From USA Today — 

It’s always been a sort of final chapter of the American dream: Get married and have kids. Buy a house. Move to a bigger house. Downsize to a smaller one.

But a growing number of aging baby boomers are saying, “No, thanks” to downsizing, choosing instead to remain in the same sprawling houses in which they raised kids and created lifelong memories.

“We’re just not seeing that much downsizing,” says Alexandra Lee, a housing data analyst at Trulia, a real estate research firm.

While many older Americans are still stepping down to smaller homes, they’re doing so later in life. The trend is contributing to a housing supply shortage across much of the country.

A more modest home typically means less upkeep and a potential financial windfall as a big chunk of the proceeds from the sale of the larger property can help bolster retirement nest eggs.

Boomers, however, are defying the traditional bounds of advancing age just as they rebelled against the establishment in the 1960s and work- and family-centered values in the 1970s in favor of self-fulfillment.

“They have refused to follow what the traditional expectations were,” says Barbara Risman, a sociology professor at the University of Illinois at Chicago.
