Recent declines in infant mortality in the United States, 2005-2011.

After a plateau from 2000 through 2005, the U.S. infant mortality rate declined by 12% to a rate of 6.05 in 2011. Provisional infant mortality counts for the first half of 2012 suggest a continued downward trend. Infant mortality declined from 2005 through 2011 for all major racial and ethnic groups, with the most rapid decline among non-Hispanic black women. Among leading causes of death, infant mortality declined for four of the five leading causes. Infant mortality rates declined most rapidly from 2005 through 2010 for selected Southern states; still, rates in 2010 remained higher in the South and Midwest than in other regions. In 2008, the United States ranked 27th in infant mortality rate among Organization for Economic Cooperation and Development countries, and a previous report linked the United States’ relatively unfavorable infant mortality ranking to its higher percentage of preterm births. Despite the recent infant mortality decline, comparing the 2011 U.S. infant mortality rate with the 2008 international rankings would still have the United States ranked 27th.
