of the Bureau is the provision and analysis of demographic data pertaining to the Palestinian population both here and elsewhere   A great deal of effort is being devoted at PCBS to institute a program on population statistics that provides such data  There has been no Census in the Remaining West Bank and Gaza Strip since 1967  The available demographic data are therfore incomplete and lack credibility when checked for consistency as shown in a recent PCBS publication In order to fulfill its responsibilities with regard to demographic information the PCBS has conducted a fairly large demographic survey in the West Bank and Gaza Strip during April-July 1995  This report presents preliminary findings from this study  for the Remaining West Bank and Gaza Strip Results partaining to Jerusalem will be published in forthcoming reports\nInitial Planning for this project began in early 1993 with backing from the PLO at that time  The project has as its  main objective the provision of basic demographic indicators at both the national and district levels  Other purposes of the project include  Preperation of a master sample frame to be used for drawing household samples until the

The two elements are usually closely interrelated, and determine the quality or reliability of survey estimates.  In this section both elements will be described briefly.  A more detailed description is provided in a separate working paper (Abu Hassan and Tamsfoss 1995).\n\nThe sample design adopted is a stratified three stage design for selection of households to be surveyed.  At the first stage a sample of localities was selected.  The sample localities have been subdivided into cells of approximately equal size, and a number of cells were selected randomly from each of the sample localities at the second stage.  At the third and final stage, a sample of households was selected from the sample cells.  For all the demographic variables included in the survey, records were taken for all members of the sample household.\n\nAlthough a two-stage design would have been preferable, the present, more complex one is partly an outcome of limited availability of data on which sample designing usually is based, specifically data on the population size of various small area units, e.g.  cells.  The sample designing was undertaken in parallel with the updating of maps for the localities in the West Bank and Gaza Strip during the winter and spring 1995 - another ongoing PCBS project.  Due to the limited time available, the design had to be completed before a complete set of updated locality maps was ready, implying the small area information needed was available for only a limited number of localities.  However, the map updating was coordinated with the sample designing in such a way that once the first stage sample of localities was selected, mapping of these localities was given highest priority, thus offering an opportunity to subdivide sample localities into cells with a known measure of (population) size.\n\nThe present design is based on  listings of localities provided by Barghouti  and Daibas (1993) for the West Bank, and  Abdeen and Abu-Libdeh (1993) for the Gaza Strip.  Even though the population figures are rough estimates as per 1992-93, produced mainly by questioning local administration informants (e.g.  Mukhtars) about the number of families in the locality, or projected estimates, they appear to be fairly well attuned with other sources (e.g.  Benvenisti and Khayat 1988).  Furthermore, the listings applied as a frame comprise more localities than previous ones, and should thus be more complete.  However, the coverage may still be less than - although close to - 100% in terms of areas.\n\nThe first stage comprises the assigning of localities (as listed by Barghouti and Daibas 1993; Abdeen and Abu Libdeh 1993) to be the Primary Sampling Units (PSUs), the stratification of the PSUs, and the selection of sample PSUs from each stratum.  The stratification is a subdivision of the PSUs according to district, administrative status of the locality, and estimated population (households) size.  The PSUs were selected independently for each stratum, and with probability proportionate to estimated population size.  In the Gaza Strip all localities were selected.  The same applies to the district capitals, municipal localities and refugee camps in the West Bank, except in two strata in A Ramallah district.  Whenever all PSUs in a stratum are selected, the design is a two stage one, and each single PSU is to be regarded as a separate substratum.  The two stage design also applies for several of the small villages (single cell localities).  As a matter of fact, the major parts of the sample is selected in two stages only, contributing favorably to smaller sampling error as compared to a strict three stage design.   \n\nThe second stage subdivision of sample PSUs into cells (or Secondary Sampling Units - SSUs) was done on maps indicating location of buildings and a rough estimate of the number of dwelling in each building.  Thus, for each sample PSU or locality as a whole, there are two size measures available; the estimated number of households, and the roughly estimated number of dwelling units.  Although these sets of measures proved to be positively correlated, they departed significantly in most cases.  However, for the cells, the number of dwelling units were the only measure of size available.  Therefore, when selecting the sample cells from each sample PSU with probability proportionate to size, the size in terms of dwelling units had to be applied, i.e.  a conceptually different size measure than the one applied at the first stage of selection (households).\n\nFor each sample cell the population has been listed by enumeration of buildings (map reference), and dwelling units.  It should be noted that the number of dwelling units in each building was assessed by listers from outside no thorough inquiries were made as to whether they were inhabited or not.  It was thus expected that errors would occur rather frequently - a problem which is to be evaluated separately on the basis of data collected during the survey.  The listing of dwelling units constitutes the Sampling Frame from which the household sample was selected at a third stage by systematic sampling.  \n\nThe planned sample size was 15,000 households.  However, due to the sampling frame imperfections which were envisaged (several non-eligible units included), oversampling was carried out at a rate of approximately 30%, i.e.  the gross sample selected at the outset comprised around 20,000 dwelling units.  \n\nThe sampling design and sample allocation yield a household sample with varying inclusion probabilities.  In order to have unbiased results, it is thus recommended that all estimates are based on weighed observations, the weights being the inverse of the respective inclusion probabilities.  \n\nAll households in a cell have the same probability of being selected, however varying from cell to cell.  It should be noted that non-eligible dwelling units (i.e.  units which are not inhabited by households) have been removed from the sample.  This does not affect the inclusion probabilities or the weights .  The actual values of the weights are in the range 0.3 to 3.0.  However, 80 % of the weights are in the range 0.7 to 1.4.  Only a very few (small) cells are near the extremes.\n\nSince the sampling design is a complex multi-stage one, variance must be calculated with other methods than those applicable to simple random sampling.  In order to carry out the calculations, the software CENVAR (US Bureau of the Census 1993) has been used.","coll_mode":["Face-to-face [f2f]"],"research_instrument":"e Demographic Survey questionnaire consists of seven main parts Control Sheet which includes items related to quality control  sample identification  interview schedule and interview results Household Roster which includes questions related to the demographic and socio-economic characteristics of persons  Household Mortality Schedule which includes questions related to deaths in the household during the past 24 months.

Centralized staged training  by the same trainers was held in Ramallah for the West Bank and Gaza City for the Gaza Strip trainees \nTraining combined both theoretical and practical components

of weights because of the varying inclusion probabilities that the sample design entails   The weights for a given household  is simply the inverse of its inclusion probability  This yields the so

estimated correctly  but not necessarily the absolute totals the expansions weight have not been used   Rather  the so called relative weights have been employed   For each case they have been calculated as the expansion weight divided by the mean of all the expansion weights   The weights used are the same for households household members women and children (births) since the sample design
