Territorial units are defined areas of land that are used for administrative purposes. These units can vary in size and function, ranging from small neighborhoods to large regions or countries. They help organize governance, resource management, and public services within a specific geographic area. Examples of territorial units include cities, counties, states, and countries. Each unit typically has its own local government and regulations, allowing for tailored management of resources and services. Understanding these units is essential for effective planning and development in various sectors, including education, transportation, and healthcare.
