Twin cities (geographical proximity)
|This article needs additional citations for verification. (March 2011)|
Twin cities are a special case of two cities or urban centres that are founded in close geographic proximity and then grow into each other over time, losing most of their mutual buffer zone. The term Twin Cities in the United States refers specifically to the cities Minneapolis and Saint Paul which are in the midwestern state of Minnesota.
Cities twinned by proximity do not necessarily match demographically, economically, or politically.
In most cases, cities that grow into each other's space lose their individual identities, and the border or barrier that still separates them becomes almost irrelevant. An 1873 case of twin cities becoming united cities is Budapest in Hungary, which began as two settlements (Buda and Pest) facing each other across the Danube at a strategic fording place along a trade route. However, there are twin cities which have been able to resist this final union and have maintained individual identity against increased inter-city transport and typically converging economies and demographics.
Like any metropolises, twin cities may share an airport into whose airport codes are integrated the component initials e.g. DFW (Dallas–Fort Worth), MSP (Minneapolis–St. Paul), and CAK Akron-Canton, Ohio.
In some cases, such as Albury/Wodonga in Australia, the two cities are permanently divided by a state border, often one that strictly adheres to a geographical landmark, such as the Murray River that divides New South Wales from Victoria, and thus Albury from Wodonga.
