The Household Budget Survey (HBS) is a study of household expenditure patterns over a period of time (usually one year). The 2006/2007 HBS is the latest in a series of similar surveys conducted by the National Statistics Bureau (NSB) between 1973 and 2000. The interval between surveys has varied from 5 to 7 years, and this is the 6th of its kind conducted in Seychelles.
The 2006-2007 Household Budget Survey (HBS) was conducted between May 2006 to July 2007 and its primary purpose was to update the information on the expenditure pattern of households. The data would then be used to compile a new consumer’s ‘basket of goods’ and revise the weights used in the compilation of the monthly Consumer Price Index and the measurement of inflation. The data have also been used in the estimation of household consumption contribution in the GDP, the average monthly household expenditure and income and also in the compilation of new poverty indicators.
Around 1200 households on Mahe, Praslin and La Digue (the 3 main islands in Seychelles) participated in the survey, each of them providing data over a period of 1 week. In the final analysis, data from 1164 households and 4323 individuals have been included.

A list of households from the earlier mapping exercise provided the most up-to-date sampling frame for the survey. The frame comprised of 22,831 households listed by district and enumeration area. The households served as direct sampling units.
Stratified, systematic random sampling was adopted for the selection of households with the electoral districts serving as strata. The number of households to be selected from each district was determined by proportional allocation based on size (number of households). The target sample was 1200 households which would represent a little over 5% of all households, but an initial 1511 households were selected to account for non-response and households deemed non-eligible to participate in the survey.
The selected sample listed a total of 1511 households, of which some 1300 were interviewed. The survey design over-sampled households by 25% to take into consideration non-response. 222 of the selected households (18.5% of the desired sample) either refused to participate in the survey or were not available. The 100 or so additional households were interviewed to replace the households that had completed only part of the survey. Those included households that agreed to be interviewed but refused to complete the account book.

Data Collection Notes
The field work started in May 2006 and was completed at the end of July 2007. There were two periods of interruption during the data collection phase. The first one lasted 4 weeks (July 2006) during which the presidential elections were being held, and the second lasted 2 weeks during the busy festive season between the last week in 2006 and the first week in 2007.
Households were requested to keep the diary of daily expenditure for one week (Monday to Sunday). Other purchases made on a regular
The pilot survey to test the questionnaire and assess public response was conducted in mid-May 2006. The exercise was also used as part of the survey training program for field staff who would be participating in the exercise for the first time, and also to assess the logistics of the survey.
Households were interviewed at the beginning of each week and each household was asked to keep a detailed account of their expenditure for a week. Five enumerators interviewed 5 households each per week. The questionnaires were then revised and edited where appropriate, based on comments, suggestions and weaknesses identified during the pilot survey.
Method of Data Collection
The data were collected using personal interview method. The interview was followed by 2 to 3 additional visits during the diarykeeping week. Recruitment of households was done every week and each interviewer was required to interview at least 3 households per week.
Initially, it was planned that the data would be collected over 6 months. However, after consideration it became evident that the targeted number of households would not be covered with the given staff and resources. It was decided that the survey period be extended to ensure the desired coverage was attained.

The questionnaire comprised of four main parts. Form HBS 1 was the household schedule and contained questions relating to household members’ demographic details, economic status as well as household facilities and selected major expenditure.
Form HBS 2 contained questions addressed to individual members of the household aged 15 years or more. This section covered questions related to personal and business income. The third section of the questionnaire (HBS 3) was the diary or account book in which households were asked to record details on daily expenditure and Form HBS 4 was completed in circumstances of nonresponse.
The data were captured on personal computers using a programme written in DELPHI. The various software used to analyse the data at different stages included FoxPro, MS EXCEL and SPSS.
A total of 4790 persons from 1300 households were interviewed. However, in the analysis of expenditure, data for 1164 households and 4323 individuals were included and the remaining was not considered on account of incompleteness of significant parts of the questionnaire.
