The fertility rate in the United States has fallen below replacement levels for the first time in more than a decade, as the number of women entering the workforce continues to decline.
The fertility of American women has been declining for the past five years, according to a report by the Pew Research Center.
The rate of birth in the U.S. dropped by more than 1.5 percentage points last year, according the National Center for Health Statistics.
This is the first drop since the recession ended in 2009.
The number of births in the country dropped by 1.8 million, according a report from the University of California, Davis.
The national birth rate was about 2.4 births per 1,000 women ages 15 to 44, according Census Bureau figures.
That’s down from 3.7 births per thousand women in 2011.
The birth rate has been falling since 2012, according one of the most recent surveys.
In April, a Pew Research poll found that the rate of births among women aged 40 to 44 had fallen for the third straight year, to a record low of 1.6 births per million women.
A recent study from the National Women’s Law Center found that in 2012, the number was 1.7 million, up from 1.4 million in 2011 and 2.2 million in 2010.
But, the National Health Interview Survey found that fertility rates among women ages 45 to 54 were rising.
In the past year, the rate rose by 2.5 points to 2.9 births per 100,000.
The decline in fertility among women between ages 55 and 64 was also on the rise, with a 1.9-point increase in the rate to 2 births per 10,000 females.
This year, in addition to a decrease in births, the birth rate for women in this age group fell by 1 point to 2,092 births per one million women, the report said.
A number of factors are contributing to the declining fertility rate.
In some parts of the country, such as the Midwest and the South, the fertility rate has remained steady.
But in some states, like the Northeast and the West, it’s falling.
Another factor that’s driving the decline in birth rates is that the number in the workforce has grown significantly, which has contributed to the increase in women entering labor force.
The U.M.B.A. says women in their 40s and 50s are entering the labor market at a much higher rate than in previous years, with their rates increasing from 6.1 births per 1000 women in 2007 to 12.5 births per 10000 in 2014.
The growth in the number entering the workplace has also led to an increase in childbearing.
According to a study from Pew, women are more likely to have children than men and have fewer children per child than in the past.
This means that there are fewer men working than there were years ago.
The Pew report found that among women who are working and those who are not, the percentage of women ages 20 to 34 working increased from 28 percent in 2008 to 37 percent in 2014, and the percentage who are employed declined from 33 percent to 25 percent.
Women are also more likely than men to be working part-time, and they are more frequently working at lower pay.
