Methodology of employer business demography statistics

Data sources

The employer business demography data are compiled on the basis of the business register and additional to that with administrative sources of Statistics Austria’s business register. The following data sources being used:

  • Basic tax data and turnover tax data taken from turnover tax returns and advance turnover tax returns submitted to the tax authorities and income tax data
  • Employer and employee data from the Main Association of Austrian Social Insurance Institutions

The year of birth was defined as the year in which the enterprise first employed at least one person (this threshold corresponds to the threshold for inclusion in the business register). On the other hand, the year of death was defined as the year in which the enterprise last had employees regardless of whether the enterprise continued its activity (without employees) or not.

The two databases were matched using record linkage. An attempt was then made to exclude false births by comparing pairs of names, principal economic activities and addresses. In addition, a sample was taken of births with fewer than 20 employed persons, which was checked manually using Statistics Austria's business register; the proportion of real births was extrapolated to the total population.

Survey unit and definitions

The survey unit used in employer business demography is the employer enterprise. An employer enterprise is defined as an enterprise with at least one employee and is a legal (organizational) unit that produces goods or services and has a certain degree of autonomy in decision-making, especially for the allocation of its current resources. The enterprise may carry out one or more activities at one or more locations (local units).


An employer enterprise is considered to be economically active if it employed persons at any point in time between 1 January and 31 December in a reporting year, irrespective of whether the enterprise was active for the entire year or only parts thereof.

Birth of an employer enterprise

Two types of becoming an employer (“employer enterprise births”) can be distinguished: On the one hand, the birth of an enterprise that had at the time of its creation at least 1 employee. And on the other hand, “entry by growth”, i.e. an enterprise that was already active without employees and reaches the threshold of 1 employee in the reference year. The condition is that the enterprise in two years, preceding the reference year, employed no employees (to exclude reactivation). The growth should not be due to a takeover of a company with employees.

Death of an employer enterprise

Accordingly, two types of employer enterprise deaths can be distinguished: On the one hand, the death of an employer enterprise that had at the time of its cessation at least 1 employee. And on the other hand, “exit by decline”, i.e. an active enterprise that last had employees during the reference year (irrespective whether it continued its activity without employees) and that for two years (to exclude reactivation).

Survival of an employer enterprise

An employer enterprise is considered to have survived if it is economically active (in terms of employment) in its year of birth and in subsequent years. An employer enterprise is also considered to have survived if a legal unit of the enterprise ceases its activity but the production factors are taken over by a new legal unit set up specifically for this purpose.

Employed persons

The number of employed persons corresponds to the total number of persons working for the observation unit (self-employed persons and employees).
