Gray Nation: The Very Real Economic Dangers of an Aging America

Two economists envision a scary -- and scarily realistic -- future where the working population expands slower and slower, and jobless recoveries are the only recoveries we know

In the future, U.S. growth will be slower. Recessions will be deeper. Recoveries will be weaker. And there's exactly one thing to blame.

Demographics.

That's the stark conclusion from James Stock and Mark Watson in this fascinating, and occasionally depressing, new paper. In fact, they say, the future is now. For the last few years, we've weathered the beginning of what demographers have called the grey tsunami. "Most of the slow recovery [in today's job market] is attributable to a long-term slowdown in trend employment growth," Stock and Watson write.

The authors blame two demographic demons for our uncertain future: (1) the plateau in the female labor force participation rate, and (2) the aging of the U.S. workforce. Their underlying logic is that without continued growth in female workers or a significant boost in population, employment and GDP growth will slow, leaving us vulnerable to recessions with "steeper declines and slower recoveries." In such a future, jobless recoveries will be the only recoveries we know.

Demographic Demon #1
WOMEN'S PARTICIPATION RATE

In the first half of the 20th century, female employment wasn't exactly a high-priority concern for policy makers. For the first 20 years of the century, women didn't have the right to vote. For the next 30 years, they barely made up a fifth of the labor force. Then everything changed.

The ascendance of women in the workforce was perhaps the singular cultural/economic triumph of the second half of the 20th century. In 1960, just four in ten working-age women were active in the labor force. By 1990, it was more like six in ten (see graph below of female participation rates). By 2010, women made up a majority of the workforce. But that growth appears to have hit a ceiling. The female participation rate in early 2011 was the same as in 1994. In that time, the male participation has fallen. That's not good news for a country that will require more workers to both grow the national pot of money and provide for an aging population transitioning out of the workplace.

Demographic Demon #2
THE GRAYING OF AMERICA

Famous economic worrywart Thomas Malthus famously predicted that population growth would get in the way of economic growth, because we wouldn't be able to make enough stuff to keep everybody healthy and happy. What's fascinating about the threat of a gray society is that it turns Malthusian pessimism on its head. In fact, the more reasonable threat we face is that an aging population will require more resources that can be -- and must be -- provided by more people.

Let's take the long view. In 1950, there were more Americans under 25 than over 45. By 2050, the share of seniors will nearly treble while the country's portion of twentysomethings will decline. Here's a look at 100 years of America aging, from a National Journal/Atlantic special report:

"Now we've gone to the other extreme, and it's clear that young people are the scarce resource. In the 21st century, the U.S. could be the slowly aging leader of a rapidly aging world."

Here's another way to see what Brooks, Stock, and Watson are concerned about. In the late 1990s, a remarkable 67% of the country (16 and over) was working or seeking work. That number has fallen steadily in the last decade for two reasons. First, there's the Great Recession, which pushed people out of the labor force. But as you can see in the graph below, demographers were already expected labor participation to decline due to demographics. As 80 million Boomers move into retirement, a smaller share of our population will be working ... and a rising share will be seeking increasingly expensive medical attention from the workforce that is left over. That adds up to a less dynamic economy.
