Health in Rock County

via HealthByCounty

Rock County trails national life expectancy

At 76.3 years, Rock County residents live 1.5 years below the U.S. average, though the 15.8% poor/fair health rate is near national norms. This gap reflects demographic shifts, economic pressures, and health-limiting occupations that concentrate in the county's industrial base.

Below Wisconsin average health outcomes

Rock County's 76.3-year life expectancy trails Wisconsin's 77.8-year average by 1.5 years, while its 6.6% uninsured rate is one of the lowest in comparison counties. Strong insurance access masks underlying health disparities tied to income and employment patterns.

Middle performer with strong mental health access

Rock County's 76.3-year life expectancy matches Rusk County but trails Portage by 3 years; however, its 228 mental health providers per 100K is the highest in the region. Primary care availability at 51 per 100K is moderate, suggesting some residents face scheduling delays.

Insurance strength doesn't guarantee access

Rock County's 6.6% uninsured rate is among the lowest regionally, protecting most residents from catastrophic medical debt. However, 51 primary care providers per 100K means many appointments require weeks of waiting, and the 76.3-year life expectancy suggests chronic disease management remains uneven across the population.

Ensure continuous coverage

Rock County's strong insurance rates show what coverage can accomplish—but maintaining it is crucial, especially during job changes or family transitions. If your insurance status is uncertain, visit HealthCare.gov or Wisconsin Medicaid to verify enrollment; continuous coverage prevents gaps that derail treatment plans.

Disaster Risk in Rock County

Rock County faces elevated national risk

Rock County's composite risk score of 86.36 and Relatively Moderate rating place it among the most hazard-exposed counties in the nation. This south-central Wisconsin county's risk profile rivals some of America's most vulnerable regions.

Tied as Wisconsin's highest-risk county

Rock County's 86.36 score essentially ties Racine County (85.43) as Wisconsin's most hazard-exposed county, far exceeding the state average of 59.08. These two southern counties represent a distinct tier of elevated risk within Wisconsin.

Riskiest in its region by far

Rock County's 86.36 dramatically exceeds all nearby counties, including Richland (51.56), Sauk (72.11), and Racine (85.43). Its position in the state's vulnerable south-central corridor, combined with active severe weather patterns, creates a uniquely hazardous environment.

Comprehensive coverage is non-negotiable

Rock County homeowners must prioritize flood insurance, tornado-resistant construction upgrades, and earthquake coverage—a rare but warranted combination in Wisconsin. Work with an insurance professional to ensure your policy covers all three primary hazards and review it annually given the county's exceptional risk level.
