Sampling
The sample of the economic surveys series 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 draw up an efficient representative sample (i.e., economic activity, size of workforce and geographical location). This methodology was used to draw a sample of middle enterprises and whole frame for large enterprises based on the framework of large and middle enterprises alone, for small enterprises data were estimated based on a time series of the results of economic surveys.
·The response rate for the Construction Contractors Survey 2011 is of 82.5%
The sampling weight of the enterprise 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 enterprises' selection from one another. The weights are adjusted to compensate for nonresponse enterprises.
Survey instrument
All of the economic surveys series used the same questionnaire, with a few different characteristics for each survey. The design of the 2011 questionnaire takes into account the major economic variables pertaining to the sector examined and the needs to be met to compile the National Accounts for Palestine.

Fieldwork ·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: oFieldworkers oFieldworkers supervisors oFieldwork 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.
Workers Selection and Training: The interviewers in the fieldwork are selected from the experienced ones in the statistical work and they are also trained theoretically and practically. Fieldwork operations: They are initiated after the recruitment and training of qualified interviewers. The PCBS's Fieldwork Directorate administers fieldwork activities including interviewing activities. Data Collecting Method: Data are gathered by using an interview with the enterprise owner or general manager by applying the survey questionnaire.
Data processing
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
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 Palestinian Territory 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.
