Chapter One: Background

1. Census definition:
The census is one of the pillars of the official statistical system; accordingly, all sectors of society and its private and governmental institutions were requested to support the national team which has the responsibility for planning and conducting the census activities.
The definitions used in the PHC 2017 are based on the de-facto concept as the United Nations standard concepts and definitions stated in order to be consistent with the second census 2007 and to ensure comparability.

2. Objectives of the census:
The population census aims mainly to count the population and their distribution according to relatively stable main characteristics to serve the process of socioeconomic development. Usually, preparations for the census requires as long as 3 - 5 years to conduct the pilot and test the tools and plans in addition to assessing human and financial needs and set the time frames. The census also aims to provide statistical data on the population’s distribution and on their socioeconomic and demographic characteristics in a preset relevant period for all members within the boundaries of the state. It additionally produces data on buildings, housings and establishments and their economic activities within the boundaries of the state. The data is later used for purposes of planning and social and economic development.

3. Enumeration technique:
The enumeration technique was based on direct interviewing of respondents in completing the questionnaires designated for collecting statistical data on the individuals, households, buildings, housing units and establishments, through using special applications for each of buildings and establishments listing phase, and enumeration phase which are uploaded on tablets and supported with maps of the enumeration areas. In addition to the use of data editing mechanism consistent with the use of technology in the census to ensure the quality of data entered into the database and ensure they are logic and error free as much as possible All of these categories underwent comprehensive enumeration, i.e. the operations were not based on any sampling. In addition, the instructions given to the fieldwork teams stressed the importance of returning more than once to absent households to ensure completing data from eligible persons. Field work officials used to play active roles in addressing non-response cases by providing the household with the necessary explanations to alleviate their fears or through public and official related ceremonies.

An enumeration survey was implemented to assess the findings of the census, using a random sample of 288 enumeration areas representing all types of localities in both the West Bank and Gaza Strip. An electronic application was used to collect data of the post enumeration survey supported with enumeration areas maps and data editing mechanism.

4. Census coverage:
The 2017 Census covered all members present in Palestine on the morning of 1st December 2017 regardless of their citizenship, nationality or reasons of presence in Palestine. It also covered the Palestinians temporarily outside of State of Palestine for a period of less than a year for purposes of visit, tourism, treatment or any other reason and who have families inside Palestine. It also covered the detainees and prisoners in Israeli jails regardless of the period of their detention. It did not cover the Palestinians with ID cards and families in Palestine who have been absent for a year or more, with the exception of students studying abroad.

This came based on a decision of the Census’s Executive Committee in its first meeting. The decision provided for the following:

1. Define the coverage of the census to cover all the population, housings and establishments in the State of Palestine, with the exception of Israeli settlements.
2. Counting covers the following groups of individuals:
a. All individuals in Palestine at the moment of the time reference regardless of their citizenship, nationality or reasons for being in Palestine and regardless of their place of presence in Palestine.
b. All Palestinians temporarily abroad of a period of less than a year but with usual place of residence in Palestine. They were counted with other members of their households.
c. All Palestinians who study abroad regardless of the period of their study or residency abroad and all members detained in Israeli jails regardless of the period of their detention. They were counted with other individuals of their households.

5. Sample description:

Sample frame:
It consists of all the enumerated households in the Census 2017 and who are staying in the Palestine at the time of enumeration.

Sample design:
A random sample was selected from each enumeration area enumerated in the census, where the sampling rate reached 20% of the total number of individuals.

Weights estimation:
The weights of the sample were calculated based on the sampling method and added to the data file. These weights should be used when calculating the estimates through the data file.

Estimation using weights:
Calculation of weights are used when working on estimating Mean, Ratio, Proportion, Totals. When we want to estimate the Mean, Ratio, Proportion and Total, we can do that when using the software package such as SPSS by activating the weight variable, or we can multiply all the variables by the weight variable. Noting that the output estimates do not include the under coverage which was calculated through the post-enumeration survey, they include only what was actually counted.

6. Reference date:
The reference date refers to the moment in which the Census data are based. Normally, it refers to the midnight of the day preceding the reference period. Thus, the findings of the Census relate to that night. The midnight of 30/11-1/12 of the year 2017 was adopted as the reference date of the Census.

However, this does not mean that all data relate to the reference date of the Census, taking into account that the reference period for some characteristics refers to periods prior to the reference date of the Census operations. This applies to economic characteristics, births and deaths data.

7. Enumeration period:
It is a specific period in which data are collected on the population and depends on a number of logistical matters. It is recommended that this period be short and not more than two weeks where the relative stability of the population movement is maintained. This period during the 2017 census extended from the morning of 1/12/2017 until the evening 24/12/2017.

8. Census stages:
The Population Housing and Establishment Census-1997 was undertaken in three stages:

The preparatory phase:
This phase extended from January 2016 to March 2017, during which the official census decisions were issued, the organizational structures and the census committees were formed, and all stakeholders and data users were consulted to determine priorities and reach a state of national consent on the census content. The questionnaires and manuals were also designed during this stage, tablets applications were also customized based on the questionnaires and the automated data editing mechanisms. Also, the preparation of checking and coding plans along with the supporting plans, and the estimation of the number of employees. The pre-enumeration test and census pilot were also carried out during this phase.

The field work phase:
This phase extended from mid October 2017 until the end of January 2018. During this period, a comprehensive maps update of all the Palestinian localities was implemented through a separate project that lasted from mid October 2016 till the end of February 2017, in June 2017 All enumeration areas were delineated and demarcated, followed by the listing and numbering of buildings, housing units and establishments in September 2017, and then the main process, the actual population count in December 2017. At the end of this phase, the post enumeration survey was carried out in January 2018.

Data processing phase:
This phase was synchronized with the process of data collection from the field in the listing process until the completion of the post enumeration survey. At this phase, a full examination of all the questions, variables and data entered to the application along with its consistency was carried out. The data was also cleaned and the required fields of the household and housing conditions and establishments questionnaires were coded.

Dissemination phase:
This phase extended from March 2019 until the end of 2019, during which 59 statistical reports related to population, housing, buildings and establishments were published and 10 analytical studies were conducted.

9. Data quality and control mechanism:
The main objective of the quality control programme is to prevent or reduce the incidence of errors to the greatest extent possible and to detect errors in order to take appropriate measures to correct them. Without using such a programme, census data might contain many errors and may not be suitable for use.

For best efficiency, a strict procedure were set up to control data quality in all census stages, including the preparation stage, data processing, and dissemination in order to achieve the required efficiency and accuracy. The control over data quality in the planning stage is highly significant since next stages would be based on it. Therefore, each stage had the sufficient time and measures that guaranteed high census data quality.

9.1 Control mechanism in the preparatory phase
Standard international recommendation for census implementation were reviewed together with the UN Manual on the Implementation of Population and Housing Census, Third Edition, in addition to Review of regional and international experiences in IT-supported censuses for the purpose of developing tools and methodologies to implement an advanced census. Also, several meetings and workshops were held with data users from government agencies and national and international organizations to meet their needs as best as possible. Where expert missions’ reports - especially the report on work methodologies and implementation of international recommendations relevant to the questionnaires and post-enumeration survey showed that PCBS implemented the census in accordance with international recommendations and standards and that measures applied throughout the stages of the census reflected the quality of data.

A number of technical missions were invited to upgrade the capacities of census teams and develop their technical skills as well as to verify the follow-up of all international procedures recommended internationally. Furthermore, different manuals were prepared and ratified to implement the different stages of the census, including Palestinian Localities Guidance, 2017, which was prepared and adopted by a national committee established for this purpose, and automated data editing mechanism was developed consistent with the use of technology in the census and uploading the tools for use to clean the data entered into the database and ensure they are logic and error free as much as possible. The tool also accelerated conclusion of preliminary results prior to finalization of results.

Tablet applications were designed based on the questionnaires that were designed to handle the applications easily and facilitate field data collection. The census pilot was carried out a year before the census. All the questionnaires and uploaded applications on tablets, automated data editing mechanism loaded on applications, coding manuals, scheduling processes and pre-deployment were prepared in this phase. The estimates were calculated from the human resources material needs and the timesheet for accomplishing the tasks and activities required. Prior to this phase, the conditions and mechanism of work with the use of tablets in implementing the census, the evaluation of the efficiency of the training programs and the trainers and the means used in the training, the testing of the work of the field staff and the effectiveness of the use of the Tablets in the implementation of the census from the beginning of work in from delineation of enumeration areas until the completion of the post enumeration survey, and come up with final recommendations regarding the implementation of the General Census of Population, Housing and Establishments 2017.

9.2 Control mechanism in the fieldwork phase
A central operation room was established to manage and monitor the fieldwork covering all geographic areas to monitor performance and quality of data and to abide by the timeframe. The room was chaired by the National Director of the Census with membership of 11 senior officials and the executive director of the census. The purpose of the room was to follow up on work instantly and to make timely policy decisions to facilitate the execution of the census in all stages, and an organizational structure was set for every governorate identifying the different administrative levels starting with the Governorate’s Census Director and his/her assistants then the supervisors then crew leaders and enumerators. Training was organized for every administrative level on administrative and technical tasks and on the mandate of every level.

Training plans and programs for all the teams for all stages were prepared beforehand. Training started with the directors of the census at governorate level and their assistants; supervisors came next and they trained the crew leaders and enumerators. Attention was given to training an additional 30% - 50% team members to provide for cases of resignation, dismissal of staff and for emergencies in case of weak progress, the training included both a theoretical and a practical part. In addition to field visits program that was prepared for on-site follow-up of fieldwork and assess the key problems to solve them. The visits also reviewed how data was entered on the e-applications and teams’ compliance with the instructions they received during the training to ensure good progress.

Moreover, tablets and e-applications system aimed to ensure easy access of field teams in the areas designated to them on the tablets and monitor their work instantly, such as, field teams were prevented from collecting data outside the boundaries of the enumeration areas designated to them to avoid any overlapping. Geographic locations of field teams were audited before entering into the buildings and establishments by saving the geographic coordinates of every building using GPS and comparing them to the geographic location registered for the building, as noted during the maps updating stage. Crew leaders were prevented from completing their work if they exceeded the specified distance. Also, the representation of buildings data on the e-map using specific symbology and different colors to enable field teams identify the status of the building (unvisited, incomplete, complete, removed, non-census buildings). And Field teams were provided with the possibility of adding and removing buildings on the e-maps based on their observation on the ground.

Supervisors also repeated the interview to collect data on buildings, housing units and establishments at random, covering 3% of the units accomplished by the crew leaders in each enumeration area during the listing phase. The crew leader gathered data for 2% of the households visited by enumerators to ensure that the household was included and that its members’ data is harmonized. Enumerators received feedback on the errors they made. The re-interview process aimed to examine the coverage of the work of the crew leaders and enumerators and to examine the accuracy of the data collected by them.
A post enumeration survey was conducted to cover 4% of the enumeration areas to assess the rate of coverage of individuals and households. Full count was repeated for all households and individuals in the selected enumeration areas. The survey showed that the under coverage rate was 1.7%.

9.3 Control mechanism in the data processing phase
The maps uploaded on the applications helped in preventing collection of data outside the boundaries of the enumeration areas designated to every fieldwork team to ensure avoiding any overlapping as GPS and GIS were used to avoid duplication and omission of counting units (buildings, housings, establishments, and households,).

Automated databases were edited directly during data collection in all stages to minimize errors since the system sends warning messages and error messages to fieldworkers requesting either amendment or verification of data. Data from official documents were used as much as possible.

Special screens for coding were also prepared beforehand and codification manuals were uploaded thereon and tested by specialized staff at PCBS. The team who run the coding was selected and trained to comprise experienced and qualified workers. Codification of economic activities, occupations, countries, citizenships, educational specializations and localities was done centrally.

10. History of censuses in Palestine:

1. The first population census in Palestine was executed in October 1922 during the British mandate era. The estimated population was 752 thousand.

2. A second population census was executed in November 1931. The population was estimated at 1.033 million.

3. A demographic survey was executed in 1944. The estimated number of the population of Palestine was estimated at 1.74 million.

4. Under the Hashemite Kingdom of Jordan administration of the West Bank, the Palestinian population in the West Bank was estimated at 667 thousand in the 1952 census and 805 thousand in the 1962 census.

5. Under the Israeli occupation, a comprehensive enumeration of the Palestinian population was done in September 1967. About 599 thousand inhabitants were enumerated in the West Bank and approximately 400 thousand in the Gaza Strip. It is worth mentioning that about 400 thousand Palestinians were displaced from the Palestinian territory immediately after the Israeli occupation in 1967.

6. PCBS conducted the first Palestinian census in 1997. The estimated population in the West Bank (West Bank excluding J1, i.e., the part of Jerusalem which was annexed by Israel in 1967) and Gaza Strip was 2.6 million. The estimated population of J1 at the time was about 210 thousand. The Israeli occupation prevented the national census team from surveying the J1 population.

7. The Palestinian Central Bureau of Statistics conducted the third population, housing and establishment in 2017, and it's the first census to be implemented by using new technologies and (GIS).
