KILM 5. Employment by occupation

The indicator for employment by occupation comprises statistics on jobs classified according to major groups as defined in one or more versions of the International Standard Classification of Occupations (ISCO). The most recent version of the International Standard of Occupation, ISCO-08, distinguishes 10 major groups: (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 trade workers; (8) Plant and machine operators and assemblers; (9) Elementary occupations; and (10) Armed forces occupations. Since 2008 countries have progressively adapted their national systems to permit them to report data according to ISCO-08. Data for earlier years, and for countries that have not yet adapted their national systems, are classified according to earlier versions of the classification: ISCO88 and ISCO-68 (see box 5a for the occupational groups covered by these two classification standards).
