Final answer:
A large region or administrative district can be referred to as a formal region in geography, similar to a state or province, with well-defined governmental or administrative boundaries.
Step-by-step explanation:
A large region or administrative district similar to a state or province can be referred to as a formal region. This term is often used in geography to describe an area defined by official boundaries, which could be governmental, administrative or political. For instance, comparing these regions to Kentucky in the United States, which is a state with a population of approximately 4.5 million and a physical area of 40,409 square miles can provide a reference point for size and population. Additionally, some regions may have special statuses such as Hong Kong in China or Puerto Rico in the United States which are semi-autonomous or have different sets of rules.
Formal regions encompass a variety of administrative divisions such as states, provinces, and directly controlled municipalities like Beijing or Shanghai in China. These regions have well-defined boundaries that are recognized by law and can vary in size and governance. Geographers and political scientists study these regions to understand the distribution of resources, political systems, cultural traits, and various governance models across the globe.
