(CNN) - After publishing a report Tuesday on the record low teen birth rate, the National Center for Health Statistics is releasing more numbers on babies in America.
Gladys Martinez and her colleagues at the NCHS have written a report on the fertility of men and women aged 15 to 44 in the U.S. based on numbers from the National Survey of Family Growth that was taken between 2006 and 2010. The survey collected data from more than 22,000 face-to-face interviews.
A few interesting tidbits emerged from the report. The NCHS survey found that a greater proportion of births to unmarried couples are happening in households with cohabitating partners than in years past.
