What it’s like

The place. Guernsey is a small town in Platte County, Wyoming, where neighbors tend to know one another. Winters are cold, with the coldest weather in January, and summers turn properly hot by July. The year brings little rain and melted snow, so the air is dry and the landscape open. A four-year degree is less common among adults here than in many places, and a typical home costs less than in much of the country.

Work. Residents work mostly in schools, hospitals and social care, with others in the building trades, in transport, warehouses and utilities, and in restaurants, hotels and entertainment. Across Platte County, the largest workplaces include the Platte County School District and Platte County Memorial Hospital, a critical access hospital. Unemployment across the county is a little lower than a year ago, and the number of jobs has edged up slightly.

Things to do. Guernsey State Park is a protected area a short drive away, the easiest outing from town. A longer drive leads to Fort Laramie National Historic Site, a protected area with a long frontier history. Glendo Reservoir is also a longer drive away, and the Laramie River is another option for time by the water.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Guernsey’s census tracts, against the rest of the country; all of them together, relatively moderate. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.

From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Platte County.
