Healthiest Cities & Counties Challenge

The National Association of Counties (NACo) is partnering with the Aetna Foundation, the American Public Health Association (APHA) and CEOs for Cities on a $1.5 million prize competition, the Healthiest Cities & Counties Challenge (the Challenge). Submit a proposal for the Challenge, which aims to improve measurable health outcomes and promote health, wellness, equity and social interaction through practical, evidence-based strategies and cross-sector collaboration.

Cities and counties selected to participate in the Challenge must have strong cross-sector teams focused on public health issues that reflect community priorities. Challenge participants that demonstrate measurable results are eligible to win up to $500,000. The deadline for submitting a proposal is May 31 at 5 p.m. EDT. For more information, visit

Counties and cities involved in the Challenge will work to improve their residents’ health by incorporating health considerations into policies and practices, developing replicable strategies that achieve measurable results and creating sustainability by leveraging prize money from the Challenge.

All counties and cities are eligible to submit a proposal for the Challenge.* There are two tiers of participants based upon population size.

Tier 1 – counties and cities with populations between 65,000 and 250,000.
Tier 2 – counties and cities with populations between 250,001 and 600,000 AND counties and cities with populations over 600,000 whose proposal targets a segment of their population that is between 65,000 and 600,000.

*Counties and cities with less than the minimum population of 65,000 are also eligible to submit a proposal if they partner with another county or city and their combined population is between 65,000 and 600,000.
