The Robert Wood Johnson Foundation and University of Wisconsin have teamed up to rank almost every county in the nation, state by state, based on overall health and the factors that affect it.
The teleconference will run from 10 a.m. to 11 a.m. Eastern, and will be followed at 2 p.m. by a Twitter Q&A. Register online. The rankings are embargoed until 12:01 a.m. Eastern on March 30.
