What this measures

The estimated percentage of adults who women aged 50 to 74 had a mammogram in the past two years. It is adjusted so places with older or younger populations can be compared fairly. It is an estimate from a statistical model, not a direct count from a local survey. Source: CDC PLACES.

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.
