Three places on this list straddle county lines. Fostoria’s population figure above is
\ncitywide — most of the city sits in Seneca County, but it also reaches into Hancock and
\nWood counties. Bellevue’s 8,249 residents are spread across four counties (Erie, Huron,
\nSandusky and Seneca), with only a slice of the city inside Seneca. McCutchenville straddles
\nSeneca and Wyandot counties, with the larger share of its households in Wyandot. Green Springs
\nalso splits, sitting in both Sandusky and Seneca counties.<\/p>\n
