Sampling
Sampling Procedure
Sample Size
The estimated sample size is 9,232 households in the West Bank and Gaza Strip.
Sample Design
The sample is three stage stratified cluster (pps) sample:
First Stage: Selection of a stratified sample of 577 EA with (pps) method.
Second Stage: Selection of a systematic random area sample of 16 households from each enumeration area selected in the first stage.
Third Stage: We selected one person in the household of the (18+) age group in a random method using Kish tables, so that the sex of the person chosen by the serial questionnaire number in the sample. If it is an odd number, we select a male household member and if it is an even number, we select a female household member.
Sample Strata
The population was divided into the following strata:
1. Governorate (17 Governorates, where Jerusalem was considered as two statistical areas).
2. Locality type (urban, rural, refugee camp).
The estimated sample size is 9,232 households in the West Bank and Gaza Strip.

The population was divided into the following strata:
1. Governorate (17 Governorates, where Jerusalem was considered as two statistical areas).
2. Locality type (urban, rural, refugee camp).
Response Rate
The survey sample consists of about 9,232 households of which 7,763 households completed the interview; whereas 5,049 households from the West Bank and 2,714 households in Gaza Strip. Weights were modified to account for non-response rate. The response rate in the West Bank reached 85.4% while it reached 94.2% in Gaza Strip.
Weighting
Sample Weights
Weights Calculation of households and individuals 18+
The weight of statistical units (sampling unit) in the sample is defined as the mathematical inverse of the selection probability, where the sample of the survey is a three-stage stratified cluster (pps) sample. In the first stage, we calculate the weight of enumeration areas which depending on the probability of each enumeration area. then In the second stage, we calculate the weight of households in each enumeration area. Initial household weights resulted from the product of the weight of the first stage and the weight of the second stage. The final household weights were obtained after adjustment of the initial weights with the household estimates for mid-2021 according to design strata (governorate, locality type).
Weights for ROSTER ( all individuals ) were file computed by following :
1- adding the household weights (wh) for each person household which known as the primary weight of person.
2- adjust the primary persons weights to be combatable with the total population at the middle 2021 on the levels: (region (West Bank ,Gaza Strip), sex (male, female), five-year age group (17 group).
3- finally we obtain the final person weight in each adjusted level, and getting the relative weight by dividing each person weight by the average of weights.
Weights for (18+ year) file computed by following:
1- adding the household weights (wh) for each person.
2- We calculate the primary person weight by multiplying (the household weight which the person belong to) and the # of person in the age group (18+ year ) by gender in the household which the person belong to.
3- adjust the primary persons weights to be combatable with the population persons size at the middle of 2021 by these adjusted levels: (region (West Bank ,Gaza Strip), gender (male, female), 14 age group (18-19, 20-24, ..,80+)).
4- finally we obtain the final person weight in each adjusted level which the person belong to.

Data Collection Mode
Computer Assisted Personal Interview [capi]
Supervision
The data of the Smoking and Tobacco Consumption Survey, 2021 were collected through personal interviews using PC-tablets in both the West Bank and Gaza Strip, except for Jerusalem Governorate (J1), where the traditional paper questionnaire method was used due to its specificity, and the application was designed according to a supported survey questionnaire with automated edit rules to check the logicality and consistency of the data, as well as supported by alert or warning messages in the event of illogical and inconsistency in the data. As for the Jerusalem Governorate questionnaire (J1), its data were entered on computers in the entry hall at the headquarters, and the same designed application for tablets was used.

Data Processing
Data Editing
1. Concurrently with the data collection process, a weekly check of the data entered was carried out centrally and returned to the field for modification during the data collection phase and follow up. The work was carried out thorough examination of the questions and variables to ensure that all required items are included, and the check of shifts, stops and range was done too.
2. Data processing was conducted after the fieldwork stage, where it was limited to conducting the final inspection and cleaning of the survey databases. Data cleaning and editing stage focused on:
· Editing skips and values allowed.
· Checking the consistency between different the questions of questionnaire based on logical relationships.
· Checking on the basis of relations between certain questions so that a list of non-identical cases was extracted, and reviewed toward identifying the source of the error case by case, where such errors were immediately modified and corrected based on the source of the error with the documentation process for the checks occurred on the questionnaire.
3. The SPSS program was used to extract and modify errors and discrepancies, to prepare clean and accurate data ready for scheduling and publishing.

Data Appraisal
Estimates of Sampling Error
The data accuracy test includes multiple aspects of the survey, the most notably is sampling errors and non-sampling errors which refers to the staff and survey tools, as well as survey response rates and their most important impact on estimates. This section includes the following:
* Sampling Errors
Data of this survey are affected by sampling errors due to the use of a sample and not a complete enumeration for the target population. Therefore, certain differences are expected to appear in comparison with the real values obtained through censuses. Variance was calculated for the most important indicators. There is no problem at the level of dissemination of the mentioned estmiates at the national level and the level of governorates for both the West Bank and Gaza Strip.
* Non-Sampling Errors
Non-sampling errors are probable in all stages of the project, during data collection or processing. This is referred to as non-response errors, response errors, interviewing errors, and data entry errors. To avoid errors and reduce their effects, great efforts were made to train the fieldworkers intensively. They were trained on how to carry out the interview, what to discuss and what to avoid, through practical and theoretical training during the training course.
Also, data entry employees were trained on the entry program that was examined before starting the data entry process. Continuous contacts with the fieldwork team were maintained through regular visits to the field and regular meetings during the different field visits. Problems faced by fieldworkers were discussed to clarify issues and provide relevant instructions.
The implementation of the survey encountered non-response, where the case (household was not present at home) during the fieldwork visit become the high percentage of the non-response cases. The total non-response rate reached 11.7% which is very low once compared to the household surveys conducted by PCBS. The refusal rate reached 4.1% which is relatively low percentage compared to the household surveys conducted by PCBS, and the reason behind that is that the questionnaire was short and the experience of fieldworkers.
