About HealthByCounty
Free, accurate health data for every US county.
Our Mission
HealthByCounty provides free, transparent health outcome and healthcare access data for every county in the United States. Whether you're considering a move, researching healthcare availability, or studying public health trends, you deserve access to clear, accurate data.
Data Sources
Our primary data source is the CDC County Health Rankings & Roadmaps, a collaboration between the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute. This program provides annual health data for nearly every county in the US.
Key metrics include life expectancy, percentage of adults reporting poor or fair health, uninsured rates, primary care provider ratios, and mental health provider ratios. Health scores (0-100) are composite metrics combining these factors — higher scores indicate healthier counties.
AI-Generated Content Disclosure
HealthByCounty uses AI (Claude by Anthropic) to generate descriptive narratives on state and county pages. These narratives summarize and contextualize underlying government data — they do not introduce new data points or medical claims.
All statistics, scores, rankings, and tables on this site are computed directly from government source data (CDC County Health Rankings, Census Bureau). AI is used only for prose narratives, not for data calculations or score generation. See our Methodology page for full details.
