    Abstract

    Turkey Household Income and Consumption Expenditures Survey (HICES) started in Turkey in 1987. Since 2002 it has been conducted annually. The survey is one of the major sources that provide information on the socio-economic structures, living standards and consumption patterns of the households in Turkey.

    Turkey HICES has the following objectives:

    • obtain weights to calculate Consumer Price Index,
    • monitor changes that occur in the consumption patterns of the households over time,
    • compile data to estimate consumption expenditures for the National Accounts,
    • determine poverty line and obtain other socio-economic indicators,
    • obtain data required for studies on minimum wage determination.

    Sampling

    Sampling Procedure

    The survey sample was stratified on two different levels. The first level of stratification was seven geographical regions of Turkey. The second one divided the regions into eight residential units by population stratum:
    a. 0-2,000 inhabitants,
    b. 2,000-5,000 inhabitants,
    c. 5,000-10,000 inhabitants,
    d. 10,000-20,000 inhabitants,
    e. 20,000-50,000 inhabitants,
    f. 50,000-100,000 inhabitants,
    g. 100,000-150,000 inhabitants,
    h. above 150,000 inhabitants.

    At the next stage, households were clustered in groups of 30 within each population stratum. Random selection of clusters proportionate to their size in population determined the sample size as 8,000. This number was then reduced to 4,000 due to budget constraints. For this reduction, clusters stripped off their stratum information were randomly numbered and only half of them were selected. After the selection, the clusters were reassigned their respective stratum information. To compensate for possible missing data due to non-response, the final sample size was decided to be 4,300.

    Data Collection Notes

    The household data was collected in face-to-face interviews and all the information was recorded on paper with pencil. The average administration of a household questionnaire took 90 minutes. However, the household size and how many of sections applied to the members were important factors affecting the duration of the interview. In addition, the richer the household the longer it took to calculate household consumption expenditure, which significantly changed the length of the interview. Also, the interviewers observed that questions that required detailed recall of expenditures bored and tired the respondents, which made the interviewers' job harder.

    Due to hard budget constraints, the sample households were not visited on a regular basis to collect recordings of periodical consumption and income. 2001 HICES consultants visited the households once and data collection was based on the recall method, which is subject to telescoping errors, i.e. the failure of respondents to recall expenditures and income accurately, causing possible underestimation of figures. A comparison of consumption and income aggregates to data from national accounts was made for 1987 and 1994 HICES and 2001 HICES, which showed that the level of underestimation of expenditures and income of 2001 survey was not critical.
