Classifications are essential for the production, the compilation and the dissemination of statistics. Therefore, INSEE uses a range of national and international classifications.
The French classification of activities, revision 2 (NAF rev. 2, 2008) is the national statistical classification of economic activities in force since the 1st of January 2008. It has replaced the previous classification NAF rev. 1 dating back to 2003.
The French classification of products, revision 2 (CPF rev. 2, 2008) is the national and central statistical classification of products in use since the 1st of January 2008. It has replaced the previous classification CPF rev. 1 dating back to 2003.
The aggregated classification - NA, 2008 replaces the summary economic classification (NES) which was associated to NAF rev. 1. Seven levels of specific groupings of NAF Rev. 2 items have been developed for the purpose of dissemination and economic studies while fully nested in the NAF hierarchy and allowing international comparisons.

Since enforcement of NAF Rev. 2, it has been replaced by a set of 7 specific aggregated levels.
