Day-to-day personal activities are presented in line with the list of activities drawn up by Eurostat, whose maximum level of disaggregation is three digits.

The major groups are a one-digit aggregate, and the basic objective of their design is to help identify output activities at the limits of the central system of national accounts, as well as allowing the production of satellite accounts for the household sector. The flexibility of the classification also allows data to be extended to other types of report or analysis.
