Notes

Alaskan boroughs and census areas Unlike most states, Alaska is divided into boroughs and census areas that serve as county-equivalents for the Census Bureau. If included with the remainder of the counties and county-equivalent areas in the United States, Alaska's boroughs and census areas would occupy the largest 11. Below is a list of these boroughs and census areas that would rank in the top 100 if included in the above list.

The Unorganized Borough, in which all of the census areas are located, is not considered a county-equivalent area and is not included in this list. With an area of , it would easily top the list, outranking every state in the country (except Alaska).

The rankings in the below list reflect the rank each borough or census area would have if included with all counties and county-equivalent areas in the United States (up to #11).
