ANALYSIS: Fear of Economic Blow as Births Drop Around the World

NEW YORK (AP) -

The 2008 financial crisis did more than wipe out billions in wealth and millions of jobs. It also sent birth rates tumbling around the world. Six years later, birth rates haven’t bounced back.

For those who fear an overcrowded planet, this is good news. For the economy, not so good.

We tend to think economic growth comes from working harder and smarter. But economists attribute up to a third of it to more people joining the workforce each year than leaving it. The result is more producing, earning and spending.

Now, this secret fuel of the economy, rarely missing and little noticed, is running out.

“For the first time since World War II, we’re no longer getting a tailwind,” says Russ Koesterich, chief investment strategist at BlackRock, the world’s largest money manager. “You’re going to create fewer jobs. … All else equal, wage growth will be slower.”

Births are falling in China, Japan, the United States, Germany, Italy and nearly all other European countries. Studies have shown that births drop when unemployment rises, such as during the Great Depression of the 1930s. Birth rates have fallen the most in some regions that were hardest hit by the financial crisis.

The trend emerges as a gauge of future economic health – the growth in the pool of potential workers, ages 20-64 – is signaling trouble ahead. This labor pool had expanded for decades, thanks to the vast generation of baby boomers. Now the boomers are retiring, and there are barely enough new workers to replace them, let alone add to their numbers.

Growth in the working-age population has halted in developed countries overall. Even in France and the United Kingdom, with relatively healthy birth rates, growth in the labor pool has slowed dramatically. In Japan, Germany and Italy, the labor pool is shrinking.

“It’s like health – you only realize it exists until you don’t have it,” says Alejandro Macarron Larumbe of Demographic Renaissance, a think tank in Madrid.

The effects on economies, personal wealth and living standards are far-reaching:

– A return to “normal” growth is unlikely: Economic growth of 3 percent a year in developed countries, the average over four decades, had been considered a natural rate of expansion, sure to return once damage from the global downturn faded. But many economists argue that that pace can’t be sustained without a surge of new workers. The Congressional Budget Office has estimated that the U.S. economy will grow 3 percent or so in each of the next three years, then slow to an average 2.3 percent for the next eight years. The main reason: not enough new workers.

– Reduced pay and lifestyles: Slower economic growth will limit wage gains and make it difficult for middle-class families to raise their living standards, and for those in poverty to escape it. One measure of living standards is already signaling trouble: Gross domestic product per capita – the value of goods and services a country produces per person – fell 1 percent in the five biggest developed countries from the start of 2008 through 2012, according to the World Bank.

– A drag on household wealth: Slower economic growth means companies will generate lower profits, thereby weighing down stock prices. And the share of people in the population at the age when they tend to invest in stocks and homes is set to fall, too. All else equal, that implies stagnant or lower values. Homes are the biggest source of wealth for most middle-class families.
