Question

The U.S. countries that border Mexico have an unusually high percentage of people in which age group

Answer 1

The U.S. states that border Mexico—California, Arizona, New Mexico, and Texas—have a higher percentage of young people compared to the national average. This is largely due to demographic factors, including higher birth rates in Hispanic communities and immigration trends. As a result, you might find that these states have a notable percentage of their populations in the younger age groups, particularly those under 18.
