Household Budget Survey 2017, Mauritius - Mauritius

Abstract

Statistics Mauritius conducts the Household Budget Survey to collect data on the consumption patterns of the population living in private households in Mauritius. The data is used to update the "basket of goods and services" for the compilation of Mauritius' Consumer Price Index. Following the recommendation of an IMF mission in 2008, the coverage of the Household Budget Survey was extended to include private households of foreign citizens living in the country.

A stratified two-stage sampling design was used for the purpose of this survey. Clusters containing more than 50 households were stratified by geographical district and within each district by region (according to their level of relative development). At the first stage, a sample of clusters was selected within each stratum with probability proportional to size. The household within each selected cluster were stratified according to household size, expenditure class and religion. At the second stage, 8 households were sampled from each selected cluster. The total sample size was 6,720 private households surveyed at the rate of 560 per month.

抽样程序

本次调查采用了分层两阶段抽样设计。将包含50户以上家庭的集群按地理区域分层，并在每个区域内根据相对发展水平进一步按地区分层。在第一阶段，每个层内根据规模比例随机选取样本集群。在每个选定的集群内，家庭根据家庭规模、支出类别和宗教信仰进行分层。在第二阶段，从每个选定的集群中抽取8户家庭。总样本量为6,720户私人家庭，每月调查560户。
