The nearby townships of Kinzua and Corydon, having greatly reduced populations, were merged into Mead in 1963 and 1964, respectively.

The Allegheny Reservoir forms the entire western border of Mead Township's northern arm.

The racial make-up of the township was 99.10% White, 0.06% African American, 0.06% Asian, 0.06% Pacific Islander and 0.71% from two or more races.

25.9% of all households were made up of individuals and 11.2% had someone living alone who was 65 years of age or older.
