Main results from the Labour force survey ad-hoc module on employment of disabled people.

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.

The classifications applied in the Labour Force Survey are harmonised with the international classifications in terms of economic activities, occupations, educational attainment. The main classifications used are the following:

· 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.

All persons aged 15 years and over living in the selected non-institutional households are covered by the Labour force survey. The target population for the ad-hoc module "Employment on disabled people" consists of persons aged 15 - 64 years.

The Labour Force Survey provides estimates of the main characteristics of labour market as employment, unemployment, inactivity, occupations, economic activities, working time and other, as well as social-demographic characteristics as sex, age, place of residence (urban/rural), education etc.

The main definitions applied in the survey are in accordance with the recommendation of International Labour Organisation and EU legislation.

The results from the 2011 module allows to estimate:

• The number of persons with health problems and difficulties in basic activities (difficulties in seeing, hearing, walking, etc.);
• The number of persons with limitations in work caused by health problems/difficulties in basic activities;
• Special assistance needed or used by people with health problems/difficulties in basic activities;
• Limitations in work because of other reasons (family/care responsibilities, lack of qualification/experience, lack of transport etc.).

The ad-hoc module "Employment of disabled people" covers all compulsory variables according Commission Regulation (EC) No 317/2010 of 16 April 2010 adopting the specifications of the 2011 ad-hoc module on employment of disabled people.

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).
The ad-hoc module on disabled people was carried out over a part (25%) of LFS sample in each quarter and consisted of the households from the third wave. Due to the sampling approach used in the labour force survey, the estimation of the parameters obtained from the labour force survey could vary from those in the population due to sampling errors, errors due to non-response, errors in registration or processing etc.

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).

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.

Comparability across EU Member States is considered high due to use of harmonised concepts, variables, definitions and classifications.

Some of the totals (rows and columns) in tables could slightly differ from the sum of the components because of the rounding of figures.

The average duration of interview on the ad-hoc module is about 10 minutes.

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.

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.

Once

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.
