The 2009 Crime Victimization Survey in Ghana was carried out in four Metropolitan Assemblies of the country. They are Sekondi-Takoradi, Accra, Kumasi and Tamale Metropolitan Assemblies. It is the first of its kind to be conducted in the country. It is a pilot study designed to facilitate a broader understanding of crime and its burden on the citizenry.

The population in individual households that dwell in living quarters in each of the four Metropolitan Assemblies constituted the sampling frame. The institutional population (such as persons in hospitals, prisons, hotels and similar establishments, persons living on the streets or the homeless) were excluded from the frame.
The sample design was a clustered, multi-stage probability sample. The updated list of enumeration areas (EAs) that were used for the 2000 Population and Housing Census constitute the sampling frame for the four Metropolitan Assemblies for the survey. The EAs are defined as Primary Sampling Units (PSUs), while households within the selected EAs constitute the Secondary Sampling Units (SSUs).
Selection of the sample was in two stages. At the first stage of sampling, 120 EAs (PSUs) were selected with Probability Proportional to Size (PPS). That is determination of the sample size uses proportional allocation based on each Metropolitan Assembly's share of the total population of the four metropolitan areas. The selection of EAs is accomplished by carrying out sampling operations independently within each metropolitan area. At the second stage, 13 households were selected systematically with a random start and interval separately for each EA to produce a total of 1,560 households for the four metropolitan areas.
Deviations from the Sample Design
No deviation of the original sample design was made
No weighting was computed
Dates of Data Collection (YYYY/MM/DD)
Mode of data collection
The data were collected by six teams. Each team was manned by one supervisor. Among others, the supervisor coordinated community entries, coordinate field data collection activities, including management of the field teams, and supplies and equipment. Additionally, the field supervisor assigned the work to the interviewers, reviewed work by interviewers, spot checked work and maintained field control documents. He/she also served as the liaison officer between the fieldstaff and the secretariat at the head office. Senior Officers from the project secretariat and Management of GSS as well as the Data Processing consultant, also embarked on a number of supervisory field visits, aimed at ensuring that field procedures were followed.
Type of Research Instrument
The questionnaire was developed in English by adapting the International Crime Victimization Survey (ICVS) questionnaire. Prior to the main survey, the questionnaire was pretested.
Ghana Statistical Service
Data editing occurred at three levels:
1. Data were validated in the field. Field editing was done by interviewers and supervisors of all questionnaires in the clusters that data were collected. Interviewers and supervisors revisited households to collect information which was either left out, uncompleted or not clear.
2. A team was engaged to do office editing. The purpose of office editing was to ensure that field data collection had conformed to the laid down principles and procedures. Necessary corrections were made if errors were found.
3. Data cleaning and imputation. This stage offered the data processing officers to run further checks that ensured consistency.
Using SPSS software, basic data consistency checks were made and the necessary gaps were rectified.
Government of Ghana
The Ghana Statistical Service as a public institution has the obligation to promote data dissemination to facilitate national development. Making mcrodata available will enable students and the academia to conduct research works, assist investors to take business decision, help the individual to evaluate and take appropriate decisions. It will also assist the government to formulate appropriate policies and programmes to facilitate national development. GSS' policy framework provides access to data through:
1. Public use files. These categories of data sets are accessible by all without any payment. They are available on-line to all interested users, for research and statistical purposes only.
2. Licensed datasets. These categories of data sets are accessible under certain conditions. Thus, prospective clients/data users may access any data based on certain conditions set by the GSS
3. Datasets only accessible on location. We consider this category as a data enclave where some data sets are only accessible at GSS offices and prospective data users and researches have to physically be available at GSS offices for further discussions before data are released. Thus, data enclave would not be linked to the outside world through our web site or other medium.
The following terms and conditions apply:
Before being granted access to the dataset, all users have to formally agree:
1. To make no copies of any files or portions of files for which access has been granted, except those authorized by GSS.
2. Not to use any technique in an attempt to identify any person, establishment, or sampling unit.
3. To hold in strictest confidence, the identification of any establishment or individual that may be inadvertently revealed in any documents or discussion, or analysis. Such inadvertent identification revealed in her/his analysis will be immediately brought to the attention of the GSS.
4. The data and other materials will not be redistributed or sold to other individuals, institutions, or organizations without the written agreement of GSS.
5. The data will be used for statistical and scientific research purposes only.
6. The data will be used solely for reporting of aggregated information, and not for investigation of specific individuals or organizations.
7. No attempt will be made to identify respondents, and no use will be made of the identity of any person or establishment discovered inadvertently. Any such discovery would immediately be reported to the GSS.
8. No attempt will be made to produce links among datasets provided by the GSS with other datasets that could identify individuals or organizations.
9. Any books, articles, conference papers, theses, dissertations, reports, or other publications that employ data obtained from the GSS would cite the source of data in accordance with the citation statement provided with the dataset
10. An electronic copy of all reports and publications based on the requested data will be sent to the GSS.
