Prepper Assessment

Living in this area offers a mix of suburban and rural characteristics, with a population density of 126.9 people per square mile and 25% of the land classified as rural. The climate is humid with an annual mean temperature of 50.8°F and an average annual rainfall of 37.6 inches, supporting a growing season suitable for various crops in USDA zone 7b. However, the cold winters, with lows averaging 16.1°F, may limit year-round outdoor activities and gardening.

The county faces notable natural hazards, including a high risk of cold waves (FEMA rank 94) and tornadoes (rank 69), which could impact self-sufficiency efforts. While the violence percentile is low at 5, indicating a safer environment, the disaster percentile of 66 suggests a moderate level of risk. Additionally, the median home price of $245,400 may be a barrier for those seeking affordable housing for homesteading.

This area may be suitable for individuals or families looking for a balance between rural living and access to urban amenities, particularly those who can manage the risks of natural disasters. However, it might not be ideal for those seeking extreme remoteness or lower housing costs. Homesteaders should be wary of the significant cold wave risk and consider the implications of higher property prices on their self-sufficiency plans.
