Because women are having babies later and later, the number of parentless parents in America is skyrocketing. While life expectancy is also on the rise, it isn’t growing fast enough to guarantee the children born to these parents will have more time with their grandparents. What this means is that all of our assumptions about grandparents being around longer than ever before — because they’re living longer, after all — are simply inaccurate.

For the first time in U.S. history, millions of children (and their parents) are actually vulnerable to having less time with their grandparents than more. Between 1970 and 2007, the average age for a woman to give birth rose 3.6 years. During the same period, life expectancy for a 65-year-old increased 3.4 years. While that doesn’t seem earth-shattering on its own, consider another trend: While women overall are having fewer babies, mothers between 40 and 54 are having more. For example, 180,000 children were born to mothers 35 and older in 1972. Nearly 40 years later, that number soared to 603,113 — a 235 percent increase. This jump is so significant it can’t be explained away by increasing population size. Unquestionably, a revolution is happening in the way generations are connected in America.

This has massive consequences for every member of the family. Parents are raising kids without the support of their own mothers and fathers, and kids don’t have grandparents, with all the social, behavioral and cognitive benefits associated with these grandparent/grandchild relationships.

For the last three years, I’ve conducted one-on-one interviews, led numerous focus groups, and launched the Parentless Parents Survey, the first of its kind, which gathered responses from across the United States and a dozen countries, in order to study this growing population. Most shocking to me during this time is that I couldn’t find any research like it. Dozens of government institutions, committees and commissions are tasked with researching the changing landscape of the American family; yet while the American population is shifting in such a dramatic and measurable ways, no other investigation has been done on what these changes mean to parents and their children.

Here are some of my findings… (read the rest of the article here)
