Ten of the 15 most populous cities in the United States are located in coastal areas.
Delaware, Florida, and Texas are all a part of the United States’ coast. Fifty-three percent of the United States’ population lives in coastal areas. This means that more than half, or 53 out of every 100, U.S. citizens live in coastal areas.
Coastal areas attract many people. These areas have many natural resources, diverse animal and plant species, employment opportunities, recreation, tourism, trade routes, and energy and mineral production. p
