Experts think that there is probably a shift in attitudes occurring, where women are choosing to delay having children - particularly as assisted reproductive technology is ever improving - or simply deciding to have fewer.
Birth rates fell for almost all age groups of women younger than 40 in 2017, sending overall fertility rates to a record low, USA health officials reported Thursday.
The 2017 provisional estimate of fertility for the entire US indicates about 3.85 million births in 2017 and a total fertility rate of about 1.76 births per women. The general fertility rate was 60.2 births per 1,000 women aged 15 to 44 years, which marked a record low, down 3 percent from 2016. "The United States is experiencing its lowest birth rate in 30 years". Even between 2016 and 2017 the rate has dropped 7 percent, but from 1990 this figure has come crashing down by an incredible 70 percent.
For the third year in a row, the preterm birth rate increased to 9.93 percent.
The numbers seem to correspond with what the Census Bureau and others have been predicting for years: that America's population growth will increasingly depend on immigrants, after decades in which the USA enjoyed a relatively high fertility rate when compared to other developed countries. In fact, the only age group that saw an increase in birth rates during 2017 was those in their 40's.

Wheeler is 0-3 with a 9.57 ERA in three starts at Citi Field this season and 8-18 with a 5.31 ERA in 33 career starts at home. He still has great stuff, however, and has struck out 56 batters this season over 43 innings and he's only walked 13 batters.
"Education and access to contraception are big factors in decreasing teen pregnancies", Wu noted. In this age group, there were 11.6 births per 1,000 women, up 2 percent from 2016.
While the number of births nudged up in 2014, it's fallen for three consecutive years.

The 2017 numbers also represent a 10-year fall from 2007, when the US finally broke its post-World War Baby Boom record, with more than 4.3 million births.
