Sampling design & procedure
Sampling design (scheme; simple random sample, two stage stratified sample, etc.) Base used for the sample (sampling frame)  Last update of the sampling frame (continuously updated or date of the last update) Primary sampling unit (PSU)   Final sampling unit (FSU)
Two stage stratified cluster sampling involving eight subsamples. National Address Database which is based on Adress Based Population Register System is used as the sampling frame. National Address Database consists of all adresses up to indoor numbers and updated at any moment (continuosly) by the municipalities. Blocks. Each block consists of approximately 100 households  (between 80 and 120). First stage sample selection is realized by using the frame of blocks. Household address

 

Sampling design & procedure
First (and intermediate) stage sampling method   Final stage sampling method Stratification (variable used) Number of strata (if strata change quarterly, refer to Q4). Rotation scheme (2-2-2, 5, 6, etc.)
Primary sampling units (blocks) are selected with probability proportional to their household sizes from Province X Urban/Rural classes.  Selection of the second stage units (household addresses) are based on the rotation pattern. When the PSU's are firstly entered to the sample, 20 households are selected systematically and divided into two parts namely the sets A and B.  Every quarter 10 of those (one set A or B) are involved in the survey. At the first stage of sampling, the implicit strata are defined as 81 provinces and urban-rural areas. An urban area is defined as a settlement with more than 20 000 inhabitant, rural area is defined as a settlement with less than 20 000 inhabitant based on current Address Based Population Register System. 162 (81 provinces and urban-rural areas) 2-2-2

Brief description of the method of calculating the quarterly core weights Is the sample population in private households expanded to the reference population in private households? (Y/N) If No, please explain which population is used as reference population Gender is used in weighting (Y/N) Which age groups are used in the weighting (e.g., 0-14, 15-19, ..., 70-74, 75+)? Which regional breakdown is used in the weighting (e.g. NUTS 3)? Other weighting dimensions
The following weighting steps are calculated; The procedure takes into account the data of the related 3 months. Moving average procedure is applied, so each month, the weights of aggregate 3 month data are calculated. At the first step (design weights) initial weights are calculated inversely proportional to their selection probabilities (pps at the fist stage, systematic at the second stage) and assigned to each sampling unit.  At the second step, nonresponse adjustment (excluding the out of scope units with their weights) of households is applied on the basis of blocks, thus initial weights are adjusted for non-response. At the next step, in order to estimate quarterly LFS results, the  weights are calibrated by the "15th of middle month projections" based on Address Based Population Register. In the procedure, integrated calibration method is applied. Also trimming procedure is applied to avoid the use of extreme weights. In the calibration, "NUTS 2 by urban-rural" and  "age group by sex" distributions are adjusted iteratively. Finally an adjustment by register distrubition of household size is applied.  N Non-institutional middle of the year population projections based on Address Based Population Register. Y 0-4, 5-11, 12-14, 15-17, 18-20, 21-24, 25-29, 30-34, 35-39, 40-44, 45-49, 50-54, 55-59, 60-64, 65-74, 75+ NUTS 3 Urban and rural areas, household size distribution

 

Brief description of the method of calculating the yearly weights (please indicate if subsampling is applied to survey yearly variables) Gender is used in weighting (Y/N) Which age groups are used in the weighting (e.g., 0-14, 15-19, ..., 70-74, 75+)? Which regional breakdown is used in the weighting (e.g. NUTS 3)? Other weighting dimensions
In the calculation of yearly weights, the initial weights adjusted by the nonresponse of each month which were already calculated during the year are defined as the input weights  in the calibration procedure.  After bringing together all data the weights are calibrated by the "1st of July of the related year projections" based on Address Based Population Register. Integrated calibration method is applied in the procedure. Also trimming procedure is applied to avoid the use of extreme weights. In the calibration, "NUTS 3 by urban-rural" and  "age group by sex" distributions are adjusted iteratively. Finally an adjustment by register distrubition of household size is applied.  Y 0-4, 5-11, 12-14, 15-17, 18-20, 21-24, 25-29, 30-34, 35-39, 40-44, 45-49, 50-54, 55-59, 60-64, 65-74, 75+ NUTS 3 Urban and rural areas, household size distribution

 

Brief description of the method of calculating the weights for households External reference for number of households etc.? Which factors at household level are used in the weighting (number of households, household size, household composition, etc.) Which factors at individual level are used in the weighting (gender, age, regional breakdown etc.) Identical household weights for all household members? (Y/N)
Household adress is the final sampling unit selected for the LFS. Depending on the sampling design explained above, the weighting procedures are applied. We have additional adjustment by the distribution of number of households of Address Based Population Register (ADNKS) information. However this adjustment does not exactly ensure the number of households of register distribution. The reason for this is, after multiplying the weights externally with the ratio of the number of households on the basis of register household size distribution, the final adjustment step ends with the population distribution by nuts3xurban/rural ratios.

Assessment of the relevance of the main LFS statistics at national level (e.g. for policy makers, other stakeholders, media and academic research)
The aim of the survey is to reveal clearly the status of the population in terms of labor,  to compile detailed information about employment and unemployment and to offer them to the public for the usage of determinants of economic policies and reviewers of country's economy.

NUTS level of detail   
Regional level of an individual record (person) in the national data set Lowest regional level of the results published by NSI Lowest regional level of the results delivered to researchers by NSI Brief description of the method which is used to produce NUTS-3 unemployment and labour force data sent to Eurostat?
NUTS 3 and further details (province, district etc.) are kept in the original national data set, but these information is neither published nor given to the users since sample is not representative at NUTS 3 level. Estimation level is NUTS 2 for LFS (at annual basis).

At NUTS 3 level; only LFPR, employment&unemployment rate was published between 2008 and 2013 using small area estimation methods. In 2011 these indicators will not be published from LFS, since 2011 Census results will serve more detailed information on employment and unemployment at NUTS 3 level.		 At micro data only NUTS 2 codes are given. NUTS 3 level results have not sent to Eurostat (published with a press release at national level between 2008 and 2013) since it is not in line with the requested detail (no age and sex breakdown). However, it is available at the TURKSTAT website and also might be sent if it is requested.

The main labour force indicators at provincial level could not be estimated statistically significant because of transition to the continuous labour force survey covering every weeks of the year as reference period (52 weeks) and also the change on urban-rural distinction since 2014. So, it has been decided not to publish related press release considering the misleading results for decision makers.

NUTS3 level main indicators (LFPR, employment and unemployment rates) were calculated by the method “Empirical Best Linear Unbiased Predictor” (EBLUP) based on SAE methods. This method depends on using selected external variables (province populations and other demographic indicators, Social Security Institution data, Turkish Employment Office data etc.) besides the direct LFS estimations and standard errors. The province level results obtained from this study are very close to the original results directly calculated from the survey as the sample size is big enough for the province level estimations, while the sample size is not enough for the province level estimations, the estimation is determined predominantly by the external variables. Detailed methodology could be reached from the web site.

Briefly the study was implemented mainly in three stages:
1. Direct estimation at province level and the calculation of related standard errors by using LFS data. Calculation of direct standard errors is based on JRR approach and  takes into account the srs variance, kish factor, overlapping factor and nuts1 level design effects.
2. The determination of the variables for the model by using external data sources.
3. The calculation of the composite estimates.

Description of the assumption underlying the denominator for the calculation of the CV for the employment rate
In Turkstat for employment totals and rates, we have different cv values. We apply proc survey means sas module which is based on Taylor approach. We take into account the calculation formulas of standard deviation formula for the total estimates and the standard error formula for the mean estimates  of the indicators required in the table.

Y Y N Seasonal adjustment of Labour Force Statistics carries out by using TRAMO-SEATS methodology based on ARIMA (Autoregressive Integrated Moving Average) model estimation developed by the Banco de Espana and also suggested by Eurostat. The software that is used for the application of this method  is TRAMO-SEATS for Windows (TSW). Seasonally adjusted figures of labour force statistics have been produced by indirect approach. Namely, labour force, employed persons according to economic activities and unemployed persons are firstly seasonally adjusted and then aggregated to derive seasonally adjusted employment and unemployment rates.

Coherence of LFS data with Business statistics data    
  Description of difference in concept Description of difference in measurement Give an assessment of the effects of the differences Give references to description of differences
Total employment Business statistics data mainly cover registered employment while the rate of people who are employed without any social security is though high in Turkey. LFS also covers unregistered employed. Thus, it is not possible to compare total employment figures gathered from LFS and business statistics. To make correct comparision registered employed should be selected from LFS also. SBS surveys also do not cover the following activities in Turkey case (According to NACE Rev 1.1);
Section A - Agriculture, Hunting and Forestry,
Section B - Fishing,
Section L - Public Administration and Defence; Compulsory  Social Security,
Section P - Activities of Household,
Section Q - Extra Territorial Organizations and Bodies,
Section O - A part of the section O (except 91-Activities of Membership Organisation N.E.C.).		 Main difference in measurement comes from the reference terms. While business statistics cover long reference periods, LFS uses only one week as reference. Effect is very high in total since 32,2 % of total non-agricultural employment is unregistered and unregistered part of the employment mostly could not be captured by the business surveys. NA
Total employment by NACE In some institutionalized sectors (mining, electricty, gas and water, education, health etc.) rate of unregistered employed is very low and results are more comparable. But, for example in manufacturing sector the rate of unregistered employment is very high and these data are not coherent.  SBS does not cover all activities as described in concept difference. Effect differs among sectors as explained in the concept. In institutionalized sectors effect of the difference is lower than other sectors. NA
Number of hours worked No significant difference in the calculation of number of hours worked. NA NA NA

 

Coherence of LFS data with registered unemployment  
Description of difference in concept Description of difference in measurement Give references to description of differences
People who apply to Employment Office (ISKUR) to find a job and has no job at that moment in the minimum wage level are considered as unemployed and the application is kept in the registers during one year unless a job is found for him/her. After one year this application is dropped out  (people may apply again). Measurement methods are completely different. In LFS people even worked under the minimum wage (unregistered people) are considered as employed.  NA

 

Assessment of the effect of differences of LFS unemployment and registered unemployment     
Give an assessment of the effects of the differences          
Overall effect Men under 25 years Men 25 years and over Women under 25 years Women 25 years and over Regional distribution (NUTS-3)
Total number of registered unemployed is lower when compared with the LFS results altough it covers the one year (registered unemployed was around 2.1 million at the end of 2015, while number of unemployed at annual basis was 3.6 million according to the LFS results). The main reason is the lack of legal requirement for unemployed people to register themselves to ISKUR. Also, the coverage of unemployment benefits is limited in Turkey. In order to receive unemployment benefits from ISKUR, it is necessary to work before (at least 600 days during the last three-year period) and only people who was dismissed by the employer could receive unemployment benefits. Difference exists in all groups without any significant disparity. Difference exists in all groups without any significant disparity.

8.5. Coherence - National Accounts
Coherence of LFS data with National Accounts data    
  Description of difference in concept Description of difference in measurement Give an assessment of the effects of the differences Give references to description of differences
Total employment 1) Labour force statistics do not cover conscripts (since they're not covered as household member during their compulsory military service), but ESA includes conscripts under the general government services,
2) Non-residents working with resident producer units (not included in labour force statistics but included in employment as defined in the ESA),
3) A correction for regular employees on temporary leave is made in National Accounts data (LFS covers these regular employees as employed if total duration of absence is less than 3 months or they're continuing to receive 50% or more of their wage and salary).		 National Accounts employment data has three components. 1- LFS (persons at work during the reference week), 2- ESA95 requirements are also covered in NA employment data. Such as; -foreign civilans settled in the country for a period of one year or more, - soldiers, - foreign military personel working with international military organizations located within the geoagraphic territory of the country,-  members of the country's armed forces stationed in the rest of the world,- civil cervants who are working as a staff of diplomatic mission on abroad. 3- Secondary jobs. National Accounts employment data basicly based on LFS. In addition another data sources were  used by NA. Such as, Social Security Institutions, Ministry of Defence, Ministry of Froeign Affairs etc.  There is no big difference between  LFS and National Accounts data. UNA
Total employment by NACE No big difference No big difference  UNA UNA
Number of hours worked In NA;
1) Jobs = employed persons – employed persons who are not at work during the reference week + secondary jobs
2) Total hours worked = number of jobs x actual hours per job		 No big difference  UNA  UNA

 

Which is the use of LFS data for National Account Data?   
Country uses LFS as the only source for employment in national accounts. Country uses mainly LFS, but replacing it in a few industries (or labour status), on a case-by-case basis Country not make use of LFS, or makes minimal use of it Country combines sources for labour supply and demand giving precedence to labour supply sources (i.e. LFS) Country combines sources for labour supply and demand not giving precedence to any labour side Country combines sources for labour supply and demand giving precedence to labour demand sources (i.e. employment registers and/or enterprise surveys)
