Research from the Arizona Children of Prisoners Bill of Rights Project (2007) showed that just in my winter home state of Arizona, there were 175,000 children with parent/s in jail, prison, or on probation. The discussions and focus groups they conducted indicated that these children often lacked food, shelter, clothing, parental guidance, good role models, love, societal acceptance, a basic sense of security, and stability in their lives. The absence of these basic nutrients almost invites a child into a life of crime for survival. Research indicates these children are six times more likely than other children to become incarcerated at some point in their lives.
To learn more about opportunities for man-making with this very needy population contact the Resource Center. They are a provider for the federal Corporation for National and Community Service. The Resource Center's site offers lots of background information, links to related topics, and suggested volunteer opportunities.
You can also just do a Google search on Mentoring the Children of Prisoners in your state and see what comes up. If you want to be on the front lines of man-making, this could be a very good place to begin.
