Main results from the Labour force survey ad-hoc module on self-employment.

The Labor 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 2017 an ad-hoc module on self-employment was incorporated in the regular Labour force survey.

The 2017 ad-hoc module provides statistical information about the self-employed persons - number and importance of clients, influence over working time, reasons for becoming self-employed, main difficulties in work etc., as well as information allowing comparison between employees and self-employed persons in regard of satisfaction and autonomy of their work.

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

• Classification of Economic Activities - 2008, which is a Bulgarian version of NACE, Rev. 2 -  since 2008;
• National Classification of Occupations - 2011 (1st digit - occupational class), comparable to the International Standard Classification of Occupations – ISCO ’08 -  since 1 January 2011;
• International Classification of Status in Employment - ICSE-93;
• Classification of Territorial Units for Statistical Purposes in Bulgaria, harmonized with the European Classification of Territorial Units for Statistics - 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 "Self -employment" consists of employed persons.

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 Organization (ILO) and EU legislation.

Employed are persons aged 15 and over who during the reference period:

- performed some work for at least one hour for pay in cash or in kind or other income;

- did not work but had a job or an enterprise, a business from which they were temporarily absent due to illness, annual leave, full-paid maternity leave, parental leave, strike or another labour dispute, etc.

Professional status. According to professional status the employed persons are classified in the following categories:

• employers - persons who work in their own enterprise, business, farm, professional practice and  employ at least one other person;
• self-employed  - persons who work in their own enterprise, business, farm, professional practice and do not employ any other person;
• employees - persons who work for a public or private employer and who receive wages (salaries), fees, remuneration by civil contract etc.;
• unpaid family workers - persons who work without pay in an enterprise, farm, owned and operated by a relative of the same households.

Economic activity. Economic activity is defined by the type of production or services provided by the local units of an enterprise, where a person works. Employed persons are classified by economic activity according to the Classification of Economic Activities - 2008, in force since 2008, which is comparable to NACE, Rev. 2. Aggregated economic activity groupings according to nomenclature A21 are used.

Economic sectors. The employed are classified by economic sectors by aggregating the data by economic activity as follows:

• The Agriculture and forestry sector includes Agriculture, hunting, forestry and Fishing;
• The Industry sector includes Mining and quarrying, Manufacturing, Electricity, gas , steam and air conditioning supply, Water supply, sewerage, waste management and remediation activities, Construction;

All variables of ad-hoc module "Self-employment", specified in Commission  Implementing  Regulation  (EU)  2016/8  of 5  January  2016, were covered.

The sample used for the Labour force survey is a two-stage stratified cluster sample which includes quarterly about 19.6 thousand households (representing about 0.65% sampling rate).
The ad-hoc module on self-employment 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 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 results from the ad-hoc module "Self-employment" were presented on 20 June 2018.
 

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