A report by the Centers for Disease Control and Prevention (CDC) unveiled that the US birth rate in 2013 reached an all-time low. In 2013, American women gave birth to 3,932,181 babies.

The total number of births declined for the sixth straight year, as 62.5 babies born for every 1,000 women between the ages of 15 and 44. Since 2007, the birth rate has declined by nearly 10%. The peak was seen in 2007 when birth rate was 69.3 per 1,000 women.

The US birth rate in 2013 is a record low since the government started keeping a record of birth rates in 1909. In that year, the birth rate was 126.8. The federal researchers affirmed that the birth rate differed among age groups.

Childbearing is on decline among women under age 30. On the other hand, it continues to increase among women older than 30, which is also the general trend seen over the last 30 years. In 2013, birth rates for women aged 35 and more was at the highest levels seen in approximately five decades.

Last year, the birth rate for women aged 35 and 39 was 49.3 births per 1,000. For women aged 30 and 34, the rate reached 98 births per 1,000. The rates remained unchanged from the last year for women ages 40 to 44, as the birth rate was 10.4 births per 1,000. Whereas, for women aged 45 to 49 the birth rate increased from 0.7 to 0.8 per 1,000.

Good news is that preterm birth rate (a measure for births before 37 weeks of pregnancy) dipped slightly to 11.39%. Except Hawaii, every state recorded a statistically significant decline. Number of births to white and Latino women declined by 1%, but the number remained unchanged for African American women.

From 2009 to 2012, the rate of twin birth has increased by 2% in 2013 to 33.7 per 1,000 women of childbearing age.
