Natural hazards pose significant risks in this region, with earthquakes ranked 74 and tornadoes at 67 on the FEMA scale. While the violence percentile is relatively low at 30, indicating a safer environment, the higher density percentile at 69 suggests a more populated area than some may prefer for homesteading. Additionally, the median home price of $192,800 may be a barrier for some potential homesteaders, particularly those seeking affordable land.
