I am putting this here as much for my own reference as for yours, to examine the implications of this fact…
In 1978 , poor African-Americans, aged 12 and over were victims of violent crime at a rate of 45 per 1000; afluent African-Americans aged 12 and over were victims of violent crime at a rate of 38 per 1000.
By 2008, poor African-Americans aged 12 and over were victims of violent crime at a rate of 75 per 1000, and affluent African-Americans at a rate of 23 per 1000.
