n \nPerson: Data from Section 1 and Section 4\nBirths: Data from Section 2\nWorker: Data from Section 3\nMigrant: Data from Section 5\nDeaths: Data from Section 6\nMigration of head: Data from Section 7\nDomestic: Data from Section 8","weight":"The 1996 population Census was used as a basis for the weighting.\n\nHousehold weights were calculated by using the reciprocal of the inclusion probabilities.\nSince the sample selection was done in two stages (i.e. first stage - selection of an EA,second stage - selection of a household in the selected EA):\n\nThe inclusion probability of an EA (say p1):\n\nSince this was done with probability proportional to size (size being the number of persons residing in the EA),\n\np1 = m .
