Nearly 1 in 2 Americans has had an immediate family member incarcerated, with Black people being more likely than white and Hispanic people to experience this. That’s a problem, in part, because having a relative in prison is expensive.

According to a report released this week from FWD.us, an advocacy organization aimed at criminal justice reform, having a loved one in prison or jail is estimated to cost families across the country nearly $350 billion each year — about four times the amount the federal government estimates it costs taxpayers annually to operate the nation’s prisons and jails.

On average, people with a family member behind bars spend around $4,000 a year on their incarcerated loved ones, the report says.
