# Riverside Township, Cook County, Illinois

Riverside Township is one of 29 townships in Cook County, Illinois, USA. As of the 2020 census, its population was 16,664.

## History

Riverside Township was established on September 24, 1870 by the Cook County Board, being split from portions of Proviso Township.
In 2023, during a debate on if all townships should be abolished across Cook County and possibly even Illinois, due to the perception of townships being an unnecessary tax burden to citizens, Riverside Township was used as a counter-example of a well run township which uses its taxes appropriately to service their community with a food bank and medical care. However, in township public support for the government remains low, mostly to a drastic township tax hike in 2021 which saw 70% of residents see a tax hike, with 43% of them seeing their taxes increase from $1,000 to $5,000.
