Series Information
The Palestinian Central Bureau of Statistics issued the economic surveys for the Palestinian Territory, which presents the findings of the surveys conducted for 2008 as reference year. These surveys cover most of the economic activities operating in the Palestinian Territory since 1994.
Abstract
The central statistical offices in most countries place heavy emphasis on constructing sound databases for all activities within the Internal Trade sector. PCBS’ Internal Trade Statistics Program is part of the Economic Statistics Program, which is part of the larger program for establishing the System of Official Statistics for Palestine. PCBS initiated, in the reference year 1994, the economic surveys series. The series includes, in addition to Internal Trade survey, surveys on industry, Services, construction-contractors, and transport and storage sectors for the purpose of establishing a time series data base of economic activities in line with international recommendations specified in System of National Account (SNA) 93 and in the UN manual for Services Statistics. The sampling frame for the different economic surveys was based on the findings of the 2004 Establishment Census conducted by PCBS. The services survey provide data needed for:
Objectives:
The objective of the survey was to obtain data on:
1. Number of enterprises and persons engaged in Internal Trade by activity and location.
2. Value of output, intermediate consumption and stocks.
3. Value added components.
4. Payments and transfers.
5. Capital formation.
6. Contribution of the surveyed activities to the GDP and other National Accounts variables.
Target Population
PCBS depends on the International and Industrial Classification of all economic activities, version 3, (ISIC - 3) by the United Nation to classify the economic activities. All enterprises and establishments are classified according to the Establishments Census 2007, which works in agreement with (ISIC - 3).
The Internal trade survey covers the following activities:
1. Sale & repair of motor vehicles .
2. Wholesale trade & commission trade .

Concepts and Definitions
This chapter presents the definitions of the concepts used in the preparation of the survey tools on which data collection and processing are based. These concepts and their definitions are based on international recommendations in the fields of economic statistics and national accounts while taking into account the particular aspects of the Palestinian Territory.
Statistical Unit
It is an economic entity that is capable, in its own right, of owning assets, incurring liabilities and engaging in economic activities and in transactions with other entities.
Persons Engaged
Males and females working in the enterprise including owners, self-employed, unpaid family members, or waged workers who receive their compensations in cash or in kind during a specific reference period. However, this term does not include trainees or those on assignments outside the enterprises or in long unpaid leaves.
Output
It is the value of the final products of goods and services produced by a certain establishment which is used by other units for self-consumed or for the purposes of self gross fixed capital formation. Production includes two categories: Final products and the so-called (under operating products). Production can be classified as follows: Market outputs, Outputs of private account. and other non-market outputs.
Intermediate Consumption
It is the value of the goods and services consumed as inputs, used up or transformed during the production process. It is measured during a specific period in time in a way similar to measuring production. Intermediate consumption is estimated by purchase price, which is defined as the producers' price plus transportation and wholesale and retail trade margins. The value of the gross intermediate consumption on the level of the total economy is the same whether calculated by purchase or producers' price. However, on the detailed level, the two evaluations vary.
Value Added
Value added is a central concept of production and refers to the generated value of any unit that carries out any productive activity. Gross value added is defined as the value of gross production less the value of intermediate consumption.
Compensations of Employees
Compensation of employees is the total remuneration, in cash or in kind, including social security contributions, payable by an enterprise to an employee in return for work done by the latter.
Taxes on Product
Those are taxes that are compulsory cash or in kind payments payable by producers to the general government. it consist of taxes on products payable on goods and services at production, sale, or exchange and other taxes payable on production by resident producers as a result of carrying out the production process.
Assets
It is tangible or intangible (computer software, artistic original) that comes as an output of the production process .It is used frequently or continuously in other production process for more than one year period.
Depreciation
It is the value of the assets which can be reproduced and depreciated during the year, depreciation is calculated on the current substitutive value.
Operating surplus
Value added minus (compensation of employees plus net taxes on production minus subsidies and custom fees plus depreciation).
Gross Fixed Capital Formation
It is the value of what producers own less what they spend on new and used capital goods.
Main Economic Activity
Is the main work of the enterprise based on the (ISIC, rev3) and that contribute by the large proportion of the value added, whenever more than one activity exist in the enterprise.

Sampling
Sampling Procedure
Sample and Frame
The sample of the Internal trade Survey is a single-stage stratified random - systematic sample in which the enterprise constitutes the primary sampling unit (PSU). Three levels of strata were used to arrive at an efficient representative sample (i.e. economic activity, size of employment and geographical levels). The sample size amounted to (2,565) enterprises out of the (60,331 ) enterprises that comprise the survey frame.

Data Collection Mode
Face-to-face [f2f]
Supervision
For insuring data quality, a series of measures were taken in to a account that support accuracy of data collection through the following:
·Selection of specialized fieldwork team of economic back ground, the team was trained theoretically and practically on the survey questionnaire.
· The main fieldwork team was selected according to the training course.
· Field work visits by both fieldwork and project management staff for monitoring and following up data collection process and progress of work, An average of two visits for each governorate, a bout 90% of completed questionnaires was reviewed and corrected if needed, comments and notes were directed to the team accordingly.
· Different levels of supervision and monitoring toke place a according to the following division:
o Fieldworkers
o Fieldworkers supervisors
o Fieldwork coordinator. (Each of them has responsibilities in monitoring )
· Project management receive a daily progress report about completeness and response.
· Conducting a refreshment training course during the stage of data collection for emphasizing the main issues of training and answering questions of fieldworkers about issues faced them in the field.
· We made another visit to some institutions which were visited by the researchers to confirm the accuracy of the data that have been given to researchers and that called the interview, these institutions has been selected randomly by withdrawing a random sample of 10% of the original sample of the survey, and then the data were compared with data from series surveys.

Data Processing
Data Editing
For insuring quality and consistency of data a set of measures were taken into account for strengthening accuracy of data as follows:
Preparing data entry program before data collection for checking readiness of the program for data entry.
A set of validation rules were applied on the program for checking consistency of data.
Efficiency of the program was checked through pre-testing in entering few questionnaires, including incorrect information for checking its efficiency, in capturing these information.
Well trained data keyers were selected and trained for the main data entry.
Weekly or biweekly data files were received by project management for checking accuracy and consistency, notes of correction are provided for data entry management for correction.

Data Appraisal
Estimates of Sampling Error
Statistical Errors:
The findings of the survey are affected by statistical errors due to using sampling in conducting the survey for the units of the target population, which increases the chances of having variances from the actual values we expect to obtain from the data had we conducted the survey using comprehensive enumeration.. The variance of the key goods in the survey was computed and dissemination was carried out on the level of West Bank and Gaza Strip for reasons related to sample design and computation of the variance of the different indicators.
Non-Statistical Errors
These types of errors could appear on one or all the survey stages that include data collection and data entry:
Response errors: these types of errors are related to, responders, fieldworkers, and data entry personnel's. And to avoid mistakes and reduce the impact has been a series of actions that would enhance the accuracy of the data through a process of data collection from the field and the data processing.
