With the transition to the planned development period in Turkey, information about structure of economically active population has started to be gathered from General Population Censuses conducted in every five years and Labour Force Surveys (LFS) being conducted since 1966. However, data obtained from these sources especially the data obtained from Labour Force Survey which is the main data source for monitoring the labour market were not comparable within a time series because of the differences on geographical areas covered, definitions, concepts, variables and classifications until 1988.
It was targeted to redesign the labor force survey to take labor market pulse on time and more correctly in the context of the project on Labour Market Information System coordinated by United Nations Development Programme (UNDP) and then in the context of World Bank Employment and Training Project with the technical assistance of International Labour Organization (ILO).
The main objective of the Household Labour Force Survey is to obtain information on the structure of the labour force in the country. This includes information on economic activity, occupation, status in employment and hours worked for employed persons; and information on the duration of unemployment and occupation sought by the unemployed.
Kind of Data
Sample survey data [ssd]
Unit of Analysis
Demographic characteristics: age, sex, marital status, place/country of birth, place/country of previous residence, educational attainment, relationship to household head
Main labour related characteristics: employment, unemployment, underemployment, hours of work, wages, informal employment, social security coverage, training received, absence from work
Population coverage: Whole population excluding the following groups: Non-settled population, persons living in institutions and conscripts (but army forces are included)
The survey covers: The usual residents present and the usual residents temporarily absent
Age coverage: The labour related questions of the survey relate to the population of age groups between 15 and 99 years old

Household Labor Force Survey is designed to produce estimations on annually, quarterly (3 months) and monthly basis over 3 months moving average by carrying out the survey at each month in the country.
Sample size of the survey is calculated in order to have annual estimations on Nuts1 x urban-rural and Nuts2 level.
For the determination of the sample size, two studies were carried out:
In the first study, the initial selection probabilities, f0, were calculated in parallel with the year of 2004. The number of households was allocated to the Nuts2xurban-rural groups (52) proportionally. Then, in order to achieve the sufficient sample size in each group, the number of households in the urban groups were weighted by 1.5*f0 and in the rural groups by f0. By this weighting, some groups had still under or over sample sizes. These groups were reweighted by f0 or 2*f0. Hence the final sample sizes from the first study were obtained.
In the second study, the requirement of Eurostat 577/98 regulation was taken into account. The instructions in this regulation were applied on the 2007 data set and the sample sizes in each strata were calculated independently. Following the regulation, firstly, %5 of the working age population was calculated and the corresponding groups belonging to this %5 of the working age population were determined. The groups were chosen from age, gender and education level groups. Then the sample sizes for each strata (52) were calculated depending on both the %8 coefficient of variation criteria and the values of unemployment rate, design effect, overlapping factors between quarters and correlation coefficient values in each of the selected age, gender and education level groups.
Number of interviewed persons 15 years of age and over: 384,846
Number of interviewed households: 143,871
Results of the household labour force survey have been weighted and published by the most recent population projections. Until year 2009 aforesaid population projections was calculated based on the general population censuses. In 2007 Address Based Population Registration System (ABPRS) was established and there exists some differences in the distribution of population by age, sex and regions in ABPRS compared to the censuses.
In this direction, the new population projections were produced using the most recent population data obtained from this new system. In this direction, national and regional population projections were renewed by the results of 2008 ABPRS and also using the results of Turkey Population and Health Survey realized by the Hacettepe University Institute of Population Studies.
New population projections have started to be used in household labour force survey results starting from January 2009 onwards and in order to obtain comparability, monthly results for 2005-2008 terms and 2004 annual results were also revised by the new population projections.

Data Collection Notes
Reference and application period
The first week of each month starting with Monday and ending with Sunday has been used as the reference period.
The field application starts after the reference week and is completed within 15 days.
Estimates of Sampling Error
Sampling errors related to proportion and total estimates of the survey are calculated based on Taylor Series approximation using SAS module.
