How many boroughs and census areas does Alaska have?

Alaska is organized into 30 county-equivalents: organized boroughs plus census areas. Unlike most states, large portions of Alaska's land lie within the Unorganized Borough and have no county-level government — the census areas are statistical regions used for the decennial count, not administrative jurisdictions.

The largest borough or census area by land area is Yukon-Koyukuk Census Area at 145,768 square miles, home to 5,028 residents. The most populous is Anchorage Municipality with 287,155 residents — a density of 168 people per square mile. At the other end of the scale, Yakutat City and Borough has 672 residents.

Alaska’s capital is Juneau, while the largest city is Anchorage.
