NACE Classification

INTRODUCTION
English translation pending.
CORE DEFINITION
NACE is the statistical classification of economic activities used in the European Union, a hierarchical coding system that assigns each activity a code based on what the unit actually does. The core proposition is that cross-country comparison is impossible without a shared classification, so the classification itself is the infrastructure that makes the data comparable. The key qualification is that assignment requires judgment: units performing several activities must be classified by their principal activity, and the codes are revised periodically.
SCAFFOLDING EFFECT
Reduce cognitive load
- Principal activity rule: classify a unit by what it mainly does rather than by everything it does. - Level choice: select the classification depth that matches the comparison you need. - Version check: confirm which revision of the classification the data was coded under.
Anchor fast decisions
A hierarchical code assigns each economic unit to one position in a shared tree, so aggregate statistics built from those codes add up the same way in every country. Because the rule is based on activity rather than on legal form or name, dissimilar organizations doing similar work land in the same category. Comparability therefore comes from the coding discipline rather than from any central harmonization of the underlying firms.
