U.S. birth rate hits record high

ATLANTA (AP) — More babies were born in the United States in 2007 than any year in the nation’s history, topping the peak during the baby boom 50 years earlier, federal researchers reported Wednesday.

There is both good and bad news from the more than 4.3 million births:

UThe U.S. population is more than replacing itself, a healthy trend.

UHowever, the teen birth rate was up for the second year in a row.

The birth rate rose slightly for women of all ages, and births to unwed mothers reached an all-time high of about 40 percent, continuing a trend begun years ago. More than three-quarters of these women were 20 or older.

For a variety of reasons, it’s become more acceptable for women to have babies without a husband, said Duke University’s S. Philip Morgan, a leading fertility researcher.

Even happy couples may be living together without getting married, experts say. Some cited a growing trend among all adult women to have children regardless of their marital status.

The new numbers suggest the second year of a baby boomlet, with U.S. fertility rates higher in every racial group, the highest among Hispanic women. On average, a U.S. woman has 2.1 babies in her lifetime. That’s the “magic number” required for a population to replace itself.

Countries with much lower rates — such as Japan and Italy — face future labor shortages and eroding tax bases as they fail to reproduce enough to take care of their aging elders.

But it’s not clear the boomlet will last long. Some experts think birth rates are already declining because of the economic recession that began in late 2007.

“I expect they’ll go back down. The lowest birth rates recorded in the United States occurred during the Great Depression — and that was before modern contraception,” said Dr. Carol Hogue, an Emory University professor of maternal and child health.

The 2007 statistical snapshot reflected a relatively good economy coupled with cultural trends that promoted childbirth, she and others noted.

Meanwhile, U.S. abortions have been dropping to their lowest levels in decades, according to other reports. Some have attributed the abortion decline to better use of contraceptives, but other experts have wondered if the rise in births might indicate a failure in proper use of contraceptives. Some earlier studies have shown declining availability of abortions.

Cultural attitudes may be a more likely explanation. Morgan noted the pregnancy of Bristol Palin, the unmarried teen daughter of former GOP vice presidential candidate Sarah Palin. The young woman had a baby boy in December.

“She’s the poster child for what you do when you get pregnant now,” Morgan said.
