CHELSEA, Mich. – Kristi and Michael Burns have a lot in common. They love crossword puzzles, football, going to museums and reading five or six books at a time. They describe themselves as mild-mannered introverts who suffer from an array of chronic medical problems. The two share similar marital résumés, too. On their wedding day in 2011, the groom was 43 and the bride 39, yet it was marriage No. 3 for both.
Today, their blended family is a sprawling, sometimes uneasy ensemble of two sharp-eyed sons from her two previous husbands, a daughter and son from his second marriage, ex-spouses of varying degrees of involvement, the partners of ex-spouses, the bemused in-laws and a kitten named Agnes that likes to sleep on computer keyboards.
If the Burnses seem atypical as an American nuclear family, how about the Schulte-Waysers, a merry band of two dads, six kids and two dogs?
The typical American family, if it ever lived anywhere but on Norman Rockwell's Thanksgiving canvas, has become as multilayered and full of surprises as a holiday turducken — the all-American seasonal portmanteau of deboned turkey, duck and chicken.
Researchers who study the structure and evolution of the American family express unsullied astonishment at how rapidly the family has changed in recent years, the transformations often exceeding or capsizing those same experts' predictions of just a few journal articles ago.
"This churning, this turnover in our intimate partnerships is creating complex families on a scale we've not seen before," said Andrew J. Cherlin, a professor of public policy at Johns Hopkins University.
Yet for all the restless shape-shifting of the American family, researchers who comb through census, survey and historical data and conduct field studies of ordinary home life have identified a number of key emerging themes.
Families, they say, are becoming more socially egalitarian overall, even as economic disparities widen. Families are more ethnically, racially, religiously and stylistically diverse than half a generation ago — or even half a year ago.
