Historically, this was common language in the profession and broader society. Because of its broad and common use, outdated language may also appear in other RISP products. The "R-word," as we understand it now, is an ableist slur. Our previous language does not reflect the RISP team's ongoing commitment to social inclusion of people with IDD.enPersons with Mental Retardation in State-Operated Residential Facilities: Years Ending June 30, 1984 and June 30, 1985 with Longitudinal Trends from 1950 to 1985Report
