    Income/Expenditure/Household Survey [hh/ies]
    Series Information

    The Household Income and Expenditure Survey (HIES) is conducted every 5 years. The first HIES survey was conducted in 1997 and the fifth survey was conducted in 2023.
    Abstract

    The 2018 HIES is the fifth such survey conducted by the Samoa Bureau of Statistics since the first one in 1997. The 2018 Household Income and Expenditure Survey (HIES) was conducted in four rounds within a twelve month period from February to November 2018.

    The 2018 HIES collected information on Income and Expenditure of sampled households in order to provide information on the economic characteristics of all households in Samoa. The main objectives of the survey are:

    1. CPI Re-base: To obtain expenditure weights, review the “basket of goods and services,” understand where consumers purchase goods and services, and other useful data for the revision of the Consumer Price Index.
    2. Hardship Analysis: To provide data to determine the extent of hardship and vulnerability of households in Samoa.
    3. National Accounts: To supplement the data available for use in compiling official estimates of household accounts in the systems of national accounts.
