2.2 Sampling Weights for Households Household sampling weights were obtained from multiplication of inverse of selection probabilities at various sampling stages. In this case we had four sampling stages. Household sampling weights were thus obtained by the formulae mentioned below. Household Sampling = weights 2.3 Sampling Weights for household members aged 15 – 65 years-old Probability (FSU) -1 * Probability (SSU) -1 * Probability (TSU) -1 * Probability (Household) -1 Once the sample has been selected, one respondent aged 15 – 65 was selected per household by using Kish selection grid. With this method, all eligible individuals (aged 15 – 65) in a household had an equal chance of selection. One eligible respondent per household was selected. , Post-stratification was done under second level sub-strata by gender and age groups (15 – 24 years, 25 – 34 years, 35 – 44 years, 45 – 54 years and 55 – 65 years) to get reliable estimates for each age group by gender (demographic group)considering differences in their behaviors. The “Household Sampling Weights” were basis for calculation of sampling weights for target household members of aged 15 – 65 years old. First, we estimated total population of each gender by age group for each strata up to second level sub strata using household sampling weights. Second, we counted number of respondents we sampled for the survey at that level. Sampling Weights for household members aged 15 – 65 years old can be obtained by formulae mentioned below.
