Common Methods For Defining The Boundaries of A City
- Urban Area
- "City" defined as a physically contiguous urban area, without regard to territorial or other boundaries. The delineation is usually done using some type of urban density, such as population density or density of buildings (for example, "gaps between structures may not exceed 200 metres"). Satellite and/or aerial maps may be used. For statistical convenience, such areas are sometimes adjusted to appropriate administrative boundaries, yielding an agglomeration.
- Metropolitan Area
- "City" as defined by the habits of its demographic population, as by metropolitan area, labour market area, or similar. Such definitions are usually based on commuting between home and work. Commuter flow thresholds into the core urban area are established by the national census authority, determining which areas are included.
- City Proper (Administrative)
- "City" as strictly defined by a given government (city proper). Typically based on a municipality or equivalent entity, or sometimes a group of municipalities under a regional government.
