The Labour Force Survey is a sample statistical survey carried out through households. The main purpose of the survey is to provide data on labour status of population aged 15 years and over and for the main characteristics of employed, unemployed and persons out of labour force in the Republic of Bulgaria. In 2011 an ad-hoc module on disabled people was incorporated in the regular Labour force survey.

· International Standard Classification of Education, 1997 version (ISCED 1997);
· Classification of Economic Activities (CEA-2008, for international use NACE.BG 2008) - since 2008;
· National Classification of Occupations and Duties-2005 (NCOD-2005) (1st digit - occupational class), comparable to the International Standard Classification of Occupations - ISCO'88 - until 2010;
· National Classification of Occupations and Duties-2011 (NCOD-2011) (1st digit - occupational class), comparable to the International Standard Classification of Occupations - ISCO'08 - since 1 January 2011;
· International classification of professional status - ICSE-93;
· Classification of Territorial Units for Statistical Purposes in Bulgaria - NUTS.

|Accuracy and reliability|
The sample used for the Labour Force Survey is a two-stage stratified cluster sample which includes quarterly about 19.5 thousand households (representing about 0.65% sampling rate).
Coefficients of variation (relative standard errors), and confidence intervals (i.e. the range of values that 95% of times would capture the true value in the population) are calculated for assessment of stochastic reliability of the estimates for main indicators.
The non-response rate for the ad-hoc module "Employment of disabled people" is 2.7% (from persons responded in regular LFS).
|Timeliness and punctuality|
Generally the main results from the LFS ad-hoc modules are published about 4-5 months after the reference year.
The results from the ad-hoc module "Employment of disabled people" were presented on 15 May 2012, according to the Release Calendar presenting the results of the statistical surveys carried out by the National Statistical Institute.
|Coherence and comparability|
|Comparability - geographical|
Comparability across EU Member States is considered high due to use of harmonised concepts, variables, definitions and classifications.
|Comparability - over time|
|Coherence - cross domain|
|Coherence - internal|
Some of the totals (rows and columns) in tables could slightly differ from the sum of the components because of the rounding of figures.
|Cost and burden|
The average duration of interview on the ad-hoc module is about 10 minutes.
|Data revision - policy|
Revisions of previously released data are usually not performed. By exception revisions may happen after new estimates of population from a population census became available.
|Data revision - practice|
Revised micro-data on 2011 ad-hoc module (due to the new population estimates based on 2011 Census and changes in weighting procedure) were provided to Eurostat. Consequently the data from the ad-hoc module published by Eurostat could slightly differ from the published national data.
Ad-hoc module integrated with the Labour force survey.
|Frequency of data collection|
Data are collected through paper questionnaire and personal interview with persons (aged 15 - 64) from the selected households.
Plausibility checks are performed during the data entry. Additional consistency checks are carried out before publishing of data.
The completed questionnaires are coded (for economic activity, occupation, place of work, field of education etc.) and entered into computer in NSI regional offices. Data files are sent to NSI, where additional control and weighting is doing. Data are aggregated by different variables (characteristics), tabulated and disseminated.
