The city of Niles lies mostly within the boundaries of township, but is administratively autonomous. There are no other incorporated municipalities in the township. Much of the township is considered to be part of either the Niles urban area or the South Bend, Indiana, urban area.

Bertrand is an unincorporated community in the southern part of the township at 41°46′27″N 86°15′45″W / 41.77417°N 86.26250°W / 41.77417; -86.26250 (Bertrand) on the St. Joseph River approximately 4 miles (6 km) south of Niles. Joseph Bertrand, a French Canadian, had a trading post here by 1812. He had married the daughter of a Potawatomi chief and through her had acquired land. After the Potowatomi ceded their lands to the federal government with the 1833 Treaty of Chicago, Daniel G. Garnsey obtained the permission of U.S. President Andrew Jackson and the consent of Mrs. Bertrand to locate a village on her land. Alonzo Bennett platted the village of Bertrand in 1833 and became its first postmaster on June 9, 1834. The town was a stop on the Detroit-Chicago road. In 1844, the Sisters of the Holy Cross founded their first convent in the United States here. The town gradually declined after it was by-passed by railroads. The post office closed on April 15, 1901.  

The township is irregularly-shaped, with a southern appendage consisting of a small portion of land lying between the St. Joseph River on the west and Cass County on the east and the Indiana state line to the south.
