The population was 16,203 at the 2000 census. Neumann University (est. 1965), a private co-educational Franciscan college located on the grounds of Our Lady of Angels Convent, is located in the northern portion of the township. Down the road from Neumann University is IceWorks Skating Complex, where the Neumann University Men’s and Women’s Ice Hockey teams play their home games.
