A small, aging, and predominantly local community
Thermopolis has around 2,700 residents, a predominantly white population of European descent, with a historic Indigenous presence tied to the nearby Wind River Reservation.
The population hovers around 2,700 people, with a median age that is high by American standards. Many residents are retirees or families who have lived in the area for generations, connected to cattle ranches, the local hospital, or the state park.
The ethnic composition is predominantly white, with German, English, and Scandinavian ancestry. Indigenous communities from the Eastern Shoshone and Northern Arapaho nations are present, as their Wind River Reservation lies just to the south, in Fort Washakie and Ethete. Hispanics form the second most visible group, primarily connected to the service and agricultural sectors.
English is the dominant language of daily life. Spanish appears in some families and businesses. Religiously, Protestant denominations predominate, with a Catholic presence and a community of The Church of Jesus Christ of Latter-day Saints, which is common throughout the American West.
