The old list on this page mixed genuine settlements with mobile-home parks and trailer courts
\n(Mason MH Park, Shawnee MH Court, Smittys Trailer Court) that are not places of record, and it
\nlisted Roachester twice. Both errors are fixed above. Monroe, Springboro, Carlisle, Loveland,
\nMiddletown and Blanchester each straddle Warren’s county line, so their population figures cover
\ntheir whole city or village, not just the Warren County share.<\/p>\n

Townships<\/h2>\n

Warren County has 11 civil townships. Washington is the only one with no incorporated
