You are not alone - some stats about older dads

Because, of course, all guys like stats, here are some numbers from the Centers for Disease Control that reflect the trend toward older dads. According to the CDC's most recent data, between 1980 and 2003 the number of live births per 1,000 men decreased in males between 15 and 29. But the birth rate increased for that time period for almost all age categories 30 and over. For men 40 to 44 years old, the number of live births per 1,000 men increased from 17.1 to 23.4. For men 45 to 49, the number of births increased from 6.1 to 7.6. For men 50 to 54 years, the number increased from 2.2 to 2.5. The only category where there wasn't an increase was men 55 and older, which stated the same: 0.3 births per 1,000 men.

Of course, there is a parallel trend for women. As the CDC notes:

"Births to older women continue to increase. From 2003 to 2004, the birth rate for women aged 30–34 years increased slightly (less than 1 percent) while the rate for women aged 35–39 years rose by 4 percent. The birth rate for women 40–44 years increased 3 percent, to 9.0, and the rate for women aged 45–49 years increased in 2004 to 0.6 births per 1,000 women."

There's an interesting book called Exposing Men:The Science and Politics of Male Reproduction by Cynthia Daniels, an assistant professor of Political Science at Rutger University. It's published by Oxford University Press. There's an interview with her on the Living on Earth web site. Is there a cost to all this late fathering????
