In most English-speaking regions, suburban areas are defined in contrast to central or inner city areas, but in Australian English and South African English, "suburb" has become largely synonymous with what is called a "neighborhood" in other countries and the term extends to inner city areas. In some areas, such as Australia, China, New Zealand, the United Kingdom, and a few U.S. states, new suburbs are routinely annexed by adjacent cities. In others, such as Arabia, Canada, France, and much of the United States, many suburbs remain separate municipalities or are governed as part of a larger local government area such as a county.  - Ekeren is a northern district of the municipality of Antwerp in the Flemish Region of Belgium. The suburb celebrated its 850th birthday in 2005; the name of the town was first mentioned in 1155, as "Hecerna".
