The provisional count of births in the United States for the 12-month period ending June 2013 was 3,941,000, which was not significantly different from the 3,944,000 births (provisional count) for the 12-month period ending June 2012 (1). The number of births has declined from the historic high of 4,316,233 in 2007. However, the decline has slowed from 2010 through 2011, and the number was essentially unchanged from 2011 through 2012 (Figure ) (2,3).

The provisional fertility rate in the United States for the 12-month period ending June 2013 was 62.7 births per 1,000 women aged 15–44, which was down slightly (less than 1%) from 63.0 births per 1,000 women aged 15–44 for the 12-month period ending June 2012 (1). The fertility rate has also declined from the recent high of 69.3 in 2007. However, the decline has slowed from 2010 through 2011 and further again from 2011 through 2012 (Figure ) (2,3).

Data sources and methods

Provisional counts of births for 2013 are based on a combination of counts of events provided by each reporting area and registered vital events processed into National Center for Health Statistics (NCHS) data files for the 12 months ending with the specified month (i.e., June 2013). For further information about the provisional counts, see Births, Marriages, Divorces, and Deaths: Provisional Data for 2009 (4). Preliminary birth data for 2012 are based on nearly 100% of 2012 births. Records of the states with less than 100% of records are weighted to independent control counts of all births received in state vital statistics offices in 2012 (2). Final birth data for 2011 and earlier years are based on complete files of 100% of the births registered in state vital statistics offices and reported to NCHS (3).
