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>\n\nThe 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. \nFurthermore, this survey is a fundamental cornerstone in the process of studying the nutritional status in the Palestinian territory.\n\nThe 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.","coll_dates":[{"start":"2009-01-15","end":"2010-01-14","cycle":"Annual"}],"nation":[{"name":"Palestine","abbreviation":"PAL"}],"geog_coverage":"The survey data covers urban, rural and camp areas in West Bank and Gaza Strip.","analysis_unit":"1- Household\/family.\n2- Individual\/person.","universe":"The survey covered all the Palestinian households who are a usual residence in the Palestinian Territory.","data_kind":"Sample survey data [ssd]","notes":"Household: Includes geographic, social, and economic characteristics of households, namely, household composition, dwelling characteristics, ownership of assets indicators, heads' and spouses' characteristics, annual household expenditure and income.\n\nIndividual: Includes demographic, migration, education, labor and health characteristics, as well as annual income for household members identified as earners.

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>\n\nSample and Frame:\n============\n The sampling frame consists of all enumeration areas which were enumerated in 2007, each numeration area consists of buildings and housing units with average of about 120 households in it. These enumeration areas are used as primary sampling units PSUs in the first stage of the sampling selection. \n \nSample Design:\n=========\nThe sample is a stratified cluster systematic random sample with two stages:\nFirst stage: selection of a systematic random sample of 191 enumeration areas.\nSecond stage: selection of a systematic random sample of 24 households from each enumeration area selected in the first stage.\n\nNote: in Jerusalem Governorate (J1), 13 enumeration areas were selected; then in the second phase, a group of households from each enumeration area were chosen using census-2007 method of delineation and enumeration. This method was adopted to ensure household response is to the maximum to comply with the percentage of non-response as set in the sample design.\n\nEnumeration areas were distributed to twelve months and the sample for each quarter covers sample strata (Governorate, locality type)\n\n\nSample strata:\n==========\nThe population was divided by:\n1- Governorate\n2- Type of Locality (urban, rural, refugee camps)\n\nSample Size:\n========\nThe calculated sample size for the Expenditure and Consumption Survey in 2009 is about 3,848 households, 2,654 households in West Bank and 1,194 households in Gaza Strip.","coll_mode":"Face-to-face [f2f]","research_instrument":"The PECS questionnaire consists of two main sections: \n\nFirst section: \nCertain 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:\n\nCover 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.\n\nStatement of the family members: Contains social, economic and demographic particulars of the selected family.\n\nStatement of the long-lasting commodities and income generation activities:\nIncludes a number of basic and indispensable items (i.e., Livestock, or agricultural lands).\n\nHousing 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.\n\nMonthly and Annual Income: Data pertaining to the income of the family is collected from different sources at the end of the registration \/ recording period.\n\n Assistance and poverty: includes questions about household conditions and assistances that got through the the past month.\n\nSecond section: \nThe 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.\nThese data was abotained from the recording book which is covered a period of month for each household.","coll_situation":"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 10-20 female interviewers.\n\nAll 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.","weight":"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.\nFirst stage weight:\nThe 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 the same stratum h.\n\nSecond stage weight:\nThe 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. \n\nThe primary weights of households before modification is the multiplication of the weights of the first and second stages.\nThose 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 2009 by adjustment levels were used.\nThe final weight for the household (FHW) is then a multiplication of the adjustment factor by the primary weight for the household.","cleaning_operations":"Raw Data\n=======\nData editing took place through a number of stages, including:\n1. Office editing and coding\n2. During data entry\n3. Structure checking and completeness\n4. Structural checking of SPSS data files\n\n\nHarmonized Data\n============\n- The Statistical Package for Social Science (SPSS) is used to clean and harmonize the datasets.\n- The harmonization process starts with cleaning all raw data files received from the Statistical Agency.\n- Cleaned data files are then all merged to produce one data file on the individual level containing all variables subject to harmonization.\n- A country-specific program is generated for each dataset to generate\/ compute\/ recode\/ rename\/ format\/ label harmonized variables.\n- A post-harmonization cleaning process is then conducted on the data.\n- Harmonized data is saved on the household as well as the individual level, in SPSS and converted to STATA format.","method_notes":"Raw Data\n==========\nBoth data entry and tabulation were performed using the ACCESS and SPSS software programs. Data entry was organized in 8 files, corresponding to the main parts of the questionnaire. A data entry template was designed to reflect an exact image of the questionnaire, and included various electronic checks: logical check, range checks, consisting checks and cross-validation. Complete manual inspection of results after data entry was performed, and questionnaires containing field-related errors were sent back to the field for corrections."},"analysis_info":{"response_rate":"The survey sample consists of about 4,699 households of which 3,627 households completed the interview; whereas 2,654 households from the West Bank and 973 households in Gaza Strip. Weights were modified to account for non-response rate. The response rate in the West Bank reached 85.5% while in the Gaza Strip it reached 67%. The response rate in the Palestinian Territory reached 79.57%.","sampling_error_estimates":"The impact of errors on the data quality was reduced to the minimal due to the high efficiency and outstanding selection, training, and performance of the fieldworkers.\nProcedures adopted during the fieldwork of the survey were considered a necessity to ensure the collection of accurate data, notably:\n1) Develop schedules to conduct field visits to households during survey fieldwork. The objectives of the visits and the data that is collected on each visit were predetermined.\n2) Fieldwork editing rules were applied during the data collection to ensure corrections were implemented before the end of fieldwork activities.\n3) Fieldworker were instructed to provide details in case of extreme expenditure or consumption of the household.\n4) Postpone the questions on income to the last visit at the end of the month .\n5) Validation rules were embedded in the data processing systems along with procedures to verify data entry and data editing."}},"data_access":{"dataset_use":{"conf_dec":[{"txt":"To access the micro data, researchers are required to register on the ERF website and comply with the data access agreement. \n\nThe data will be used only for scholarly research, or educational purposes.
