A NACE special aggregate, as defined in Annex II of Regulation (EU) 2024/1840, refers to a grouping of economic activities that are combined to serve specific analytical or policy purposes, beyond the standard classification levels of the NACE system. These aggregates are constructed by selecting certain NACE codes and combining them to provide insights into specific sectors or themes that are relevant for economic analysis or policy-making. The creation of these aggregates allows for more targeted data analysis and reporting, addressing particular economic sectors or issues that are not easily captured by the conventional classification structure.
