It's time to update this out-of-date quote:
"In 2008, there were more than 106,000 live births in the United States to women ages 40 through 44, and 7,666 live births to women 45 to 54. In 2006, there were 2,274 live births to women over 42, using donor eggs."
Checking the 2009 birth stats today at the CDC and I found:
Age of mother
Women in their 40s -- The birth rate for women aged 40-44 rose 3 percent in 2009 from 9.8 in 2008 to 10.1 live births per 1,000 women - the highest rate reported since 1967.
Women aged 45-49 -- The birth rate rose 3 percent from 2008 to 2009 whereas their population fell slightly.
Women aged 50 and over -- The number of births to women aged 50 and over reached 569 in 2009, 5 percent above that in 2008

How old were the women who used ART in the United States in 2008?
Figure 3 presents ART cycles performed in the United States in 2009 according to the age of the woman who had the procedure. The average age of women using ART services in 2009 was 36. The largest group of women using ART services were women younger than 35, representing approximately 39% of all ART cycles performed in 2009. Approximately 20% of ART cycles were performed among women aged 35–37, 21% among women aged 38–40, 10% among women aged 41–42, 6% among women aged 43–44, and 5% among women older than 44.
How did the types of ART cycles used in the United States differ among women of different ages?
Figure 4 shows that, in 2009, the type of ART cycles varied by the woman’s age. The vast majority (97%) of women younger than 35 used their own eggs, whereas about 3% used donor eggs. In contrast, 36% of women aged 43–44 and 73% of women older than 44 used donor eggs. Across all age groups, more ART cycles using fresh eggs or embryos were performed than cycles using frozen embryos.
Number of live-birth deliveries to women using Donor Egg older than 43 in 2009: 806
So our updated quote becomes:
"In 2009, there were 105,827 live births in the United States to women ages 40 through 44 -- 7,320 live births to women 45 to 49 --and-- 569 live births to women 50-64.
In 2009, there were only 806 live births to women over 43, using donor eggs."
