Which option describes an urbanized area as defined by population and density?

• A. It has 50,000 or more population with a core density of 2,000 per square mile
• B. It has 10,000 or more population with a core density of 2,000 per square mile
• C. It has 25,000 or more population with a core density of 1,500 per square mile
• D. It has 50,000 or more population with a core density of 1,000 per square mile

Answer: (D)

An urbanized area is defined by a combination of population size and how densely that population lives in the core. Specifically, it must have at least 50,000 people and the core area must reach a density of 1,000 or more people per square mile. The option that states 50,000 or more people with a core density of 1,000 per square mile matches both criteria exactly, so it best describes an urbanized area by this definition. The other choices fall short either on population (too few people) or on the density specification not aligning with the defined threshold in this item.
