This page lists the classifications used when collecting statistical data for the Workers’ Compensation Center’s (TVK) occupational accidents and occupational diseases register. The classifications are also used in statistics published on the TVK website and in the statistics app.

Classification of occupations

For the purposes of preventing occupational accidents and implementing and developing the Workers’ Compensation Act, TVK maintains a register of claim events and statutory insurance policies, policyholders and paid claims (register of occupational accidents and occupational diseases). In the register, the insured employees’ line of work is classified according to Statistics Finland’s classification of occupations TK 2010. Occupation refers to work which a person performs in an employment relationship as an employee or in self-employment. 

The current classification of occupations was introduced between 2015-2016. As the current and previous classifications of occupations differ in their structure, the revised classification results in an interruption in the occupation-specific time series in occupational accident and occupational disease statistics.

Similarly, Statistics Finland’s classification of occupations TK 2010 is used when reporting wages and salaries to the Incomes Register.

Risk classification

The Workers' Compensation Center maintains a risk classification system describing accident and occupational disease risks, based on the data concerning the industry or work provided in the occupational accident and disease register. (Workers’ Compensation Act section 17)

TVK has also introduced a three-tier risk classification system for occupational classes to assist the selection of an occupational class in the Incomes Register, in situations where the insured works equal hours in two occupations. The risk categories are low risk, medium risk and high risk.

Principal categories of occupations (TK 2010)

1= Managers
2= Professionals
3= Technicians and associate professionals
4= Clerical support workers
5= Service and sales workers
6= Skilled agricultural, forestry and fishery workers
7= Craft and related trades workers
8= Plant and machine operators and assemblers
9= Elementary occupations
0= Armed forces

ESAW variables

Statistics by TVK use variables defined in the European Statistics on Accidents at Work (ESAW) to describe the circumstances of occurrence of occupational accidents. Classification under the ESAW system began in Finland in 2003.

There are eight ESAW variables that describe the causes and circumstances of accidents at work:

  • working process,
  • specific physical activity,
  • deviation,
  • contact and mode of injury,
  • material agent associated with the mode of injury,
  • workstation (until 2015),
  • working environment (from 2016),
  • type of injury, and
  • part of body injured.

Of this classification of variables, the version used in Finland is abridged in certain respects. The abridged classification is described in the joint publication Classification of Accidents at Work (Työtapaturmien luokittelu) by the Ministry of Social Affairs and Health and TVK. [linkki dokumenttiin]

The variables “circumstances of the claim event”, “claim event according to the claim decision” and “mental shock reaction” are not based on ESAW methodology but nationally collected statistics.

Severity rating

Severity is determined based on the duration of the employee’s disability. Duration is calculated by the number of calendar days, including Sundays and holidays, which the injured person is fully or partially disabled. The date of the injury is not counted when calculating the duration of disability.
