Explanation:

Identify the historical demographic shift

The question asks to categorize US regions (Southwest, Northeast, Midwest, South) based on modern population shifts (typically comparing the "Sun Belt" growth to the "Rust Belt" decline, which affects congressional representation and political power).

Determine regional population trends

• Southwest and South (Sun Belt regions) have experienced rapid population growth, making them "more populous" and gaining congressional seats.
• Northeast and Midwest (Rust Belt regions) have experienced slower growth or relative decline, making them "less populous" relative to the growing regions and losing congressional seats.

Answer:

• Southwest: more populous
• Northeast: less populous
• Midwest: less populous
• South: more populous
