As of the 2010 Census, the city had a population of almost 150,000 residents. Juliet is well known for its multiple waterways including the Des Plaines River, Chase Lake, Michigan Beach, Jackson Creek and the DuPage River.

The major highways in and around the city include Interstates 55 and 80, US Highways 66, 52, 30, and 6, as well as Illinois Highway Routes 7, 53, and 59.
