Woosung is a tiny rural community in Ogle County, Illinois, with just 93 residents across 52 households. The median age of 51.8 years and small household size of 1.8 people per home suggest an aging population of singles and couples. This isn't a growing town.

The street layout is minimal. Griswold Street is the main thoroughfare with 6 delivery points, including some apartments. Central Street, Canton Street, and six other streets make up the rest of the tiny grid. There are no business establishments or employees recorded in census data for this ZIP code. The population is 96% White (89 residents), with 17% identifying as Hispanic (16 residents).
