The climate features an annual mean temperature of 47.2°F and receives about 36.1 inches of rain per year, providing a moderate growing season suitable for various crops in USDA zone 7a.

The county faces several natural hazards, as indicated by its FEMA ratings, with hail (93) and tornado (86) being notable threats. The disaster percentile is relatively high at 76, suggesting a higher likelihood of encountering severe weather events. Additionally, with a median home price of $238,300 and an effective property tax rate of 1.64%, the cost of living may be a concern for some potential residents. Despite a lower violence percentile of 8, the overall population density could lead to some community-related challenges.

Homesteaders who thrive in a community-oriented environment may find opportunities here, while those seeking complete solitude or an entirely self-sufficient lifestyle may find the population density and potential hazards to be dealbreakers.
