- In 2000, of the 281 million people that lived in the U.S., more than 148 million people lived in coastal counties.
- Coastal counties contain 53% of the nation's population, yet, excluding Alaska, only account for 17% of U.S. land area.
- From 2000 to 2015, coastal county population is expected to increase by 17 million people; 22 of the 25 most densely populated counties are coastal.
- Coastal counties average 291 persons per square mile (not including Alaska), over five times greater than the population density of noncoastal counties.
