This article published in Newsweek shows how places like North Dakota and West Virginia are the most “over-crowded” with visitors (compared to local population sizes), underscoring the need to ensure the local infrastructure is ready to meet demand.

West Virginia, with its 1.77 million residents, welcomes approximately 75 million visitors annually. Its reputation for outdoor adventures such as whitewater rafting, hiking, and rock climbing has made it a year-round draw. The result is a tourism pressure ratio of over 42 to 1, making it the nation’s most-saturated state by tourist volume per capita.

Rounding out the top-five most-overcrowded states are North Dakota (33 tourists per resident), Delaware (28), Rhode Island, and Vermont. Many of these states have relatively small populations, amplifying the effect of tourism surges.
