Preliminary birth data for 2003 indicate that the birth rate for women aged 40-44 years increased in 2003 while the rate for women aged 45-54 years remain unchanged, according to a new report by the Centers for Disease Control and Prevention. This is the first time that births to women over 40 topped 100,000 in a single year.
The report, “Births: Preliminary Data For 2003,” shows that birth rates for women aged 40-44 years rose 5 percent between 2002 and 2003 from 8.3 to 8.7 births per 1,000 women. The rate for women aged 45-54 years remained unchanged at 0.5. The birth rate for women aged 40-44 years has more than doubled since 1981.
Other findings in the report include:
- Birth rates for women aged 30-34 years increased by 4 percent from 2002 to 2003, while the rate for women aged 35-39years rose 6 percent.
- The teen birth rate fell for the 12th straight year, from 43.0 births per 1,000 teens aged 15-19 years in 2002 to 41.7 in 2003.
- Birth rates for women aged 20-24years decreased slightly by 1 percent in 2003, while for women aged 25-29 years the rates increased slightly (by 2 percent).
- The proportion of births to unmarried women increased from 34 percent in 2002 to 34.6 percent in 2003, while the birth rate for unmarried women grew 3 percent over the same period. Meanwhile, births to unmarried teenagers declined for the fifth straight year, though the decline was slight.
The report includes other important health information, such as:
- The percent of mothers who smoked during pregnancy decreased from 11.4 percent in 2002 to 11.0 in 2003.

- The cesarean delivery rate rose for the seventh straight year. Preliminary 2003 data show that 27.6 percent of all births were cesarean deliveries, a marked 6-percent increase from 2002.
- The percent of babies born preterm (less than 37 weeks of gestation) rose from 12.1 in 2002 to 12.3 in 2003, continuing its steady increase since the mid-1990s.
- The percent of babies born at low birthweight (under 2,500 grams) rose from 7.8 percent in 2002 to 7.9 percent in 2003. Low birthweight has gradually increased since the mid-1980s.
