Series Information
The Palestinian Central Bureau of Statistics (PCBS) conducted a Household Expenditure and Consumption Survey for the first time between 1/10/1995 and 30/9/1996 and then conducted the second survey between 1/1/1997 and 31/1/1997.
The findings of these surveys aim at constituting a solid database and enabling PCBS to publish detailed statistics regarding expenditure and consumption for the first time.

Abstract
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
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
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
Sample and Frame:
============
The target population in the survey sample comprises all households living in the West Bank and Gaza Strip, excluding nomads and students.
The sample design is a stratified two-stage design for households selected to be interviewed.
At the first stage a sample of cells (PSUs) was selected from PCBS master sample frame.
At the second stage, a sample of households was selected after a complete household listing of the sampled cells.
Sample design:
=========
Four levels of stratification have been made:
1. Stratification by District.
2. Stratification by place of residence, which comprises:
(a) Municipalities (b) Villages (C) refugees camps
3. Stratification by locality size
4. Stratification by cell identification in that order
Sample size:
========
The sample size is about 3591 households allowing for non-response and related losses.
Target cluster size:
============
The target cluster size or the "sample-take" is the average number of households to be selected per PSU. In this survey, the sample take is around 10 households.
Detailed information/formulas on the sampling design are available in the user manual.
Deviations from the Sample Design
The standard errors for the main survey estimates were calculated to give the user an idea of their reliability or precision. Whereas, the variance was calculated using the method of ultimate clusters within any domain of estimation.
Detailed information on the sampling design deviation and calculation of the variance is available in the user manual.
Detailed information on the sampling design deviation and calculation of the variance is available in the user manual.
Response Rate
(3591) households were selected, representing the West Bank and Gaza Strip, (2502) households in the West Bank and (1089) households in Gaza Strip.
Excluding the uninhabited housing units, the sample of the survey become (3477) households, (2423) households in the West Bank, and (1054) households in Gaza Strip.
A total of (3270) households completed the questionnaire: (2279) household in the West Bank and (991) households in Gaza Strip.
The non response rate is, accordingly, 6.3% for all Palestinian territory.

Data Collection Notes
1) Pilot Survey
The questionnaire, fieldwork procedures and instructions, data entry template and instructions, and the estimated costs for PECS1, carried out by PCBS in the West Bank and Gaza Strip during the period "October 1995-September 1996", was considered the pilot survey for the 1997 survey (PECS 2).
PECS 95/96 survey results were thoroughly evaluated, and modification in the plan, questionnaire, fieldwork procedures... etc were made accordingly to be implemented in the 1997 survey.
2) Field Operations
Six teams of female interviewers, four in the West Bank and two in Gaza Strip carried out data collection. Each team consisted of a supervisor, a field editor, and 4-5 interviewers.
Fieldwork teams were distributed to different districts according to sample allocation.
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 PECS1. 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 the fieldwork.
The interviewer undertook between 120 and 150 household visits in a month. The households were asked to keep daily records in a dairy during their recording month.

Questionnaires
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.

Second section: The second section of the questionnaire includes a list of 54 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 707 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.

Raw Data
=======
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 Error
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 3.4%).
