Towns with the most-used libraries in Pennsylvania

New Cumberland has the most-used library of Pennsylvania’s 108 towns of 2,500+ with a library of their own: 16.5 visits per resident a year at New Cumberland Public Library (IMLS Public Libraries Survey). The typical library here counts 3.2.

IMLS Public Libraries Survey: a year’s visits divided by the people the library serves. Only a library that serves one town (80–125% of its population) and reported its own count is ranked; IMLS estimates never are. A described list: no letters. How grades work
