    - A fifth survey (PECS 2004) between 15/1/2004 and 14/1/2005.
    - And a sixth survey (PECS 2005) between 15/1/2005 and 14/1/2006.
    Abstract
    <p style="border:solid thin black;"> THE CLEANED AND HARMONIZED VERSION OF THE SURVEY DATA PRODUCED AND PUBLISHED BY THE ECONOMIC RESEARCH FORUM REPRESENTS 100% OF THE ORIGINAL SURVEY DATA COLLECTED BY THE PALESTINIAN CENTRAL BUREAU OF STATISTICS </p>

    The basic goal of the Household and Consumption Survey is to provide a necessary database for formulating national policies at various levels. This survey provides the contribution of the household sector to the Gross National Product (GNP). It determines the incidence of poverty, and provides weighted data which reflects the relative importance of the consumption items to be employed in determining the benchmark for rates and prices of items and services.
    Furthermore, this survey is a fundamental cornerstone in the process of studying the nutritional status in the Palestinian territory.

    The raw survey data provided by the Statistical Agency were cleaned and harmonized by the Economic Research Forum, in the context of a major project that started in 2009. During which extensive efforts have been exerted to acquire, clean, harmonize, preserve and disseminate micro data of existing household surveys in several Arab countries.

    Sampling

    Sampling procedure

    Sample and Frame:
    =============
    The sampling frame consists of all enumeration areas which enumerated in 1997 and the numeration area consists of buildings and housing units and has in average about 150 households in it. We use the enumeration areas as primary sampling units PSUs in the first stage of the sampling selection. The enumeration areas of the master sample were updated in 2003.

    Sample Design:
    =========
    The sample is stratified cluster systematic random sample with two stages:
    The calculated sample size is 2,778 households, the completed households were 2,152 (1,427 in the west bank and 725 in the Gaza strip).
    First stage: selection a systematic random sample of 120 enumeration areas.
    Second stage: selection a systematic random sample of 12-18 households from each enumeration area selected in the first stage.

    Sample strata:
    =========
    We divided the population by:
    1- Region (North West Bank, Middle West Bank, South West Bank, Gaza Strip)
    2- Type of Locality (urban, rural, refugee camps)

    Target cluster size:
    ============
    The target cluster size or "sample-take" is the average number of households to be selected per PSU. In this survey, the sample take is around 12 households.

    Sample Size:
    ========
    The calculated sample size is 2,778 households, the completed households were 2,152 (1,427 in the west bank and 725 in the Gaza strip).
    Response rates
    The survey sample consists of about 2,778 households interviewed over a twelve months period between (January 2005-January 2006), 2,152 households completed interview, of which 1,427 in the West Bank and 725 household in Gaza Strip, the response rate was 77.5% in the Palestinian Territory.
    Weighting
    The weight of statistical unit (sampling unit) in the sample is defined as the mathematical inverse of the selection probability. The sample of the survey is two stage stratified cluster sample, thus, the weights are calculated for each stage and the Households Weights is the multiplication of the two weights.

    First stage weight:
    The sample of enumeration areas is selected and the weight is called enumeration area weight (the sampling unit is enumeration area).The weight for enumeration areas from stratum h is calculated by dividing the number of enumeration areas in stratum h on the sample size of enumeration areas in stratum h.

    Second stage weight:
    The sample of households is selected and the weight is called household weight (the sampling unit is household). The weight of the Household from enumeration area (cluster) k is calculated by dividing the number of households in each cluster with the sample size of households within the cluster k.

    The primary weights of households before modification is the multiplication of the weights of the first and second stages.
    Those primary weights were then adjusted to compensate for the non-response through calculating an adjustment factor for households weights by adjustment levels (Governorate and locality type).The households projections in 2005 by adjustment levels were used.
    The final weight for the household (FHW) is therefore a multiplication of the adjustment factor by the primary weight for the household.

    Survey instrument

    Questionnaires
    The PECS questionnaire consists of two main sections:

    First section:
    Certain articles / provisions of the form filled at the beginning of the month, and the remainder filled out at the end of the month. The questionnaire includes the following provisions:

    Cover sheet: It contains detailed and particulars of the family, date of visit, particular of the field/office work team, number/sex of the family members.

    Statement of the family members: Contains social, economic and demographic particulars of the selected family.

    Statement of the long-lasting commodities and income generation activities:
    Includes a number of basic and indispensable items (i.e., Livestock, or agricultural lands).

    Housing Characteristics: Includes information and data pertaining to the housing conditions, including type of house, number of rooms, ownership, rent, water, electricity supply, connection to the sewer system, source of cooking and heating fuel, and remoteness/proximity of the house to education and health facilities.

    Monthly and Annual Income: Data pertaining to the income of the family is collected from different sources at the end of the registration / recording period.

    Assistance and poverty: includes questions about household conditions and assistances that got through the the past month.

    Second section:
    The second section of the questionnaire includes a list of 55 consumption and expenditure groups itemized and serially numbered according to its importance to the family. Each of these groups contains important commodities. The number of commodities items in each for all groups stood at 667 commodities and services items. Groups 1-21 include food, drink, and cigarettes. Group 22 includes homemade commodities. Groups 23-45 include all items except for food, drink and cigarettes. Groups 50-55 include all of the long-lasting commodities. Data on each of these groups was collected over different intervals of time so as to reflect expenditure over a period of one full year, except the cars group the data of which was collected for three previous years.
    These data was abotained from the recording book which is covered a period of month for each household.

    Notes on data collection
    Four teams of female interviewers, three in the West Bank and one in the Gaza Strip carried out data collection. Each team consisted of a supervisor, and 3-4 female interviewers.
    All field staff received a training session combining general theoretical and practical components. Interviewers, supervisors and editors for the survey were selected from those who worked on the previous rounds of PECS Surveys. Fieldwork procedures and organization were designed to ensure adequate supervision and the collection of high quality data. To this end, several quality control measures were used throughout fieldwork. An interviewer undertook between 120 and 150 household visits in a month. The households were asked to keep daily records in a diary during their recording month. The interviewer transferred the records in a questionnaire on a weekly basis. Data on durable goods were captured by the recall method for the last 12 months (rounds), in order to avoid large variance in estimates when the one-month approach is used.

    Data processing

    Cleaning operations
    Raw Data
    =======
    Data editing took place though a number of stages, including:
    1. Office editing and coding
    2. Data entry
    3. Structure checking and completeness
    4. Structural checking of SPSS data files

    Harmonized Data
    ============
    - The Statistical Package for Social Science (SPSS) is used to clean and harmonize the datasets.
    - The harmonization process starts with cleaning all raw data files received from the Statistical Agency.
    - Cleaned data files are then all merged to produce one data file on the individual level containing all variables subject to harmonization.
    - A country-specific program is generated for each dataset to generate/ compute/ recode/ rename/ format/ label harmonized variables.
    - A post-harmonization cleaning process is then conducted on the data.
    - Harmonized data is saved on the household as well as the individual level, in SPSS and converted to STATA format.

    Data appraisal

    Estimates of sampling errors
    Generally, surveys samples are exposed to two types of errors.
    The statistical errors, being the first type, result from studying a part of a certain society and not including all its sections. And since the Household Expenditure and Consumption Surveys are conducted using a sample method, statistical errors are then unavoidable. Therefore, a potential sample using a suitable design has been employed whereby each unit of the society has a high chance of selection. Upon calculating the rate of bias in this survey, it appeared that the data is of high quality.
    The second type of errors is the non-statistical errors that relate to the design of the survey, mechanisms of data collection, and management and analysis of data. Members of the work commission were trained on all possible mechanisms to tackle such potential problems, as well as on how to address cases in which there were no responses (representing 10.2%).
