What this overview covers
This page is a neutral overview of the main official classifications used to describe occupations and industries. It explains how occupational and industry classifications differ and complement each other, so readers can find the right framework.
Occupational classifications such as ISCO group jobs by the tasks involved, while industry classifications such as NACE group businesses by economic activity. Each is maintained by an official body that publishes the authoritative definitions.
What the classifications organise
- Occupational classifications (such as ISCO) group jobs by tasks and duties.
- Industry classifications (such as NACE) group businesses by economic activity.
- Each provides a structured hierarchy from broad to detailed categories.
- Together they give a common language for occupations and sectors.
- Each is maintained by an official body that publishes its definitions.
How employers use classifications
- To describe roles and sectors with recognised, consistent frameworks.
- To map internal job titles and activities to standard categories.
- To support clearer workforce planning and reporting.
- As neutral references when comparing roles or sectors across borders.
How candidates use classifications
- To understand how an occupation or sector is categorised.
- To relate a job title to a recognised occupational group.
- To compare roles and industries using consistent frameworks.
- As neutral references when interpreting descriptions.
Confirm details with the official sources
