Nonprofit, nonpartisan organization that addresses the needs and interests of Americans aged 50 and older. It was founded in 1958 by a retired teacher, Ethel Andrus, and merged in 1982 with the National Retired Teachers Association, also founded by Andrus (1947). Its bimonthly magazine, Modern Maturity, has the largest circulation of any U.S. periodical. Its membership exceeds 35 million. Its members' reliably high turnout at the polls has made it one of the most powerful lobbying groups in the country.
