| A functional region or Nodal region, is a region that has a defined core that retains a specific characteristic that diminishes outwards. To be considered a Functional region, at least one form of spatial interaction must occur between the center and all other parts of the region. A functional region is organized around a node or focal point with the surrounding areas linked to that node by transportation systems, communication systems, or other economic association involving such activities as manufacturing and retail trading. A typical functional region is a metropolitan area (MA) as defined by the Bureau of Census. For example, the New York MA is a functional region that covers parts of several states. It is linked by commuting patterns, trade flows, television and radio broadcasts, newspapers, travel for recreation and entertainment. Other functional regions include shopping regions centered on malls, area served by branch banks, and ports. |
