Cooperative Extension started in 1914, to help farmers, homemakers, and youth use the latest university research to improve their lives. At first geared towards strengthening rural areas, Cooperative Extension became integral to urban and suburban communities as well. A century later, Cooperative Extension continues to provide a vital link between public universities and communities.
