BARACK OBAMA was raised by his grandparents for part of his childhood. He remembers his grandmother as being “tough as nails”. Clarence Thomas, a Supreme Court judge, was raised by his grandparents because his mother could not make ends meet. He called his grandfather “the greatest man I have ever known”. Grandparents have always reared children when need arose. Most have done it well. A few have done it badly–the late comedian Richard Pryor, who was raised by his grandmother in a brothel she owned, was constantly beaten.
What is new is that, as the nuclear family frays, grandparents are taking more and more of the strain. Of the 75m children in America, 5.5m live in households headed by grandparents, a number that has risen by almost a million since 2005, according to the Census bureau. Beware stereotypes. Child-rearing grandparents are disproportionately black, but in absolute terms most are white, live above the poverty line and own their own homes. When a parent loses a job or cannot pay the mortgage, many families move in with grandma. Sometimes, however, the parents have disappeared: an estimated 900,000 children are being raised solely by grandparents.
