The Band membership is an amalgamation of three bands, Wikwemikong, South Bay, and Point Grondine, and consists of three tribal backgrounds. The people are originally Odawa, with arrivals of Pottawatomi in 1836 and Ojibway after 1850.
The most recent population statistics available (December 31, 2009) state that Wikwemikong has a total Band membership of 7278. Approximately 3030 of this number reside on-reserve, 78 band members of other bands lived on reserve with the remaining 4248 residing either on other reserves or off-reserve completely.
The population is spread across the reserve into several settlements, or satellite communities, including Kaboni, Buzwah, South Bay, Rabbit Island, Murray Hill, Cape Smith, and Wikwemikongsing.
