Geographic contiguity

Last updated

Geographic contiguity is the characteristic in geography of political or geographical land divisions, as a group, not being interrupted by other land or water. Such divisions are referred to as being contiguous. In the United States, for example, the "48 contiguous states" excludes Hawaii and Alaska, which do not share borders with other U.S. states. [1]

Other examples of geographical contiguity might include the "contiguous European Union" excluding member states such as Ireland, Sweden, Finland (between Åland and Turku Archipelago), Malta and Cyprus (these being non-contiguous), or the "contiguous United Kingdom" referring to all parts of the country excepting Northern Ireland (it being geographically non-contiguous).

Two or more contiguous municipalities can be consolidated into one, or one municipality can consist of many noncontiguous elements. For example, the Financially Distressed Municipalities Act allows the commonwealth of Pennsylvania to merge contiguous municipalities to reduce financial distress.

Geographic contiguity is important in biology, especially animal ranges. For a particular species, its habitat may be a 'contiguous range', or it might be broken, requiring periodic, typically seasonal migrations (see: Disjunct distribution). The same concept of contiguous range is true for human transportation studies in an attempt to understand census geography. [2] It also comes into play with electoral geography and politics. [3]

In United States real property and mineral rights law, touching of two tracts at a common corner (as on a checkerboard) is generally considered contiguous. [4]

County Geographical and administrative region in some countries

A county is a geographical region of a country used for administrative or other purposes in certain modern nations. The term is derived from the Old French conté or cunté denoting a jurisdiction under the sovereignty of a count (earl) or a viscount. Literal equivalents in other languages, derived from the equivalent of "count", are now seldom used officially, including comté, contea, contado, comtat, condado, Grafschaft, graafschap, and zhupa in Slavic languages; terms equivalent to English language administrative terms such as municipality, district, circuit and commune/community are now often instead used.

Town Type of settlement

A town is a human settlement. Towns are generally larger than villages and smaller than cities, though the criteria to distinguish between them vary considerably in different parts of the world.

Contiguous United States 48 states of the United States apart from Alaska and Hawaii

The contiguous United States or officially the conterminous United States, also known as the Lower 48, consists of the 48 adjoining U.S. states and the District of Columbia on the continent of North America. The terms exclude the non-contiguous states of Alaska and Hawaii and all other offshore insular areas, such as American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands. These differ from the related term continental United States, which includes Alaska but excludes the Hawaiian Islands and all U.S. territories in the Caribbean and the Pacific.

County (United States) Subdivision used by most states in the United States of America

In the United States, a county is an administrative or political subdivision of a state that consists of a geographic region with specific boundaries and usually some level of governmental authority. The term "county" is used in 48 U.S. states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively.

District Administrative division, in some countries, managed by local government

A district is a type of administrative division that, in some countries, is managed by the local government. Across the world, areas known as "districts" vary greatly in size, spanning regions or counties, several municipalities, subdivisions of municipalities, school district, or political district.

Unincorporated area Region of land not governed by own local government

An unincorporated area is a region not governed by a local municipal corporation. Similarly, an unincorporated community is a settlement not governed by its own local municipal corporation, but is administered as part of larger administrative divisions, such as a township, parish, borough, county, city, canton, state, province, or country. Occasionally, municipalities dissolve or disincorporate, which may happen if they become fiscally insolvent, and services become the responsibility of a higher administration. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. Most other countries of the world have either no unincorporated areas at all, or these are very rare; typically remote, outlying, sparsely populated, or uninhabited areas.

A township in some states of the United States is a small geographic area.

An electoral district, also known as an election district, legislative district, voting district, constituency, riding, ward, division, (election) precinct, electoral area, circumscription, or electorate, is a subdivision of a larger state created to provide its population with representation in the larger state's legislative body. That body, or the state's constitution or a body established for that purpose, determines each district's boundaries and whether each will be represented by a single member or multiple members. Generally, only voters (constituents) who reside within the district are permitted to vote in an election held there. District representatives may be elected by a first-past-the-post system, a proportional representative system, or another voting method. They may be selected by a direct election under universal suffrage, an indirect election, or another form of suffrage.

Local government in the United States refers to governmental jurisdictions below the level of the state. Most states and territories have at least two tiers of local government: counties and municipalities. Louisiana uses the term parish and Alaska uses the term borough for what the U.S. Census Bureau terms county equivalents in those states. Civil townships or towns are used as subdivisions of a county in 20 states, mostly in the Northeast and Midwest.

Congressional districts, also known as electoral districts, legislative districts, wards, and electorates in other nations, are divisions of a larger administrative region that represent the population of a region in the larger congressional body. Notably, in Australia, electoral districts are referred to as "electorates" or "seats"; in Canada, these are called "constituencies", or, more informally, "ridings". Countries with congressional districts include the United States, the Philippines, and Japan.

Apportionment is the process by which seats in a legislative body are distributed among administrative divisions, such as states or parties, entitled to representation.

The page Mathematics of apportionment describes mathematical formulations and properties of apportionment rules.

Human settlement Community of any size, in which people live

In geography, statistics and archaeology, a settlement, locality or populated place is a community in which people live. The complexity of a settlement can range from a small number of dwellings grouped together to the largest of cities with surrounding urbanized areas. Settlements may include hamlets, villages, towns and cities. A settlement may have known historical properties such as the date or era in which it was first settled, or first settled by particular people.

Boundary delimitation is the drawing of boundaries, particularly of electoral precincts, states, counties or other municipalities. In the context of elections, it can be called redistribution and is used to prevent unbalance of population across districts. In the United States, it is called redistricting. Unbalanced or discriminatory delimitation is called "gerrymandering." Though there are no internationally agreed processes that guarantee fair delimitation, several organizations, such as the Commonwealth Secretariat, the European Union and the International Foundation for Electoral Systems have proposed guidelines for effective delimitation.

A law enforcement agency (LEA), in American English, is any government agency responsible for the enforcement of the laws.
