Social and Health Status and Educational Achievement of Adolescents 1998

Sample Design and Implementation

The survey sample is a nationally representative, multistage, stratified, probability cluster sample of adolescents. In the first stage, 101 primary sampling units (PSUs) were selected proportional to population size using the updated census frame compiled by the Central Agency for public Mobilization and statistics. Only the five frontier governorates were excluded from the study, as only about 1.5 percent of the total population of Egypt lives in these five governorates.

The PSUs were stratified by 21 governorates and by urban /rural location within each governorate.
The total sample size was 13,271 households. All these households were screened using a household roster sheet .

Eligible households were then defined as households with at least one member in the age range 10-19 years. The number of eligible households amounts to 7,256. Using the Kish grid, one adolescent (by gender)was randomly selected from each eligible household. This resulted in one boy and one girl being selected from households that contained at least adolescent of each gender. A total of 9,128 adolescents were successfully interviewed (4, 354 boys and 4,774 girls). The number of pairs of siblings successfully interviewed was 2,413. All randomly selected adolescents were eligible for an individual interview using a core instrument. The sample of adolescents is not self-weighted.
