Updating the international standard classification of occupations isco 08

Each ESCO occupation is therefore mapped to only one ISCO unit group.It follows from this structure, that ESCO occupation concepts can be equal to or narrower than ISCO unit groups, but not broader.It belongs to the international family of economic and social classifications.ISCO is a tool for organizing jobs into a clearly defined set of groups according to the tasks and duties undertaken in the job.The International Standard Classification of Occupations (ISCO) is a four-level classification of occupation groups managed by the International Labour Organisation (ILO).Its structure follows a grouping by education level.Its most recent version, ISCO-08, was adopted in 2008 and is preceded by three other versions (ISCO-58, ISCO-68 and ISCO-88).This classification will be used from 2011 onward to code occupations in the surveys conducted by Statistics Belgium.

ISCO-08 provides the top four levels for the occupations pillar. This drawing illustrates the role of ISCO 08 in the hierarchical structure of the ESCO occupations pillar: Since ISCO is a statistical classification, its occupation groups do not overlap.

The ISCO-08 revision is expected to be the standard for labour information worldwide in the coming decade, for instance as applied to incoming data from the 2010 Global Round of National Population Censuses.

Each major group is further organized into sub-major, minor and unit (not shown) groups.

The third version, ISCO-88, was adopted by the Fourteenth ICLS in 1987.

Many current national occupational classifications are based on one of these three ISCO versions.
