Terminology

The term county equivalents includes in addition three types of units outside that definition:

  1. Alaska census areas: areas, defined by the United States Census Bureau for statistical purposes, that have no corresponding governmental unit. (In the late 20th century, the totality of these census areas was the "unorganized borough.") Most of the land area of Alaska is divided into these 11 census areas.
  2. Independent cities: These are cities that legally belong to no county in a state. As of 2004, there are 43 such cities in the United States:
  3. The District of Columbia, a federal district under the absolute jurisdiction of the US Congress, which has for the last several decades allowed the District a limited home rule.

Including these jurisdictions, the United States has 3,141 counties and county equivalents.

City-county exceptions

As noted, the territory of most counties includes that of municipalities, within and smaller than the respective counties. However, there are three kinds of exceptions to this arrangement:

  1. By a series of annexations or other mergers, a city government may come to have exactly the same territory as the county that contains it, even though they remain separate governments. This is nearly the case in Jacksonville, Florida, which has incorporated all of Duval County except for four smaller suburban cities.
  2. Several cities and counties around the country have unified their governments; these consolidated city-county governments are considered both a city and a county under state law. Prominent examples include Denver, Colorado, Honolulu, Hawaii, Louisville, Kentucky, Nashville, Tennessee, Philadelphia, Pennsylvania, and San Francisco, California.
    • The area now forming the five boroughs of New York City consisted, into the late 19th century, of three typical counties and parts of two others, each containing at least one city or town. These are still counties in name and in state law; nevertheless, since 1898 they have been entirely contained within the boundaries of the city, and following the creation of Bronx County in 1914, each borough now corresponds exactly to one county.
  3. In several states, (including Colorado, Georgia, Michigan, Minnesota, Ohio, Tennessee, Texas, and Utah) a city may annex land within an adjacent county. That land is then subject to city government, but the respective counties continue to provide county-specific services and residents vote for county officials in the respective counties.
  4. In Michigan, the city may petition to change the county boundaries to accord with the city boundaries. Historically, however, this has rarely been exercised. There are many cities that span county boundaries in Michigan.

Statistics

Main article: County statistics of the United States

By area, the largest county in the United States is North Slope Borough, Alaska at 94,763 square miles (245,435 km²) and the smallest county in the United States is Kalawao County, Hawaii at 13 square miles (34 km²).

However, when county equivalents are included, both lose their status. The largest county equivalent by area is Yukon-Koyukuk Census Area, Alaska at 147,843 square miles (382,912 km²) and the smallest is the independent city of Falls Church, Virginia at 2.0 square miles (5 km²).

The most populous county (or county equivalent) is Los Angeles County, California with 10,226,506 people as of 2005, and the least populous county is Loving County, Texas with 67 people as of 2000.

Scope of power

It has been proposed that County seat be merged and redirected into this article.

This request may be discussed on the article's talk page.

The power of county governments varies widely from state to state, as does the relationship between counties and incorporated cities.
