Palestine - Expenditure and Consumption Survey, PECS 1998 (For documentation only)

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

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 10 households.

Sample size:
========
The total sample size collected, after excluding non-response and related losses, is 2851 households.



Detailed information/formulas on the sampling design are available in the user manual.

Deviations from 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.

Weighting

Self-Weighting Design

Detailed weight formulas are available in the user manual attached to external resources.
