Abstract
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.

Sampling
Sampling Procedure
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.
Weighting
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.
