Cross-domain evidence graph

Observatory atlas

Follow documented connections between markets, firms, places, publications, and sources. A connection shows a recorded relationship, not that two measures describe the same market.

The peer-reviewed article studies changes in U.S. industry concentration since the late 1990s. It motivates longitudinal scrutiny of industry structure but supplies none of this indicator's 2022 Economic Census rows. Boundary: The paper's firm universe, measures, time window, and research design differ from the current Census industry-HHI contract. Its results are not joined to, pooled with, or used to validate these observations.
