Urban hierarchy refers to the organization of cities and towns based on their size, function, and the services they provide. Larger cities, like metropolises, typically offer more specialized services, such as advanced healthcare and higher education institutions, while smaller towns may provide only basic services. This structure helps to understand how urban areas interact and support each other economically and socially. In an urban hierarchy, cities are often categorized into levels, such as hamlets, villages, towns, and cities. Each level serves a different role in the regional economy, with larger cities acting as central places that attract people and resources from smaller surrounding areas. This system helps planners and policymakers make informed decisions about resource allocation and development.
