Why Is This Important?

Nonmarital births are at higher risk of having adverse birth outcomes such as low birthweight, preterm birth, and infant mortality than are children born to married women.[https://www.cdc.gov/nchs/data/nvsr/nvsr48/nvs48_16.pdf ^1^] Children born to single mothers typically have more limited social and financial resources.[https://www.cdc.gov/nchs/data/misc/wedlock.pdf ^2^]

How Are We Doing?

The proportion of births to unmarried New Jersey mothers had been steadily increasing for several decades but peaked around 2012 and has been generally declining since then. The rates among Blacks and Hispanics are more than triple the rate among Whites, and the White rate is nearly 4 times the rate among Asians. Among those aged 25-44, the proportion of births to unmarried women in 2020 was double the rate in 1990. The share of births to unmarried mothers ranges from 15.3% in Morris to 62.8% in Cumberland County.

How Do We Compare With the U.S.?

Since 1985, the proportion of births to unmarried women among New Jersey residents has been below that of the nation as a whole. Currently, the rate is 20% lower in New Jersey than in the U.S. as a whole.
