functional/nodal region
(nodal) an area organized around a focal point
In geography and urban planning, a functional/nodal region is a region defined by the interconnectedness of economic, social, and cultural activities and infrastructure. In other words, it is an area where there is a significant flow of people, goods, and ideas because of the concentration of economic, social, and cultural activities.
Functional/nodal regions do not necessarily have defined boundaries. Instead, they are usually identified based on the presence of a central point, which serves as a hub or node for the region. This central point can be a major city or town that acts as a regional center for trade, commerce, and transport.
For example, the New York City metropolitan area is a functional region that encompasses several counties in New York, New Jersey, and Connecticut, all of which are characterized by strong economic, social, and cultural ties to the city. Similarly, the European Union is a functional region that encompasses several countries that share a common political and economic infrastructure.
In summary, a functional/nodal region is a geographic area where economic, social, and cultural activities are interconnected and flow to and from a central hub or node.
