A region in the United States known for substantial population growth due to retiring baby boomers and immigrants

• A. Sunbelt
• B. Rust Belt
• C. Great Plains
• D. New England

Answer: (A)

The Sun Belt is the region known for that kind of rapid population growth. It spans the southern tier of the United States and has attracted lots of retirees and immigrants. After World War II, people moved to warmer climates for affordable housing, new jobs, and growing communities. As the baby-boom generation has aged into retirement, many have chosen Sun Belt states like Florida, Arizona, Nevada, and Texas, boosting population even more. Immigrant communities have also settled in these areas for work opportunities, compounding the growth. In contrast, the Rust Belt saw manufacturing declines, the Great Plains are more rural and slower-growing, and New England has aging populations and slower growth, so they don’t fit the described pattern as well.
