Ada, in the county’s northeast corner, is Hardin County’s largest place by daytime population thanks to Ohio Northern University, though its year-round resident count trails Kenton. Several named crossroads — Foraker, Grant, Grassy Point, Hepburn, Holden, Huntersville, Jumbo, Jump, Maysville, Mentzer, Pfeiffer, Silver Creek and Yelverton — appear on county maps but have no population figures or ZIP codes of their own; they are served by the nearest listed post office town.<\/p>\n

Townships<\/h2>\n

Hardin County is divided into 15 civil townships. Individual 2020 township population figures were not verified for this profile, so populations are omitted rather than estimated.<\/p>\n
