The university also houses an independent nonprofit organization, Community Impact, which strives to serve disadvantaged people in the Harlem, Washington Heights, and Morningside Heights communities. From its earliest inception as a single service initiative formed in 1981 by Columbia University undergraduates, Community Impact has grown into Columbia University's largest student service organization. CI provides food, clothing, shelter, education, job training, and companionship for residents in its surrounding communities. CI consists of a dedicated corps of about 950 Columbia University student volunteers participating in 25 community service programs, which serve more than 8,000 people each year.
