Pregnancy rates, by age of woman: United States, 2000 and 2005

Pregnancy rates by age of woman are highest in 1990 and 2005 for women in their twenties, intermediate at ages 18–19 and 30–34 years, and lowest at ages under 18 and 35 years and older.

In 2005, an estimated 6,408,000 pregnancies resulted in 4.14 million live births, 1.21 million induced abortions, and 1.06 million fetal losses. The 2005 pregnancy rate of 103.2 pregnancies per 1,000 women aged 15–44 years is 11 percent below the 1990 peak of 115.8. The teenage pregnancy rate dropped 40 percent from 1990 to 2005, reaching an historic low of 70.6 per 1,000 women aged 15–19 years. Rates fell much more for younger than for older teenagers.
