Egypt - Harmonized Panel Survey of Young People in Egypt, Panel HSYPE 2009-2014

Sampling Procedure


----> Survey design and implementation
SYPE 2009 targeted young people aged 10-29, thus encompassing both "youth" and "adolescents. The SYPE team chose this age range in order to track young people throughout the complete duration of their transition to adulthood, allowing for an extended period to account for the phenomenon of delayed marriage and, in some cases, delayed transitions to productive work. The SYPE 2014 survey built a panel dataset by going back to re-interview the same sample of young people (now aged 13-35) interviewed in SYPE 2009 in all governorates of Egypt.

----> Survey sample
A brief explanation of the sampling design for the previous wave of SYPE is essential for understanding the 2014 SYPE sampling. SYPE 2009 is a uniquely comprehensive survey in that it is nationally representative, covering all the governorates in Egypt including the five frontier governorates, and was specifically designed for a priori inclusion of informal urban areas, also known as slums (or ashwaiyyat in Arabic). The Frontier Governorates and informal areas are often not covered in largescale surveys. The sample is designed so that the data are not only nationally representative, but also representative of Egypt's six major administrative regions: the Urban Governorates, rural Upper Egypt, urban Upper Egypt, rural Lower Egypt, urban Lower Egypt, and the Frontier Governorates.

The 2009 SYPE sample is a stratified, multi-stage cluster sample. Sampling was determined using primary sampling units (PSUs) drawn from the master sample provided by the Central Agency for Public Mobilization and Statistics (CAPMAS), which was based on the 2006 national census. SYPE 2009 consisted of 455 PSUs, with 239 PSUs in rural areas and 216 PSUs in urban areas. Rural PSUs were divided equally between large and small villages, in order to accurately represent the diversity of rural demographics and account for peri-urbanization.

Informal settlements were selected from a list developed by the Information and Decision Support Center of the Egyptian Cabinet of Ministers (IDSC). The 2009 SYPE data collection and processing were conducted in collaboration with the IDSC.

Out of the 11,372 households selected from the CAPMAS master sample for the 2009 SYPE sample, 20,200 young people were eligible to participate, and the Kish grid technique was used to draw a sample of 16,061 subjects from this pool of potential participants.

In total, 15,029 of the sampled 16,061 young people were interviewed, with attrition primarily being due to the individual's refusal to participate or unavailability during data collection periods.

SYPE 2014 sampled the same young people who were part of the original sample of 15,029 individuals surveyed in 2009. Of the 15,029 young people interviewed in 2009, data collectors managed to completely interview 10,916 (72.6%) aged 13-35 for the SYPE 2014 study (A few respondents reported being below age 14 at the time of the 2014 SYPE interview. These cases were left as is and included in the analysis, after carefully checking their exact age.) Every effort was made to track down the current contact information of households and/or eligible young people who had changed their location since the 2009 interview. During the SYPE 2014 data collection phase, a household was not interviewed (i.e., the household questionnaire was not filled out) if the eligible young person could not be located either in the original or in a split household.

Weights based on the probability of non-response were constructed to adjust the sample of the 2014 SYPE for attrition (Very few cases were reported as missing due to migration or death of an eligible young person. These cases were assigned to the "household not found" or "individual not found" categories. However, it is suspected that some of the households that were unable to be tracked in 2014 may also have been missing due to the migration or death of household members).

The harmonized sample includes the 10,916 individuals re-interviewed in 2014.

Deviations from Sample Design

Attrition was mainly due to family refusal to participate (9%) as well as the relocation of respondents (14%) who could not be tracked in 2014, 60% of the interviewed individuals were still in their original 2009 households, while 12.6% were found in split households (A split household is defined in this 2014 SYPE panel as a household that was formed due to the move of at least one eligible young person out of his/her original 2009 household to form a new household after the 2009 interview).

Response Rate

Of the 15,029 young people interviewed in 2009, data collectors managed to completely interview 10,916 (72.6%) aged 13-35 for the SYPE 2014 study.
Those represent the sample of the harmonized dataset.
