Herfindahl Indexes, Canada, 1999-2002 [Excel]

Concentration statistics summarize the size distribution of units within an industry. Numerous measures have been used for various purposes. These tables present data for the two most common: concentration ratios (CR) and Herfindahl indexes (HI). The CR and HI emphasize different aspects of the size distribution. The CR measures the importance of the largest enterprises directly while the Herfindahl index takes the entire size distribution of enterprises into account. These statistics are classified by the North American Industry Classification System (NAICS). The information source was the Annual Survey of Manufactures.
