How Are We Doing?

The percentage of births to unmarried mothers (nonmarital birth rate) had been steadily increasing for several decades but peaked around 2010 and has been slowly declining since then. The largest differences between 1990 and 2015 were among White (61% increase) and Hispanic mothers (47%), while differences among Black (+4%) and Asian (-7%) mothers were more modest. The nonmarital birth rate more than doubled among those aged 25-44. Although the largest increase was seen among foreign-born mothers, infants born to mothers native to U.S. territories (predominantly Puerto Rico) still have the highest nonmarital birth rate. Nonmarital birth rates range from 15% in Morris to 61% in Cumberland County.

How Do We Compare With the U.S.?

Since 1985, the nonmarital birth rate among New Jersey residents has been below that of the nation as a whole. Currently, the rate is 18% lower in New Jersey than in the U.S. as a whole.
