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).
