Prepper Assessment

Living in this area offers a mix of suburban and rural environments, with a population density of 228.4 people per square mile. The climate features an annual mean temperature of 47.8°F, with a growing season suitable for USDA zone 7a. Precipitation averages 37.4 inches per year, providing ample water for self-sufficient living. However, the cold winters, with lows around 12.4°F, can pose challenges for year-round gardening and livestock care.

The county faces notable natural hazards, including a high risk of hail (96) and tornadoes (94), which could impact structures and crops. Additionally, the disaster percentile is ranked at 86, indicating a higher likelihood of experiencing severe weather events. While the violence percentile is relatively low at 12, the overall density percentile at 84 suggests a more populated environment, which might not appeal to those seeking extreme remoteness. Housing prices are moderate, with a median home value of $193,000.

This county may suit individuals or families looking for a balance between rural and suburban life, as well as those who can manage the risks of severe weather. Homesteaders with experience in adapting to cold climates and severe storms may thrive here. However, those seeking complete isolation or who are unprepared for the potential hazards may find this area challenging. The effective property tax rate of 1.81% is a consideration for budget-conscious homesteaders.
