Series information
Expenditure and Consumption Survey, Round 11 is the eleventh round of PECS surveys.
Previously, 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.
PCBS then conducted a series of surveys on the following dates:
- A second survey (PECS 1997) between 1/1/1997 and 31/1/1997.
- A third survey (PECS 1998) between 1/1/1998 and 31/1/1998.
- A fourth survey (PECS 2001) between 15/3/2001 and 14/3/2002.
- A fifth survey (PECS 2004) between 15/1/2004 and 14/1/2005.
- A sixth survey (PECS 2005) between 15/1/2005 and 14/1/2006.
- A seventh survey (PECS 2006) between 15/1/2006 and 14/1/2007.
- An eighth survey (PECS 2007) between 15/1/2007 and 14/1/2008.
- A ninth survey (PECS 2008) between 15/1/2008 and 14/1/2009.
- A tenth survey (PECS 2009) between 15/1/2009 and 14/1/2010.
- And an eleventh survey (PECS 2010) between 15/1/2010 and 14/1/2011.
The findings of these surveys constituted a solid database and enabled PCBS to publish detailed statistics on expenditure and consumption.

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
<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>
Sample and Frame:
============
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.
Sample Design:
==========
The sample is a stratified cluster systematic random sample with two stages:
First stage: selection of a systematic random sample of 192 enumeration areas.
Second stage: selection of a systematic random sample of 24 households from each enumeration area selected in the first stage.
Note: 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.Enumeration areas were distributed to twelve months and the sample for each quarter covers sample strata (Governorate, locality type)
Sample strata:
The population was divided by:
====================
1- Governorate
2- Type of Locality (urban, rural, refugee camps)
Sample Size:
========
The calculated sample size for the Expenditure and Consumption Survey in 2010 is about 3,757 households, 2,574 households in West Bank and 1,183 households in Gaza Strip.

Sample Size:
========
The calculated sample size for the Expenditure and Consumption Survey in 2010 is about 3,757 households, 2,574 households in West Bank and 1,183 households in Gaza Strip.
Response rates
The survey sample consisted of 4,767 households, which includes 4,608 households of the original sample plus 159 households as an additional sample. A total of 3,757 households completed the interview: 2,574 households from the West Bank and 1,183 households in the Gaza Strip. Weights were modified to account for the non-response rate. The response rate in the Palestinian Territory 28.1% (82.4% in the West Bank was and 81.6% in Gaza Strip).
Weighting
The weight of statistical units (sampling unit) in the sample is defined as the mathematical reciprocal of the probability to select the unit. The sample of the survey is stratified cluster
systematic random one with two stages. Thus, a weight is 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 areas weight (the sampling unit is enumeration areas).
The weight for enumeration areas from stratum h by the design of sample is calculated by dividing the # of enumeration areas in stratum h on the sample size of enumeration areas in
stratum h by the following equation (1):
Wih=Mh/Nh
Where
H: The code of enumeration area stratum I by Governorate and locality type
Wih :The weight of enumeration area i in stratum h
Mh : The # of enumeration areas in the stratum h from the population census frame in 2007
nh :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). Household weight is calculated from stratum k by dividing number of households in each
stratum with the sample size of households within the stratum k, using the following formula:
Wik=Mk/Nk
k: Household stratum symbol i by Governorate and locality type
Wik : Weight of household i in the stratum k
Mk : enumeration areas reflecting the percent change in the strata design from 2007 to 2010 using household's estimates for 2010
nk : Household sample size in the stratum k
The primary weight of households before modification is the multiplication of the weights of the first and second stages.
Then the weights for households were adjusted to compensate for the non response of households by calculating the factor of weights adjustment through dividing the sample size of household from stratum h on the # of the respondent in the households from stratum h,
by the following equation (2) :
Fh=Mh/Nh
Fh : The factor of weights adjustments in stratum h
Mh : The sample size of households in stratum h
Nh : The # respondent households in stratum h
The final weight for the households is then a multiplication of the factor of the weights adjustment by the primary weights for the household by the following equation (4):
wF'h=Wh Fh
systematic random one with two stages. Thus, a weight is calculated for each stage and the Households Weights is the multiplication of the two weights.

Second stage weight:
The sample of households is selected and the weight is called household weight (the sampling unit is household). Household weight is calculated from stratum k by dividing number of households in each
stratum with the sample size of households within the stratum k, using the following formula:

Mk : enumeration areas reflecting the percent change in the strata design from 2007 to 2010 using household's estimates for 2010
nk : Household sample size in the stratum k
The primary weight of households before modification is the multiplication of the weights of the first and second stages.
Then the weights for households were adjusted to compensate for the non response of households by calculating the factor of weights adjustment through dividing the sample size of household from stratum h on the # of the respondent in the households from stratum h,
by the following equation (2) :

Survey instrument
Questionnaires
The questionnaire consists of two main parts:
First: Survey's questionnaire
Part of the questionnaire is to be filled in during the visit at the beginning of the month, while the other part is to be filled in at the end of the month. The questionnaire includes:
Control sheet: Includes household’s identification data, date of visit, data on the fieldwork and data processing team, and summary of household’s members by gender.
Household roster: Includes demographic, social, and economic characteristics of household’s members.
Housing characteristics: Includes data like type of housing unit, number of rooms, value of rent, and connection of housing unit to basic services like water, electricity and sewage. In addition, data in this section includes source of energy used for cooking and heating, distance of housing unit from transportation, education, and health centers, and sources of income generation like ownership of farm land or animals.

The list includes 55 groups of expenditure and consumption where each is given a sequence number based on its importance to the household starting with food goods, clothing groups, housing, medical treatment, transportation and communication, and lastly durable goods. Each group consists of important goods. The total number of goods in all groups amounted to 667 items for goods and services. Groups from 1-21 includes goods pertinent to food, drinks and cigarettes. Group 22 includes goods that are home produced and consumed by the household. The groups 23-45 include all items except food, drinks and cigarettes. The groups 50-55 include durable goods. The data is collected based on different reference periods to represent expenditure during the whole year except for cars where data is collected for the last three years.

Data appraisal
Estimates of sampling errors
The impact of errors on data quality was reduced to a minimum due to the high efficiency and outstanding selection, training, and performance of the fieldworkers.
Procedures adopted during the fieldwork of the survey were considered a necessity to ensure the collection of accurate data, notably:
1) Develop schedules to conduct field visits to households during survey fieldwork. The objectives of the visits and the data collected on each visit were predetermined.
2) Fieldwork editing rules were applied during the data collection to ensure corrections were implemented before the end of fieldwork activities.
3) Fieldworkers were instructed to provide details in cases of extreme expenditure or consumption by the household.
4) Questions on income were postponed until the final visit at the end of the month.
5) Validation rules were embedded in the data processing systems, along with procedures to verify data entry and data edit.
