"Among white children in 1980, only 0.4 of 1 percent had an incarcerated parent; by 2008 this figure had increased to 1.75 percent. Rates of parental incarceration are roughly double among Latino children, with 3.5 percent of children having a parent locked up by 2008. Among African American children, 1.2 million, or about 11 percent, had a parent incarcerated by 2008."
