SAMPLE DESIGN APPENDIX B The major objective of the 2000 Egypt Demographic and Health Survey sample design was to provide estimates with acceptable precision for key demographic characteristics such as fertility, infant and child mortality, and child health indicators. The sample was designed to provide these estimates at the national level, for urban and rural areas, and for six main residential categories: Urban Governorates, urban Lower Egypt, rural Lower Egypt, urban Upper Egypt, rural Upper Egypt, and the Frontier Governorates. In addition, the sample design allows for estimates of the contraceptive prevalence rate and other basic health indicators, but not fertility and mortality rates for each of the 21 governorates in the Urban Governorates, Lower Egypt, and Upper Egypt.1 In the Frontier Governorates, the sample size for the individual governorates is not sufficiently large to allow for separate governorate level estimates. To achieve the above objectives, a three stage probability sample was designed. The following is a detailed description of the 2000 EDHS sample design. A description of the field activities involved in the implementation of the sample design is included in Chapter I of this report. B.1 SAMPLE DESIGN The main concern in developing the sample design for the 2000 EDHS was to secure a sufficient number of cases in each domain in order to reduce sampling error and provide estimates of adequate precision for the purposes of the survey. Sampling error has two components, one corresponding to the variation between primary sampling units (PSUs) and the other to the variation within PSUs, with the major component usually being the variation between PSUs. Thus, the total number of PSUs is an important factor in controlling the size of the sampling error since the variation between PSUs depends on this number, i.e., generally the smaller the number of PSUs, the greater will be the variation. The DHS sampling policy recommends a minimum of 1000-1200 women per domain. This number of cases allows for a reasonably precise estimate of the total fertility rate for the domain. Thus, given an optimal sample take of about 30 cases per PSU, a minimum of 40 PSUs were required per each of the six major areal domains and 33 PSUs for the Frontier Governorates in order to meet the demands for regional estimates. As noted above, however, the 2000 EDHS sample had to be selected in such fashion as to also allow for estimation of contraceptive prevalence rates and other basic health indicators for 21 separate governorates. DHS sampling policy recommends that minimum of 450 completed interviews with eligible women be obtained to provide reliable estimates of these types of variables. This principle was used in determining the size and distribution of the target sample for the 2000 DHS presented in Table B.1 by governorate. 1 Egypt is divided into 26 govern orates. R ecently Luxor originally a pa rt of Qena go verno rate has been given a new status as a separa te adm inistrative unit. Like the Frontier Governorates, Lux or h as a relatively sm all population in com parison to the other governorates. Therefore, for the purposes of establishing the frame for the selection of the 2000 DHS, Luxor was combined with Qena governorate.

The Central Agency for Public Mobilization and Statistics provided the required population information for each of the administrative units in the frame based on 1996 Population Census. The frame was updated taking into consideration administrative changes that had taken place since the census. 220 * Appendix B B.3 SAMPLE SELECTION A total of 500 primary sampling units (PSUs) were selected from the 26 governorates with probability proportional to the size of the unit. Of these, 228 units were in urban areas and 272 units in rural areas (Table B.1). Before the selection of PSUs, the frame within each governorate and residential category (urban/rural ) was arranged in serpentine order, beginning from the northwest corner of the governorate. Shiakhas or villages with less than 2,500 population were grouped with contiguous shiakhas or villages until the minimum size was obtained. Table B.2 shows the list of the selected PSUs allocated according to governorates and urbanrural location. Figures B.1.1-B.1.4 show the geographic distribution of the sample. Detailed maps were obtained for the selected PSUs. The map for each unit was divided into a number of equal-sized parts, with each part including approximately 5,000 population. One part was then selected systematically with equal probability from most of the PSUs. A quick count was then carried out to divide the selected part into standard segments of about 200 households. Two segments were then selected from each part, with probability proportional to the estimated number of housing units at the quick count stage. For shiakhas (villages) in which there were 4,000 or more households (approximately 20,000 population), the selection procedures were modified slightly. Two parts were selected systematically with equal probability from these large units. A quick count was carried out to divide each part into segments of around 200 households. One segment was then selected from each part systematically with probability to the estimated number of housing units at the quick count. A total of 1,000 segments were selected in this stage. A household listing operation was implemented in each of selected segments. Based on the household listing, a systematic random sample of households was selected from each segment in a manner as to obtain a self-weighting sample within each governorate. However, the number of households selected from each governorate is disproportional to the governorate's share of the national population. Accordingly, the 2000 EDHS sample is non-self-weighting at the national level. Finally, a systematic sub-sample of one half of all households was selected for the anemia testing. All ever-married women, children under age six, and adolescents 11-19 years in the households of the subsample were eligible for the anemia testing. B.4 SAMPLE IMPLEMENTATION Results of the sample implementation are presented in Table B.3. The results indicate that 17,521 households were selected for the 2000 EDHS sample. The EDHS field staff successfully interviewed 16,957 of the sample households, for a response rate of 99 percent. In the interviewed households, 15,573 eligible women were interviewed with a response rate 99.5 percent. This gives an overall response rate of 99 percent.
