The aggregated classification - NA, 2008 replaces the summary economic classification (NES) which was linked to NAF rev. 1. With the 2008 classification review, the NES just disappeared due to its strictly national nature: as NES did not respect the tree structure of ISIC and NACE, it could not be used for international comparisons.
Additional levels of groupings to standard levels of sections (21 items) and divisions (88 items) were nevertheless needed for summarizing data for the purpose of economic analysis or dissemination.
7 aggregated levels, associated to NAF rev. 2, were delineated, their name being " A xx " where xx refers to the number of items of the level.
Both variants, either with A 17 level or A 21 level, are provided in the downloadable files below.
