Business demography describes the life cycle of the enterprises, their birth, survival and development until death. More specifically business demography supplies data on number of active enterprises, number of newborn enterprises, proportion of survived enterprises and data on changes in employment figures at specific moment in time.

Number of active enterprises is the number of registered legal entities or individuals who have had turnover or employees in the reference year (t).
Newly born enterprises during the year (t):
- Enterprises that were active in the reference year (t), but were not active in year (t-1) and in year (t-2).
- Or enterprises that have been active in years (t-1) and (t-2), but with zero number of employees. Events such as mergers, dissolution, separation, change of legal form or revival excluded from newborn enterprises.
Dead enterprises during the year (t), are those that were active in the reference year (t), with at least one employee but has not been active in any year (t+1), nor in the year (t+2). Or have been active in years (t+1) and (t+2), but with zero number of employees. Events such as mergers, dissolution, separation, change of legal form or revival excluded from newborn enterprises.
Survived enterprises are newly born enterprises in years (t-1) to (t-5), which are still active in the reference year (t).
Employees are persons who work for an employer (for legal entities registered or individuals) receive payment in the form of salaries and are socially insured on the basis of an employment contract. The employment contract can be for a definite or indefinite period of time, full time or part time.
Number of persons employed is defined as the total number of persons who work in the observed enterprise (for payment or not), as well as persons who work outside, but are paid by it (e.g. sales representatives).
The observed unit is enterprise.

The main information source for Business demography data is the Register of statistical units of the NSI.
The Register of statistical units covers all legal units registered on the territory of Bulgaria and there is not apply any threshold for inclusion in its scope. The register has a history of events and contains enterprise birth and death dates.
The administrative part of the Register of statistical units is updated with information obtained from the Trade Register.
The statistical part of the Register of statistical units are updated based on information received from IS "Business statistics", National Revenue Agency and National Social Security Institute.
|Frequency of data collection|
The administrative part of the Register of statistical units is updated daily with information received from the Trade Register.
The statistical part of the Register of statistical units is updated annually with monthly information on employees obtained from National Social Security Institute.
Annually there is update of the register with data from IS "Business Statistics" and National Revenue Agency.
Business demography data are based on administrative and statistical data sources that are used to update information in the Register of Statistical Units.
Before data on business demography to be provided to Eurostat there is performed validation of all data series in terms of hierarchical, inter-variable plausibility, confidentiality and completeness with EBD tool.
In data compilation process there are used different tools and techniques. Unique IT solutions and tools has been developed, in addition SPSS, Visual Fox Pro and CIF has been used for data checking, verification and secondary confidentiality treatment.
According to Art. 2, Para. 3 of the Law on Statistics, the statistical information are produced in compliance with certain quality criteria, such as relevance, accuracy, timeliness, punctuality, accessibility and clarity, comparability and coherence.
NSI prepares and submits to Eurostat a quality report on business demography data by the end of March of the relevant year.
Regulation (EC) No 295/2008 of the European Parliament and of the Council concerning structural business statistics requires the European Commission (Eurostat) regularly (every three years) to submit a report to the European Parliament and of the Council on the quality of statistics compiled.
The main users of data are:
· Eurostat and other international organizations;
· Public administration;
· Research institutes, universities, economic analysts and students;
· Private non-governmental organizations, agencies, associations, media, etc.
· Regional Statistical Offices/Directorates/Departments of the NSI.
There has been no study on user satisfaction for the provided business demography information. NSI conducts regular User Satisfaction Survey for provided statistical information products and services, the results of which are published on the NSI website at: https://www.nsi.bg/node/11744/
