Series Information
The 2009 Crime Victimization Survey (CVS) was the first to be conducted. It was a pilot study designed to facilitate a broader understanding of the crime problem as well as a better assessment of its burden on citizens in four Metropolitan Areas in Ghana. The four areas were Accra, Kumasi, Sekondi-Takoradi and Tamale Metropolitan Assemblies. The CVS is a household survey programme conducted by GSS, with funding from United Nations Office on Drug and Crime (UNODC).
The United Nations Office on Drugs and Crime (UNODC) initiative Data for Africa has the overall objective to improve the knowledge of drugs and crime problems in Africa, by strengthening the capacity of African countries to collect and analyse data and trends in drugs, crime and victimization.
While in the past only police and criminal justice data were used to measure crime, it is widely accepted that such information alone is not sufficient and should be complemented with victimization survey results. Thus, the survey was to assist Ghana in filling data gaps for monitoring the crime situation in the surveyed areas.
For the first time, the survey enabled Ghana to generate household-based crime indicators and set baselines for many other statistics and indicators.

Abstract
Background
The 2009 Crime Victimization Survey in Ghana was a household survey carried out in four Metropolitan Areas - Sekondi-Takoradi, Accra, Kumasi and Tamale Metropolitan Areas. It was a pilot study designed to facilitate a broader understanding of crime and its burden on the citizenry. While in the past only police and criminal justice data were used to measure crime, it is now widely accepted that such information alone is not sufficient and should be complemented with victimization survey results.
During the survey, interviews were conducted among a representative sample of the population in the four areas. People were asked whether or not they have been victims of crime in the past five years. Different crime areas were considered in the survey.
Objective
The main objective of the study is to collect information on citizens' first hand experiences in crime and criminal justice. The specific objectives are:
Promoting community and victim centered crime prevention strategies
Providing accurate and reliable information as the basis for the development of national policies as well as internationally
comparable crime and criminal justice data databases
Improve police-community relations by:
(a) Revealing the propensity to report crimes
(b) Exploring the level of satisfaction with the patrolling activities upon report
(c) Increasing the use of individual and household crime prevention measures
Building the capacity of Ghana Statistical Service in conducting crime victimization survey.
Sample design
The population in individual households that dwell in living quarters in each of the four Metropolitan Assemblies constituted the sampling 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.
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. 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.
Content
The questionnaire used in the survey to collect information on household members, included the following crimes:
Motor vehicle theft (car, motor cycle and bicycle)
Car hijacking/attempted car hijacking
Burglary/attempted burglary (break and enter)
Robbery/attempted robbery
Personal theft
Sexual offences
Kidnapping
Consumer fraud
Corruption
The questions related to crimes that either the respondent or any member of his/her household has experienced over the past five years (i.e. since January 1, 2004).

Sampling
Sampling Procedure
The 2009 Crime Victimization Survey was held in four Metropolitan Assemblies in Ghana: Sekondi-Takoradi, Accra, Kumasi and Tamale Metropolitan. 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.
The population of interest was all household members aged 16 years and older. Among these household members, the individual who was next to celebrate his/her birthday was selected for the interview.

Data Processing
Data Editing
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.

Other Processing
Capturing of the questionnaires was automated. The questionnaires were converted into scannable format using Teleform automated data capture software. The questionnaires were then printed after several tests had been conducted to make sure that the database had captured all the variables in the questionnaire. This helped to speed up the data capture and reduce data entry errors during processing of the data.
Before scanning using Teleform, manual edits were performed on the questionnaires received from the field to check for completeness and accuracy of the household questionnaire. After the scanning exercise, structural edits were done followed by consistency checks to further reduce errors.
Data were captured, cleaned and edited in MS Access format and transferred to SPSS. Further cleaning and imputations were done during analysis where the information was found to be contradictory or incomplete.
Data processing commenced on the 15th December, 2009 and ended on 4th January, 2010.
