Against the trend, US births way up

Some complain that many illegal immigrants come here purposely to have children.
"The child is an automatic American citizen, thus entitled to all benefits of American citizens. This gives a certain financial incentive for people coming from other countries illegally to have children here," said John Vinson, president of the Virginia-based American Immigration Control Foundation.
Fertility rates were also relatively high for other racial and ethnic groups. The rate rose to 2.1 for blacks and nearly 1.9 for non-Hispanic whites in 2006, according to the CDC.
Fertility levels tend to decline as women become better educated and gain career opportunities, and as they postpone childbirth until they are older. Experts say those factors, along with the legalization of abortion and the expansion of contraception options, explain why the US fertility rate dropped to its lowest point -- about 1.7 — in 1976.
But while fertility declines persisted in many other developed nations, the United States saw the reverse: The fertility rate climbed to 2 in 1989 and has hovered around that mark since then, according to federal birth data.
Hans-Peter Kohler, a University of Pennsylvania sociology professor, and others say the difference has more to do with culture than race. For example, white American women have more children than white European -- even though many nations in Europe have more family-friendly government policies on parental leave and child care.
But such policies are just one factor in creating a society that produces lots of babies, said Duke University's S. Philip Morgan, a leading fertility researcher.
Other factors include recent declines in contraceptive use here; limited access to abortion in some states; and a 24/7 economy that provides opportunities for mothers to return to work, he said.
Also, it is more common for American women to have babies out of wedlock and more common for couples here to go forward with unwanted pregnancies. And, compared with nations like Italy and Japan, it's more common for American husbands to help out with chores and child care.
There are regional variations in the United States. New England's fertility rates are more like Northern Europe's. American women in the Midwest, South and certain mountain states tend to have more children.
The influence of certain religions in those latter regions is an important factor, said Ron Lesthaeghe, a Belgian demographer who is a visiting professor at the University of Michigan. "Evangelical Protestantism and Mormons," he said.
