Relationship to international standards

(e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)JSOC is individually made to reflect the occupational structure in Japan. Therefore, some differences in the coverage of each division may be observed between ISCO and JSOC. For example, “Technical and medical sales professionals”,” Information and communications technology sales professionals” are classified in " 2 - Professionals " in ISCO. They are classified in " D Sales workers " in JSOC.
3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.Administrative and managerial workers are not separated in self-defense officials, police officers, maritime safety officials and firefighters in major group F-Security workers.

(Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)To some extent the data about at level 1 of ISCO are provided by replacing unit groups of “Population Census”.
