A 2-part survey was conducted, the first part focused on the respondents' household as the unit of analysis, information was collected for up to 15 respondents, although most households had only 4 to 6 respondents. The second part of the survey focused on individuals, the respondent's position in the household and their personal background. In the Individual dataset, observations were collected for up to 15 of the respondent's siblings.
