About Custer County
Custer County is a county located in the southeast part of the U.S. state of Montana. As of the 2020 U.S. census, the population was 11,867. Its county seat and largest town is Miles City. The county was established after the end of the American Civil War (1861–1865), on June 2, 1865, as one of the nine original counties of the new western federal Territory of Montana, which had been formed the previous May 1864 by the United States Congress, with the approval of 16th President Abraham Lincoln. It was originally named Big Horn County of the old Montana Territory, and was renamed on February 16, 1877, in honor of Lieutenant Colonel George Armstrong Custer (1839–1876), commander of the famous 7th Cavalry Regiment of the United States Army, recently massacred and killed in the nearby Battle of the Little Bighorn, in the later portion of the American Indian Wars, the year before in June 1876.
Prepper Assessment
Custer County features a dry sub-humid climate with an annual mean temperature of 45.3°F and average rainfall of 14.5 inches per year. The growing season is moderate, supported by USDA zone 6b, allowing for a variety of crops to be cultivated. The terrain is characterized by open spaces and a low population density of 3.2 people per square mile, which may offer opportunities for self-sufficient living and privacy, though water availability could be a limiting factor given the aridity index of 0.72.
The area faces several notable natural hazards, including a high risk of cold waves (FEMA rank 87) and winter weather (rank 86), which could impact agricultural activities and daily living during the colder months. Wildfire risk is also significant (rank 85), which could pose threats to homesteaders. The county's high violence percentile (92/100) suggests a safer environment, but potential residents should consider the cost of living, with median home prices at $201,000 and an effective property tax rate of 1.06%.
This county is well-suited for those seeking a rural lifestyle with an emphasis on self-sufficiency, particularly individuals who can adapt to the challenges of a colder climate and potential natural hazards. It may not be ideal for those who prefer urban amenities or a milder climate, as the harsh winters and wildfire risks can be significant drawbacks. Enthusiastic homesteaders who prioritize privacy and open land may find hidden gems here, while those needing consistent access to broadband (only 60% of households) might face connectivity challenges.
