Statistics for related categories can be grouped together or aggregated in order to provide a broader picture. Thus, an aggregate is the combination of related categories, usually within a common branch of a hierarchy, to provide information at a broader level to that at which detailed observations are taken. For example, EU-aggregated data would refer to evidence presented for the EU as a whole, and not for specific countries.
