Data description

Quarterly data from the Labour force survey

The Labour force survey (LFS) 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 on the main characteristics of employed, unemployed and persons out of labour force in the Republic of Bulgaria.

Classification system

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

  • International Standard Classification of Education, 1997 version (ISCED 1997) - until the end of 2013;
  • International Standard Classification of Education, 2011 version (ISCED 2011) - since the beginning of 2014;
  • 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 the end of 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 the beginning of 2011;
  •  International classification of professional status - ICSE-93;
  • Classification of Territorial Units for Statistical Purposes in Bulgaria - NUTS.
Sector coverage

All persons aged 15 years and over living in the selected non-institutional households are covered.

Statistical concepts and definitions

The Labour force survey provides estimates for 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 definition of unemployment is according to Commission Regulations No1897/2000.

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.

Unemployed are persons aged 15 to 74 who:

  •  did not work at all during the reference period;
  •  were actively seeking work within the preceding four weeks, including the reference one or have found a new job or business that is expected to start within 3 months following the reference period;
  •  were available to start working within two weeks following the reference period.

Economically active population (labour force) comprises all employed and unemployed persons.

Activity rate - ratio between the economically active population and the total population of the same age group.

Employment rate - ratio between the employed population and the total population of the same age group.

Unemployment rate - ratio between the unemployed persons and the economically active population.

Duration of unemployment is the duration of the search for employment or the length of the period since leaving last job; whichever period is shorter.

Long-term unemployed are persons who have been unemployed for one or more years.

Long-term unemployment rate - ratio between the long-term unemployed persons and the economically active population.

Persons not in the labour force (inactive population) are persons aged 15 and over who were neither employed, nor unemployed during the reference period. All persons on leave for taking care of children until 2 years of age are included.

Discouraged persons are persons not in the labour force who want to work but they do not actively look for a job, because they do not believe they will find one.

Working time. Distinction between full-time and part-time work is made according to the subjective declaration of the respondents.

The number of actual working hours per week refers to the main job, incl. paid or unpaid overtime.

Professional status. According to the 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 NACE.BG 2008. 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;
  • The Service sector includes all other economic activities.

Occupations. Occupation is defined by the type of work that the person carries out on the main job during the reference week. Employed persons are classified by occupation according to the National Classification of Occupations and Duties-2011 (1st digit - occupational class), comparable to the International Standard Classification of Occupations - ISCO-08.

Accuracy and reliability
Overall accuracy

The sample used for the Labour force survey is a two-stage stratified cluster sample which includes about 19.6 thousand households (about 0.65% sampling rate). 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.

Sampling error

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.

 


Non-sampling error
Timeliness and punctuality
Timeliness

The main LFS results are released 45 calendar days after the end of the reference quarter.

Punctuality

The LFS results are released strictly to the Release Calendar.

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

Since the beginning of 2003 a quarterly continuous Labour force survey which provides quarterly and annual estimates is implemented. From the same year the harmonised definition of unemployment in accordance with Commission Regulation No 1897/2000 has been applied.

In the first quarter of 2012 a new weighting procedure was introduced in the Labour force survey which should be taken into account in use of LFS data. The main differences were the following:

  • the number of age groups at national level for which the consistence between LFS estimates and current population estimates is achieved  increased (from 4 to 14);
  • population data used in LFS weighting procedure exclude population living in institutional households (which are not covered by the survey).

The discrepancy between current population estimates (used for initial quarterly LFS estimates in 2010 and 2011) and the data from the Population Census as of 1 February 2011 has also impact over the comparability of LFS data. Due to availability of new population estimates based on 2011 Population Census and changes in the weighting procedure revised LFS estimates for 2010 and 2011 are produced and published at the NSI website.

In consequence the revised data for 2010 are not fully comparable with those for previous years.

 

Coherence - cross domain

 Coherence with population data

The LFS uses the latest available population estimates (by age, place of residence, age group and districts) to gross up sample results. Since 2012 population data used for LFS estimates excluded persons living in collective households (which are out of scope of the survey).

 Coherence with employment estimates in National Accounts

 National Accounts use different data sources which are combined to obtain the best comprehensive and consistent estimate. In results National Accounts data could differ from the results of each source. For Bulgaria the main difference between LFS and NA refers to Agricultural employment. In the estimation of self-employment in agriculture NA use data based on Agricultural Census and sample surveys, carried out by Ministry of Agriculture and Food.

NA employment data are based on domestic concept (employment in resident production units irrespective of the place of residence of the employee) while LFS gives information on the national concept (i.e. resident employed).

LFS does not cover persons living in collective households and persons on leave for taking care of a child until 2 years of age, which are included in NA employment estimates.

 Coherence with Annual and Quarterly Surveys on employees, hours worked, wages and salaries and other expenditures paid by the employer

 The main methodological difference between the two surveys is the coverage of employed persons. The surveys on employee, hours worked, wages and salaries and other expenditures provides data on persons who work under employment contract according to the Labour Code or the State Officials Act, while the labour force survey covers also persons employed by other type of contract or without formal contract and self employed persons (employers, own account workers and unpaid family workers). The published data on employees by labour contract do not include defence and public security activities.

The existed differences in terms of survey units, reference periods, modes of classifying by economic activities (register/description given by the respondents), principles of territorial treatment (by place of work/by place of living) also influenced on the comparability of results from the surveys.

 Coherence with registered unemployment data

The main methodological differences between the LFS data on unemployment and data on registered unemployment provided by National Employment Agency are the following:

  •  According to the International Labour Organisation (ILO) definition applied in Labour force survey unemployed are considered not only and not all persons, registered in employment offices, but also those who are looking for job using other active methods: by private employment agencies, direct application to employers, assistance from friends or relatives, placing, answering or studying job advertisements in newspapers, magazines. The registration itself is not regarded as active method but the contact with an employment agency with a purpose to find job.
  • The age at which persons could be considered as unemployed is 15 - 74 years for Labour force survey and 16 - 64 years for registered unemployed. In contrast to registered unemployed students and pensioners are considered as unemployed in LFS if are actively looking and available for work.
  • The data on economically active population used as denominator for the calculation of unemployment rate is different - in LFS economically active population consists of employed and unemployed which number is estimated through the same survey while for calculation of registered unemployment rate Population Census data for economically active population is used.
Coherence - internal

Some of the totals (rows and columns) in tables are not equal to the sum of the components because of the rounding of figures.

Cost and burden

The average duration of LFS interview is about 15 minutes per person. The individual duration of an interview depends on the labour status of person and survey wave.

Data revision
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

Due to availability of new population estimates based on 2011 Population Census and changes in LFS weighting procedure revised quarterly LFS data for 2010 and 2011 are produced and published at the NSI website.


Statistical processing
Source data

Source of data is Labour force survey, carried out over a sample of 19.6 thousand households.

Frequency of data collection

Data collection

Data are collected through paper questionnaire and personal interview with persons (aged 15 or over) from the selected households.

Data validation

Plausibility checks are performed during the data entry. Additional consistency checks are carried out before publishing of data.  

Data compilation

The filled in 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.

Economically active population (labour force) comprises all employed and unemployed persons.

Activity rate - ratio between the economically active population and the total population of the same age group.

Employment rate - ratio between the employed population and the total population of the same age group.

Unemployment rate - ratio between the unemployed persons and the economically active population.

Duration of unemployment is the duration of the search for employment or the length of the period since leaving last job; whichever period is shorter.

Long-term unemployed are persons who have been unemployed for one or more years.

Long-term unemployment rate - ratio between the long-term unemployed persons and the economically active population.

Persons not in the labour force (inactive population) are persons aged 15 and over who were neither employed, nor unemployed during the reference period. All persons on leave for taking care of children until 2 years of age are included.

Discouraged persons are persons not in the labour force who want to work but they do not actively look for a job, because they do not believe they will find one.

Working time. Distinction between full-time and part-time work is made according to the subjective declaration of the respondents.

The number of actual working hours per week refers to the main job, incl. paid or unpaid overtime.

Professional status. According to the 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;

Source of data is Labour force survey, carried out over a sample of 19.6 thousand households.

Frequency of data collection

Quarterly

Data collection

Data are collected through paper questionnaire and personal interview with persons (aged 15 or over) from the selected households.

Data validation

Plausibility checks are performed during the data entry. Additional consistency checks are carried out before publishing of data.  

Data compilation

The filled in 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.

Accuracy and reliability
Overall accuracy

The sample used for the Labour force survey is a two-stage stratified cluster sample which includes about 19.6 thousand households (about 0.65% sampling rate). 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.

Sampling error

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.

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

Due to availability of new population estimates based on 2011 Population Census and changes in LFS weighting procedure revised quarterly LFS data for 2010 and 2011 are produced and published at the NSI website.

Coherence and comparability

Comparability - geographical

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

Asymmetry for mirror flows statistics - coefficient

Not applicable.

Comparability - over time

Since the beginning of 2003 a quarterly continuous Labour force survey which provides quarterly and annual estimates is implemented. From the same year the harmonised definition of unemployment in accordance with Commission Regulation No 1897/2000 has been applied.

In the first quarter of 2012 a new weighting procedure was introduced in the Labour force survey which should be taken into account in use of LFS data. The main differences were the following:

  • the number of age groups at national level for which the consistence between LFS estimates and current population estimates is achieved  increased (from 4 to 14);
  • population data used in LFS weighting procedure exclude population living in institutional households (which are not covered by the survey).

The discrepancy between current population estimates (used for initial quarterly LFS estimates in 2010 and 2011) and the data from the Population Census as of 1 February 2011 has also impact over the comparability of LFS data. Due to availability of new population estimates based on 2011 Population Census and changes in the weighting procedure revised LFS estimates for 2010 and 2011 are produced and published at the NSI website.

In consequence the revised data for 2010 are not fully comparable with those for previous years.

Coherence - cross domain

 Coherence with population data

The LFS uses the latest available population estimates (by age, place of residence, age group and districts) to gross up sample results. Since 2012 population data used for LFS estimates excluded persons living in collective households (which are out of scope of the survey).

 Coherence with employment estimates in National Accounts

 National Accounts use different data sources which are combined to obtain the best comprehensive and consistent estimate. In results National Accounts data could differ from the results of each source. For Bulgaria the main difference between LFS and NA refers to Agricultural employment. In the estimation of self-employment in agriculture NA use data based on Agricultural Census and sample surveys, carried out by Ministry of Agriculture and Food.

NA employment data are based on domestic concept (employment in resident production units irrespective of the place of residence of the employee) while LFS gives information on the national concept (i.e. resident employed).

LFS does not cover persons living in collective households and persons on leave for taking care of a child until 2 years of age, which are included in NA employment estimates.

 Coherence with Annual and Quarterly Surveys on employees, hours worked, wages and salaries and other expenditures paid by the employer

 The main methodological difference between the two surveys is the coverage of employed persons. The surveys on employee, hours worked, wages and salaries and other expenditures provides data on persons who work under employment contract according to the Labour Code or the State Officials Act, while the labour force survey covers also persons employed by other type of contract or without formal contract and self employed persons (employers, own account workers and unpaid family workers). The published data on employees by labour contract do not include defence and public security activities.

The existed differences in terms of survey units, reference periods, modes of classifying by economic activities (register/description given by the respondents), principles of territorial treatment (by place of work/by place of living) also influenced on the comparability of results from the surveys.

 Coherence with registered unemployment data

The main methodological differences between the LFS data on unemployment and data on registered unemployment provided by National Employment Agency are the following:

  •  According to the International Labour Organisation (ILO) definition applied in Labour force survey unemployed are considered not only and not all persons, registered in employment offices, but also those who are looking for job using other active methods: by private employment agencies, direct application to employers, assistance from friends or relatives, placing, answering or studying job advertisements in newspapers, magazines. The registration itself is not regarded as active method but the contact with an employment agency with a purpose to find job.
  • The age at which persons could be considered as unemployed is 15 - 74 years for Labour force survey and 16 - 64 years for registered unemployed. In contrast to registered unemployed students and pensioners are considered as unemployed in LFS if are actively looking and available for work.
  • The data on economically active population used as denominator for the calculation of unemployment rate is different - in LFS economically active population consists of employed and unemployed which number is estimated through the same survey while for calculation of registered unemployment rate Population Census data for economically active population is used.
Coherence - sub annual and annual statistics

The yearly LFS data are calculatd as average of the four quarters of the respective year.

Coherence - National Accounts

 Coherence with employment estimates in National Accounts

 National Accounts use different data sources which are combined to obtain the best comprehensive and consistent estimate. In results National Accounts data could differ from the results of each source. For Bulgaria the main difference between LFS and NA refers to Agricultural employment. In the estimation of self-employment in agriculture NA use data based on Agricultural Census and sample surveys, carried out by Ministry of Agriculture and Food.

NA employment data are based on domestic concept (employment in resident production units irrespective of the place of residence of the employee) while LFS gives information on the national concept (i.e. resident employed).

LFS does not cover persons living in collective households and persons on leave for taking care of a child until 2 years of age, which are included in NA employment estimates.
