This is the first Transport Indicators Household Survey conducted by the Statistical Service in collaboration with the Ministry of Transport as part of the Transport Indicators Database Project Phase I.
The survey was conducted by the Statistical Service in collaboration with the Ministry of Transportation and was funded by the Danish International Development Agency (DANIDA).
The main objective of the survey was to derive reliable estimates of indicators relevant to the transport industry in the country. The survey covered a total of 6,000 households selected from 400 Enueration Areas (EAs) across the country. The survey collected information on the demographic characteristics of the household members including age, sex, level of education and employment status. More detailed information was collected on the modes of transport used to school, hospital/clinic, market places, etc. Information was also collected on the waiting time at bus stops, time taken to travel and from school, hospital/clinics, etc. and the cost of travel.
Questions were also asked about the kind of difficulties household members faced in the use of the various modes of transport.

Provided funding for the survey
A sample of 6,000 households was selected from 400 Enumeration Areas (EAs) for the survey. The frame from which the sample was selected was based on the 2000 Population and Housing Census. The frame was stratified into urban/rural and the 10 administrative regions of the country before sample selection.
The sample was selected in two stages. The first stage involved the systematic selection of 400 EAs with probability proportional to size, the measure of size being the number of households in an EA. The second stage involved the selection of 20 households from each selected EA. The first 15 households selected in each EA were interviewed and the extra 5 households served as backup for replacement in case of a non-response or the absence of a selected household.
Deviations from the Sample Design
The survey was implemented according to the Sample Design. The only difference from other surveys was that households which could not be located were replaced.
Sample eights were calculated for eac Enumeraion Area for the computation of estimates for the entire population. These were adjusted by the number of households successfully interviewed using the household listing done for the survey.
Dates of Data Collection
Data Collection Mode
There were 12 teams formed for the data collection made up of a supervisor and three interviewers. The role of the supervisor was to arrange for the interviewers to meet the selected households for the interview. For each enumeration area, the supervisor met with the community leaders to explain to them the purpose of the data collection exercise. He/She was also required to review the completed questionnaires for each interviewer.
There were field visits by members of the project implementing team to check the work of the teams and also assist in resolving any problems in the field.
Data Collection Notes
There was a pre-testing of the questionnaire after the compilation and review of the indicators at a stakeholders' workshop.
A 10-day residential training workshop was organized for the field personnel. The training involved lectures on interviewing techniques, understanding of concepts and definitions, mock interviews and field practice.
There were 12 teams formed for the fieldwork, made up of a supervisor and three interviewers. An additional team was set up to edit the questionnaires from the field before data capture. There were sessions for interview practice in the major local languages.
Interviews were conducted in English and the major languages.
The supervisor visited the locality to identifyy the selected households and arrange for the interviews. There was a meeting with the community leaders to explain the purpose of the survey before the interviews took place.
Ghana Statistical Service
The survey being part of the Trnasport Indicators Database Project, stakehoder meetings were held to identify transport sector indicators after which the questionnaire was developed. The questionnaire was further subjected to further reviews by stakeholders and pre-tested before finalization. The final questionnaire for the fieldwork was published in English.
An instruction manual was developed alongside the questionniare to guide both the supervisors and interviewers.
The completed questionnaires from the field were edited by 5 editors who were selected during the training of personnel for trhe fieldwork. They also coded some porions of the questionnaire, particlaurly occupation and industry before data capture.
Data capture was done using CSPro. A double-entry entry data capture strategy was adopted using 6 data entry operators to ensure data quality. After cleaning and validation, the data was exported into SPSS for analysis.
The data entry personnel had earler been trained alongside the field personnel to familiarize themselves with the questionnaire.
