List of boroughs and census areas in Alaska
The U.S. state of Alaska is not divided into counties, like the other 48  states (Louisiana has parishes), but instead is divided into boroughs. Many of the more densely populated parts of the state are in Alaska's 19 organized boroughs, which are somewhat similar to counties in other states. Unlike in the other states, the organized boroughs do not completely cover all of the land in the state. The areas that are not part of any organized borough are called the unorganized borough.
