The Community Service Society of New York (CSS) is an informed, independent, and unwavering voice for positive action on behalf of more than 3 million low-income New Yorkers. CSS draws on a 175-year history of excellence in addressing the root causes of economic disparity through research, advocacy, litigation, and innovative program models that strengthen and benefit all New Yorkers.

The Community Service Society of New York was formed in 1939 by the merger of two venerable social service agencies: The New York Association for the Improvement of the Condition of the Poor (founded in 1843) and the Charity Organization Society (founded in 1882).
