WASHINGTON — Pearl Brady has a stable job with good benefits and holds two degrees, a bachelor’s and a master’s. But despite her best efforts, she has no savings, and worries that it will be years before she manages to start putting away money for a house, children and eventually retirement.

“I’m in that extremely nervous category,” said Ms. Brady, 28, a Brooklynite who works for a union. “I know how much money I’m going to be making for the near term. I hope in my 30s and 40s to be able to save, but I have no idea how. It’s scary.”

Ms. Brady has plenty of company. A new study from the Urban Institute finds that Ms. Brady and her peers up to roughly age 40 have accrued less wealth than their parents did at the same age, even as the average wealth of Americans has doubled over the last quarter-century.

Because wealth compounds over long periods of time — a dollar saved 10 years ago is worth much more than a dollar saved today — young adults probably face less secure futures for decades down the road, and even shakier retirements.
