Income/Expenditure/Household Survey [hh/ies]
The Survey on Income and Living to Conditions using “panel survey” technique has been conducted in Turkey since 2006 in order to identify the distribution of income among households and household members, to measure and profile social exclusion and poverty through an income perspective.
This study, introduced as part of the European Union harmonisation efforts, aims to produce data on income distribution, relative poverty by income, living conditions and social exclusion comparable with European Union member states. The study which uses a panel survey method is repeated every year and monitors sample household members for four years. Study attempts to obtain two datasets every year, cross- sectional and panel data.
The Survey on Income and Living Conditions, introduced as part of the European Union harmonisation efforts, aims to produce data on income distribution, relative poverty by income, living conditions and social exclusion comparable with European Union member states. The study which uses a panel survey method is repeated every year and monitors sample of household members for four years. Every year, the study attempts to obtain two datasets: cross-sectional and panel.
The Income and Living Conditions Survey 2010 has been conducted to provide annual and regular cross-sectional data to answer questions such as:
- How equally is the income in the country distributed and how has it changed as compared to the previous years?
- How many poor people are there in the country and how do they distribute across regions? How has this situation changed as compared to the previous years?
- Who is poor? Has there been a change over time?
- How has this gap between the poor and the rich evolved over time?
- What kind of a change or transition occurs in the incomes of individuals and households? How does the direction of this change depends on characteristics and circumstances, does it decline or grow?
- How is the income distributed across sectors, types of income and household characteristics?
- How do people's living conditions change or improve over time?
- The study also aims to provide panel data to calculate indicators such as persistent income poverty and to measure net changes over time.
The cross-sectional database 2010 is documented here.

Sampling
Sampling method: Stratified, multi-stage, clustered sampling.
Sampling unit: Household.
Sampling framework: Sampling framework has been derived from 2 sources:
- For the settlements with municipal status; General Building Census conducted in 2000 by TurkStat and Numbering Study (conducted in 2000) Form Population 1 data have been used.
- For the settlements without municipal status (Villages); data of General Population Census conducted in 2000 have been used to select the blocks which constituted the sampling unit of the first stage.
Selection of sample households: for the purposes of the study which used a two-staged sampling design; entire Turkey has been divided into blocks which covered 100 households each.
- At the first stage, blocks were selected as the first stage sampling unit
- At the second stage, households were selected from among the previously selected blocks as the final sampling unit. Prior to the selection of sample households, addresses at the blocks were updated through an "address screening study"
Sample size: Annual sampling size is 13,414 households in respect of the estimation, objectives and targeted variables of the study and in consideration of the attritions in the sample.
Substitution principle: Substitution has not been used as the sample size had been calculated by taking account of non-response.
Weighting coefficients used for producing population estimations from survey data are calculated based on relevant year's population projections revised by Address Based Population Registration System.
Survey instrument
-
Household registry form:
The form filled at the beginning of the survey provides brief information on access to the address of the household, condition of the household and of the survey. Moreover, following the first field application, modalities are identified for filling in the monitoring forms if the households included in the panel survey move home. -
Personal registry form:
These forms aim to identify basic demographic characteristics of the household members, changes that occur in the status of household membership of the individuals included in the panel survey, reasons for their leaving the household, the date of their departure etc. as well as individuals who join the household. -
Household and personal follow-up form:
There is need for following up the households which have moved home and the sample individuals who have left the household to join or found another one. Household and personal follow-up forms are used to identify their new addresses and access their contact information. -
Household questionnaire:
These forms attempt to collect information on the type of the occupied dwelling, status of ownership, information relating to the dwelling (number of rooms, the space actually used, heating system, dwelling facilities, goods owned etc), problems of the dwelling of the neighbourhood, status of indebtedness, rent payments, expenditures for the dwelling, the extent to which households are able to meet their general economic and basic needs and incomes earned at household level. -
Personal questionnaire:
These forms attempt to collect information on education, health, employment and marital status of the household members aged 15 and over, as well as the dates of employment and incomes earned during the reference year.
Data collection
| Start | End |
|---|---|
| 2010 | 2010 |
Income and Living Conditions Survey is repeated every year. Data compilation is done from April to July at 2 stages:
- At the first stage, interviews are conducted with the households who continue to live in the same address as in the previous application, and with the households who have newly joined the sample.
- At the second stage, interviews are conducted with the households who have moved home and therefore couldn’t be contacted at the first stage, and with the sample individuals who have left the household and founded a new one.
Surveys are carried out with face-to-face interviews and with data registration softwares installed to portable computers (CAPI – computer-assisted personal interview). Field surveys are carried out by the regional directorates of TurkStat and use team members like pollsters, controllers, organisers and technical officers. In the course of the field survey, organisational units in the field and central organisational units work in a coordinated manner which enables a successful completion of data compilation and analysis.
Prior to the data compilation, households are sent letters to inform them of the survey, its objectives, methods and time.
