Informal Sector Survey [hh/iss]
Series Information
This survey implemented for seventh volume of the Transport Survey: Informal Sector for the Palestinian Territory. This report presents findings of the survey for the year 2002 for the Palestinian Territory.
The survey results include data related to the number of operating vehicles, persons engaged, compensation of employees, output, intermediate consumption, value added, capital formation and other indicators. Data was tabulated by activity and region.
Covering informal economic activity with a statistical survey is not an easy task. One challenge was the preparation of a convenient sampling frame. Such challenges should be taken into account when studying results of the survey.

Abstract
There is increasing concern in national statistical offices about coverage of informal economic activities. PCBS has given priority to transport activities, due to their importance to the Palestinian economy. The informal transport survey complements the 2002 formal transport sector survey. The PCBS began by exerting tremendous effort to establish a sampling frame. All land transport stops in major Palestinian cities were defined and data about the number and characteristics of operating vehicles were collected in order to stratify the population into homogenous stratum.
The survey covers activities of the informal sector according to (ISIC-3) for both:
Non-scheduled passenger land transport (6022)
Freight transport by road (6023)
Objectives:
Objectives of this survey are the following:
1. Number of transport vehicles and persons engaged by activity.
2. Value of output and intermediate consumption.
3. Value added components.
4. Fixed assets and other selected variables.

Sampling
Sampling Procedure
Sample design:
The design used is a random cluster stratified sample:
quota sample proportional to the size of the station. The sample size amounted to (1643) vehicles of the total (13157) vehicles that comprise the survey frame.
Sample Clusters:
Barking divided to clusters on the following levels:
1. Transport kind: vehicles divided according to its activity to:
· taxi passengers.
· Privet passengers.
· Freight transport by road.
2. Vehicles model: vehicles divided according to its model to:
· Model 1990 below.
· Model 1991 up

· Model 1991 up
Response Rate
The Response ratio is 90.0%
Weighting
The sampling weight of the vehicle is the mathematical turned of the possibility selection of that enterprise. It is necessary to use weights in the estimation of the survey society because of the differentiation in the possibility of vehicles' selection from another one.

Supervision
This section presents technical notes concerning the statistical quality of the collected data, which should be taken into consideration as follows:
· Many constraints were encountered during the implementation of this survey due to the Israeli measures, which restrict movement between cities and localities in the Palestinian Territory.
· Simple changes in values of same variables in the tables are noticeable due to the data processing.
· Intermediate consumption excluded insurance premiums in the table of service expenditures.

Data Collection Notes
Data Collecting
a Examine the questionnaire formally and technically.
b Examine the forms used in fieldwork.
c. Examine titles and definition information's.
d. Study the explicit and implicit refusal cases.
e. Study the time needed to reach the establishment.
This test realized sought aims, where some notes taken about the questionnaire, data, titles and responding rates. Then the fieldwork documents took some changes depended on these notes.
Selection and Training of Field workers
Field workers are subjected to personal interviews and undergo certain practical and theoretical training to provide them with the key components and the definitions of the questionnaire. The best trainees who pass the theoretical and practical training chosen to collect data.
Fieldwork Management and Organization
Fieldwork directorate supervises data collection and coordinate to the fieldworkers to perform the set plans for each survey. The fieldwork staff constitute of coordinators, supervisors in addition to the editing staff. Implementing this mission requires the existence of district offices close to working areas to be used as centers for fieldwork staff and fieldwork tools.
Data Collection Method
Fieldworkers collect data through personal interviews with the owners or the managers of the selected economic establishments.
Fieldwork editing
Fieldworkers and supervisors make an initial formally and technically editing depends on prepared editing rules.
Office Editing
The filled questionnaires are subjected to editing where the inaccurate questionnaires resend to the fieldwork again to correct the mistakes and to complete the missing parts.
Coding
After finish editing process the completed questionnaires subject to coding process to be prepared to the data entry process.

Data Processing
Data Editing
Data Processing
Office Editing:
The office editor also edits the questionnaire in order to be ready to be sent to coding and data entry.
Coding:
After the editor finishes editing the questionnaire, a coding are used according to (ISIC - 3), then the questionnaire is transferred to data entry.
Data Entry Training:
The data entry training begins before the data entry process, the training is of two parts theoretically and practically.
Data Entry Administrative:
The Information System Directorate administrates the whole process with all its requirements. The data entry team is of data entry employees and a supervisor.
Editing of Data Entry:
There are tow steps:
First: throughout the data entry itself since the program itself is available to correct mistakes in data entry.
Second: Listing of questionnaires which are still have mistakes in data entry.
Data Tabulation:
A primary tables are exerted after the process of data entry and editing. A process of editing data is being taken to have at the end a final correct data tables.

Data Appraisal
Estimates of Sampling Error
Difference in Estimations
It is necessary to associate with an estimated statistical number by a sampling survey another one which refers to the existing accuracy in the estimation. CENVAR program is used for estimation. The following measures are used for the main economic indicators:
1. Standard Error.
2. Coefficient of Variation.
3. DEFF.
4. 95% Confidence Interval.
