A statistical business register (SBR) plays a central part in a system of official economic statistics at a national statistics office. [1]
In comparison, a company register has different purposes: protection, accountability, and control of legal entities.
Countries use whatever data sources they seem relevant: e.g. they often integrate a company register in one form or another.
In EU a corresponding regulation defines register contents:
United Nations Economic Commission for Europe provides Guidelines on Statistical Business Registers which describes the roles of the statistical business register. [2]
European Commission provides a legal framework for business registers for statistical purposes. [3]
