The YMCA has been serving communities since 1844 through various programs and locations across the Chicago area. It focuses on four mission areas: academic readiness, character development, violence prevention, and fitness/healthy living. It addresses issues in these areas through programs like after-school care, fitness classes, camps, and more. The YMCA measures its impact through assessments of participants and publishes an annual report. It relies on membership fees, donations, and other funds to operate its wide-ranging programs and services across the Chicago region.
