Prepper Assessment
Living in this area involves a mix of suburban and rural environments, with a population density of 384.2 people per square mile. The climate is classified as humid, with an annual mean temperature of 56.3°F and an average annual rainfall of 42.5 inches, suggesting a decent growing season for a variety of crops. However, the high humidity may pose challenges for certain crops. The county's USDA zone 8a indicates that it can support a range of gardening and farming activities, but land availability may be limited due to its proximity to St. Louis.
This area faces significant risks, particularly from natural hazards including heat waves and earthquakes, both ranked at 98 by FEMA. The county also experiences a high violence percentile at 88, which may raise concerns for safety. Additionally, the effective property tax rate is 2.17%, which could impact long-term affordability for potential homesteaders. With a prepper suitability score of only 9/100, the region's overall resilience to disasters is low, making it a less favorable location for those seeking self-sufficiency.
This county may be suitable for individuals who prioritize proximity to urban amenities while still wanting some rural lifestyle. Those who thrive here might have established careers in nearby cities and seek a suburban homestead. Conversely, individuals looking for a remote, low-density environment may find the population density and associated risks unappealing. The hidden gem for some could be the relatively affordable housing market, with a median home price of $158,500, but the high risks and lower suitability for self-sufficiency could be dealbreakers for serious preppers.
