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.

Sampling
Sampling Procedure
Sample and Frame:
The sampling frame consists of all areas enumerated in 2007. Each enumeration area consists of buildings and housing units comprising an average of around 124 households. These enumeration areas are used as primary sampling units (PSUs) in the first stage of the sampling selection.
Sample Size
The estimated sample size for the Expenditure and Consumption Survey is 5,171 households for the whole year. The non-response rate is estimated at around 20% of the total sample.
The calculated sample size for the Expenditure and Consumption survey 2011 is about 4,317 households, 2,834 households in West Bank and 1,483 households in Gaza Strip, with response rate88% (87.5% in west bank, 89.1% in gaza strip)
The sample is a two-stage stratified cluster sample:
First stage: selection of a systematic random sample of 215 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), 14 enumeration areas were selected. In the second stage, a group of households from each enumeration area were chosen using the 2007 census method of delineation and enumeration to obtain 24 responsive households. This ensures household response is the maximum to comply with the percentage of non-response as set in the sample design.
Enumeration areas were distributed over twelve months and the sample for each quarter covers sample strata (governorate, locality type).
Sample Strata:
The population was divided by:
1- Governorate
2- Locality type (urban, rural, refugee camp)

Weighting
Calculation of Households Weights:
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 weight of households before modification is the multiplication of the
weights of the first and second stages.
Then we adjust the primary weights for the households to compensate for the non - response of households by calculating adjustment factor for households weights for adjustment levels (Governorate and locality type ) by using households projections by adjustment levels in 2006.
Then the final weight for the households ( FHW) is a multiplication of the adjustment factor by the primary weights for the household

Data Collection Notes
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.
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.
