Highlights of the federal report include:

• Married vs. single: The birthrate for single women fell for the third straight year, dropping by 3 percent from 2010 to 2011. The birthrate for married women, however, rose 1 percent.

• Minority groups: The birthrate for Hispanic women dropped a whopping 6 percent. It declined 2 percent for black women, stayed the same for whites and rose a bit for Asian-American and Pacific Islanders.

• In their 20s: Birthrates fell for women in their early 20s, down 5 percent from 2010 -- the lowest mark for women in that age group since 1940, when comprehensive records were first compiled. For women in their late 20s, birthrates fell 1 percent.

• In their 30s: Birthrates held steady for women in their early 30s, and rose for moms ages 35 and older.

• Teens: Birthrates for teens have been falling since 1991 and hit another low. The number of teen births last year -- about 330,000 -- was the fewest in one year since 1946. The teen birthrate fell 8 percent, and at 31 per 1,000 girls ages 15 through 19 was the lowest recorded in more than seven decades.
