http://www.cdc.gov/nchs/data/nvsr/nvsr64/nvsr64_01.pdf

[full-text, 68 pages]

 

This report presents detailed data on numbers and characteristics of births in 2013, birth and fertility rates, maternal demographic and health characteristics, place of and attendant at birth, and infant health characteristics. A report of preliminary birth statistics for 2013 presented data on selected topics based on a substantial sample (99.85%) of 2013 births (1). In addition to the tabulations included in this report, more detailed analysis is possible by using the natality public-use file issued each year. The data file may be downloaded from: http://www.cdc.gov/nchs/data_access/Vitalstatsonline.htm (2). The public-use file does not include geographic detail; a file with this

information may be available upon special request (3). Birth data may also be accessed via VitalStats, a data access and analysis tool (4), which includes birth data for 1990–2013, with more than 100 variables including geographic information by state and for counties with populations of 100,000 or more.

for non-Hispanic white and Hispanic women but did not appreciably

change for non-Hispanic black women from 2012 to 2013.

•             The general fertility rate declined 1% in 2013 to 62.5 births per

1,000 women aged 15–44, reaching another record low for the

United States. The total fertility rate also declined 1% in 2013, to

1,857.5 births per 1,000 women.

•             The birth rate for teenagers aged 15–19 declined 10% in 2013

from 2012, to 26.5 births per 1,000 teenagers aged 15–19, another

historic low for the nation; rates declined for teenagers in nearly

all race and Hispanic origin groups.

•             Birth rates also declined for women in their 20s to record lows in

2013. Rates rose for women in their 30s and late 40s in 2013 from

2012; the rate for women in their early 40s was unchanged.

•             The mean age of mother at first birth rose again, to 26.0 years

in 2013, up from 25.8 years in 2012.

•             The birth rate for unmarried women fell for the fifth consecutive

year, to 44.3 per 1,000 unmarried women 15–44 in 2013. The

number of nonmarital births was 1% lower in 2013 (1,595,873)

than in 2012. The percentage of births to unmarried women was

down slightly, to 40.6% in 2013.

2010–2012, declined to 32.7% of all U.S. births in 2013. Declines

in cesarean deliveries were seen at 38, 40, and 41 completed

weeks of gestation in 2013 from 2012 (Figure 1).

•             The preterm birth rate (under 37 weeks) declined again in 2013,

to 11.39%. This rate has been dropping steadily since 2006, for

a total decline of 11%. Pretermbirths in 2013 were down from2012

for non-Hispanic white, non-Hispanic black, and Hispanic births.

•             The 2013 rate of low birthweight (less than 2,500 grams) was

8.02%, essentially unchanged from 2012 but 3% lower than the

2006 high (8.26%).

•             The twin birth rate reached a new high for the nation of 33.7 per

1,000 total births, up 2% from 2012. The triplet and higher-order

multiple birth rate (triplet/+) dropped another 4% in 2013 to 119.5

per 100,000 births and has fallen more than one-third since 1998

(193.5).
