The European Socio-economic Classification (ESeC) is an occupationally based classification but has rules to provide coverage of the whole adult population. The information required to create ESeC is:

  • occupation coded to the minor groups (i.e. 3-digit groups) of the International Standard Classification of Occupations 1988 (ISCO88 (COM))
  • details of employment status, i.e. whether an employer, self-employed or employee;
  • number of employees at the workplace
  • whether a worker is a supervisor.
