Sampling units in towns, villages and refugee camps were selected according to simple random sampling from within a list that includes all Palestinian population concentrations. The selection was carried out in accordance to the population size of these concentrations. Each concentration was divided into units comprising one thousand people each. If a population concentration has a population of 10,000, then it is assigned ten units, accordingly it has ten chances of being randomly selected.
Sixty interviewers were then assigned to primary sampling units. Each of the interviewers was instructed to interview not more than twenty respondents. Households were selected according to a pre-defined route. Respondents were selected from within the households according to a Kish table that is an objective procedure for selecting household members. In case a respondent was not available during the interviewers’ visits, an appointment was made for a second visit.
West Bank Refugee Camps were over-sampled by 70 people in order to ensure sufficient cases for a deeper analysis of this group. The results presented hereafter are weighted to be representative of the whole Palestinian population*.
Following the donors’ request, all the results presented in the remainder of this report will be analysed in terms of:
The first two variables could have been combined into one category.
In that case, however, some subgroups would have become too small for analysis
(for example: non-refugees in camps). As such, it was thought more appropriate
to analyse the variables of “place of residence” and “refugee status” separately.
Results were systematically tested for statistical significance at a
95% confidence level. If no differentiation is shown or mentioned, this
means that there was none.
