⁸ Gastil's regions are grouped as Northeast (New England, Pennsylvania, New York Metropolitan); Middle West (Upper Midwest, Central Midwest); South (South); West (Interior Southwest, Pacific Southwest, Pacific Northwest, Mormon, Rocky Mountain).

⁹ Trans-regional athletic conferences according to census region boundaries are: Northeast-South (Atlantic Ten, Big East, East Coast, ECAC-Metro, Middle Atlantic); Middle West-South (College Athletic, Metro, Midwestern City, Missouri Valley, Ohio Valley); West-South-Middle West (Big Eight); West-South (Western). Use of Gastil's boundaries adds the Central States and Mid-Continent conferences to those spanning Middle West-South and eliminates the Western Conference as a trans-regional league.

¹¹ Using census regions, the states participating only in regionally isolated leagues are as follows: Northeast (Maine, New Hampshire, Vermont); South (North Carolina, Georgia, Alabama, Arkansas, Louisiana); Middle West (Minnesota, Wisconsin); West (Washington, Oregon, Idaho, Montana, Nevada, Arizona). Use of Gastil's regions requires no changes for the Northeast and South; elimination of Wisconsin for the Middle West; and addition of Wyoming, Utah, New Mexico, California, and Hawaii for the West.
