This paper presents new evidence on industry concentration at both the country and the world-region levels. It calculates country-level industry concentration measures from the novel data representative of the entire firm population in 12 European countries, and it develops a methodology for calculating industry concentration at the supranational level using detailed cross-country data on subsidiaries of business groups. This paper documents that industry concentration has increased not only in North America but also in Europe since 2000, albeit to a lesser extent.
