ACORN, the Association of Community Organizations for Reform Now, is the largest community organization of low and moderate-income families in the United States. ACORN has an active membership of over 160,000 families, organized into more than 750 neighborhood chapters in more than 60 cities across the country. As a community group, ACORN is non-profit, non-violent, and nominally non-partisan. The organization was born out of the civil rights movement. ACORN was founded by Wade Rathke, a community and labor organizer, in 1970. The current national president of ACORN is Maude Hurd.
