As of the 2020 census, its population was 41,514,[2] with approximately 71% of that total living in the city of Burbank (pop.

792),[5] and the largely industrial eastern half of Bedford Park, as well as some small portions of Bridgeview.

The unincorporated communities of Central Stickney and Nottingham Park are also within the township.

Stickney Township's approximate borders are Pershing Road (39th Street) on the north, Cicero Avenue on the east, 87th Street on the south, and Harlem Avenue on the west, excepting those areas in the Chicago communities of Garfield Ridge and Clearing (which include Chicago Midway International Airport), but also including the area between Laramie and Cicero Avenues as far north as 35th Street, where Hawthorne Race Course is located.

The Chicago Sanitary and Ship Canal, designated a National Historic District in 2011, passes through the northwest corner of the township.

What became the southwest projection of the city of Chicago was within this township geographically until the area was annexed.

22.50% of all households were made up of individuals, and 10.70% had someone living alone who was 65 years of age or older.
