Using 2007 National Crime Victimization Survey data, BJS estimates that about one third (34%) of the crimes against persons with or without a disability in 2007 were serious violent crimes (rape/sexual assault, robbery, or aggravated assault). Persons with disabilities were victims of about 47,000 rapes.  Rates of rape and sexual assault were more than twice those for people without disabilities. Youth with a disability ages 12 to 19 experienced violence at nearly twice the rate as those without a disability. People with cognitive disabilities had a higher risk of violent victimization than persons with any other type of disability. Nearly 1 in 5 violent crime victims with a disability believed that they became a victim because of their disability.
