American women had fewer children in 2017 than in any other year since 1987, according to a new report released Thursday by the Centers for Disease and Prevention. And the birth rate was the lowest in the US. While there are some positive trends in the report, such as: For example, fewer teen pregnancies, but there are also many worrying, such as more preterm birth.
The report is a preliminary estimate of the births that took place in 2017, based on birth certificates collected by the National Center for Health Statistics. It turned out that in 2017, there were just over 3.85 million births, up 2 percent from 3.94 million in 2016. This is the lowest since 1987 and the third consecutive birthrate in 2014.
 The overall birth rate among women aged 18-44 was about 60 births per 1,000 women, a 3 percent decline from the 2016 rate and a new record low for the country. The rate of premature births also rose for the third year in a row, up to 9.93 percent of all births. And the overall fertility rate was 1.76 children per woman over a lifetime, the lowest since 1976.
"The decline in the [total fertility] rate from 2016 to 2017 was the largest decline since 2010," the report
The overall fertility rate is quite important for the future of a country because it is used to find out if a generation can replace itself. The rate of basic replacement may vary, depending on how many times the children of a country die young, but for most countries, including the US, there are 2.1 children per woman. According to the report, the US has generally been below this starting level since 1971, but is not as bad as other countries such as Singapore and Greece. And we are not near the scenarios Handmaid's Tale or Children of Men .
Further submission of the report revealed differences in the question of who exactly becomes pregnant and who does not.
Black women, for example, had as many children as in 2016, as did Native Hawaiian and Pacific Islander women. Women of every other ethnic or ethnic group saw a birth decline.
The teenage birth rate continued to decline steadily, a decline that began in 1991. Births among women of the most age groups decreased slightly, except for women between 40 and 49 years. The birth rate among women between the ages of 30 and 39 was the first time since 2011, while births among women aged 20 to 29 have been declining slightly for some time.
Why the births are sinking, some experts have blamed everything from declining sperm quality to the damned millennials to start families later or have no children at all.
