The same budget, placed two ways.
A limited number of new primary-care physicians can be spread across the country's shortage counties in different ways. Set how many, then compare ACWIS, which places them to reach the most people, against the common approach of filling the worst-ranked counties first. This runs on real county supply and population data.
Illustrative allocation on real county supply and population data (County Health Rankings 2026), optimising a transparent access target: people in counties lifted above HRSA's 1:3,500 primary-care line. It demonstrates the allocation logic, not a causal health outcome; on a partner's program data ACWIS optimises measured causal benefit with the same engine. Clearing every county-level shortage this way takes roughly 1,500 physicians; the space between the two lines is the cost of allocating by rank instead of by benefit.
