APPENDIX B

SAMPLE DESIGN

The major objective of the Demographic and Health Survey was to provide estimates with acceptable precision for important population characteristics such as fertility, infant and child mortality, and contraceptive prevalence and for key maternal and child health and nutrition indicators. In addition, women's status measures were desired for a subsample of the women interviewed in the EDHS-95, and two govemorates in Upper Egypt were to be oversampled for a panel study of the reasons for nonuse of family planning in Egypt.

B.1 Sample Design

The sample selection for the EDHS-95 was designed to obtain estimates of the required population, health and women's status indicators for the country as a whole and for six major administrative regions (the Urban Govemorates, urban Lower Egypt, rural Lower Egypt, urban Upper Egypt, rural Upper Egypt, and the Frontier Govemorates~). Further, the sample selection for the EDHS- 95 allows for estimates of most key variables, with the exception of fertility and mortality rates and women's status indicators, at the governorate level in the Urban Govemorates, Lower Egypt, and Upper Egypt. In the latter region, the design also called for Assuit and Souhag govemorates to be oversampled in order to provide sufficient cases for the panel study of the reasons for nonuse of family planning in those areas. As a result of the oversampling, it is possible to obtain reasonably precise estimates of fertility rates for these two govemorates in addition to the other variables. However, the size of the samples in these two governorates is not large enough to provide child mortality estimates. Finally, in the Frontier Govemorates, the sample size for individual govemorates is not sufficiently large to allow for separate governorate-level estimates. However, separate estimates are possible for the western Frontier Govemorates (Matrouh and New Valley) and the eastern Frontier Govemorates (North Sinai, South Sinai and ).

In order to meet the objectives of the EDHS-95 sample, the target sample was set at 14,000 interviews with ever-married women age 15-49. It was estimated that 16,000 households had to be selected for the EDHS-95 sample in order to yield the desired number of interviews. Table B.1 presents the distribution of the target sample and the overall sampling fractions by govemorate.

B.2 Sample Frame

For each governorate, a list of shiakhas and towns served as the initial sample frame for urban areas, and a list of villages constituted the frame for the rural areas. The lists, which were based on the administrative units from the 1986 census, were compiled from the frames that were used for the EDHS- 92 survey. The lists were updated to take into account newly defined shiakhas or villages (created either by division, grouping or reclassification of units).

B.3 Sample Selection

A total of 467 primary sampling units (PSUs) were selected with probability proportional to the size of the unit. As Table B.1 shows, 204 of these units were in urban areas and 263 in rural areas.

i The Frontier Governorates were not included in the 1988 and 1992 DHS surveys.

225 Before implementing this selection, the list of shiakhas or villages were arranged in serpentine order from the northwest comer of the governorate to the southeast comer. Shiakhas or villages with less than 2,500 population were generally grouped with contiguous shiakhas or villages until the minimum size was obtained.

A list of the selected PSUs allocated according to govemorate and sector (urban/rural) is shown in Table B.2. Figures B.I.I-B.1.4 show the geographical distribution of the sample.

Following the selection of the shiakhas and villages, detailed maps were obtained for the selected units. The map for each unit was divided into a number of parts (with equal size). In the case of most PSUs, one part was then selected systematically with equal probability. A quick count was carried out to divide the part into standard segments of about 100 households. Two segments were then selected systematically with equal probability.

For shiakhas or villages in which there were 4,000 or more households (approximately 20,000 population), the selection procedures were modified slightly. Two parts were selected from these large units. A quick count was carried out to divide each part into segments of around 100 households, and one segment was selected from each part.

A household listing operation was implemented in each of 934 segments selected for the EDHS-95 sample. Based on the household listing, the household selection was implemented in such manner as to obtain a self-weighting sample within each governorate. However, the number of households selected from each governorate is disproportional to the govemorate's share of the national population. As a result, the EDHS-95 sample is not self-weighting at the national level.

Finally, a systematic subsample of one-third of the household sample was selected for the women's status survey in 24 of the 26 govemorates. In Assuit and Souhag governorates (which were targeted for a special panel study), all of the selected households were included in the women's status subsample.

B.4 Results of the Sample Implementation

Results of the sample implementation for the EDHS-95 survey are shown in Table B.3. The household and women's response rates exceeded 98 percent in all areas.
