Statistical concepts and definitions

Employees are all persons who have a labour contract (fixed or permanent; full-time or part-time) with their employer by virtue of the Labour Code or the Civil Servants Act and who receive remuneration in cash or in kind for certain quality and quantity of work done.

The average annual number of employees is the arithmetic mean value of the average monthly number of employees. The average monthly number of employees is the arithmetic mean value of the daily number of employees (sum of the daily number of employees divided by the number of days for the reference month). Part-time employees are converted into full-time equivalents.

Gross annual wages and salaries are the remunerations paid regularly to the employees by the employers before the deduction of any tax and social security contributions payable by the employees and withheld by the employers. Gross wages and salaries comprise of: basic wages and salaries for time worked or work done; payments for statutory, contractual or voluntary leave; payments for overtime, shift work, extreme working conditions, length of service; monthly, quarterly and annual bonuses. The average annual wages and salaries are calculated through dividing the total amount of wages and salaries costs accrued during the reference year by the average annual number of employees under labour contract excluding those on maternity leave.

Inflows and outflows - number of employees hired and dismissed during the reference year.

Total Labour Costs includes wages and salaries paid by the employer in cash or in kind, employers' actual and imputed social contribution plus taxes regarded as labour costs.

Accuracy and reliability
Overall accuracy

The overall accuracy of the survey results depends of:

· Survey tools. The statistical form for the survey is available in electronic and paper format. In 2008 the survey become part from Information system Business Statistics, which is on-line based allowing 24 hours data collection and incorporates logical and arithmetic controls visible immediately during the data entry;

· Methods for errors identification and correction. The data processing goes through three main stages of validation: 1) data are validated while entered to control the plausibility of the inserted values and item non-response; 2) at regional level, the Regional Statistical Offices of NSI perform post-validation incl. checks for coverage, extreme and missing values; 3) at national level, the Head Office of NSI performs additional validation as well for coverage and completeness. Comparability is made with administrative and other sources.

Sampling error

Not applicable - the survey is exhaustive.

Non-sampling error
Timeliness and punctuality

The survey results are published 11 months after the reference period.


The survey results are presented at the actual date set in the National Statistical Institute Release Calendar.

Preliminary annual estimates for number of employees and average wages and salaries are published as well from the quarterly sample survey on Number of employees, time worked, wages and salaries and other labour costs.

Coherence and comparability
Comparability - geographical

The national and regional statistical data on employees and wages and salaries are in compliance with the acting Classification of territorial units for statistical purposes in Bulgaria (NUTS).

Comparability - over time

The comparability over time is disturbed by the changes of the Classification of Economic Activities. Up to 2007 NACE.BG 2003 was in force, since 2008 NACE.BG 2008 was implemented, which resulted in break of the time series for number of employees and wages and salaries.

Coherence - cross domain

All indicators are internal coherent.

Coherence - internal

Coherence of the employment data between the Labour Force Survey (LFS) and the survey on Number of employees, wages and salaries and other labour costs

The main difference between the both sources is due to the fact that the survey on Number of employees, wages and salaries and other labour costs collects information on the persons which have an employment contract according to the Labour Code or Civil Servants Act, while Labour Force Survey covers employees working by other type of contract or without any contract, as well the self-employed (working proprietors, own account works and unpaid family workers). LFS includes armed forces, but excludes persons on leave for raising a child up to two years of age.

Methodological differences such as: sampling unit, reference period, methods of data classification by economic activity, regional distribution (working place/ residence) etc. are potential reason for data discrepancies as well.

Cost and burden
