What this measures
Deaths of babies before their first birthday per 1,000 babies born alive. Source: County Health Rankings.
For most measures, a national ranking mostly sorts places by income and by how urban they are. Each county’s own page compares it with the 50 counties most like it instead, which is often the fairer view.
