Five more CDPs sit inside the county’s townships without a listed 2020 population count on this page: Darrtown and Collinsville (both Milford Township), Four Bridges and Olde West Chester (both West Chester Township), and Williamsdale and Woodsdale (St. Clair and Madison townships). Several places straddle county or state lines. Middletown and Monroe are both split between Butler and Warren counties, and the population figures above are citywide, not the Butler County share alone. Sharonville’s population is almost entirely in Hamilton County; only a small slice of the city, inside West Chester Township, is in Butler County. College Corner itself sits half in Butler County’s Oxford Township and half in Preble County’s Israel Township, and its built-up area continues across the Ohio–Indiana line into the separate town of West College Corner, Indiana.<\/p>\n
