Japan Standard Occupational Classification (Rev. 5th, December 2009)
Points of Concern in Applying the Japan Standard Occupational Classification
Points of Concern in Applying the Japan Standard Occupational Classification (:26KB)
This Occupational Classification applies to official statistics produced by statistical surveys conducted on or after the date of executing this public notification.
As for official statistics produced by using any method other than a statistical survey, this Classification applies to those to be produced on or after said date.
However, if there is any unavoidable reason for not being able to apply this Occupational Classification, another classification may be used.
In that case, the classification actually used must be specified.
Since the Occupational Classification is independent from the industrial classification of establishments, forms of employment of individuals, and the duration or continuity of work, it should be used after designating the target duration and timing, as well as the continuity of work for each statistical survey or other related activity.
In applying the Occupational Classification, it is possible in accordance with the purpose of producing the statistics to use only part of the classifications in the classification table, as well as to set up a Sub-Unit Group and consolidate or split classifications within a certain scope as shown below.
- (1) A Sub-Unit Group may be set up under a Unit Group. In this case, however, it is necessary to ensure consistency between the Unit Group and Sub-Unit Group.
- (2) It is possible to split a Minor Group into units of Unit Groups included in the Minor Group to set up a new Minor Group within the Major Group to which the original Minor Group belonged, and set up a new Minor Group by consolidating multiple Minor Groups within one and the same Major Group.
- (3) It is possible to split a Unit Group into a given unit to set up a new Unit Group within the Minor Group to which the original Unit Group belonged, and set up a new Unit Group by consolidating plural Unit Groups within one and same Minor Group.
- (4) In case of splitting or consolidating groups in accordance with (2) or (3) above, consolidating a group that was newly set up by splitting with another group or splitting a group that was newly set up through consolidation is likely to impair the systematization of the Occupational Classification.
Therefore, if this is to be done, the Occupational Classification shall be deemed inapplicable.
