According to a report by Business Insider, a new government report warns that the US birth rate once again fell in 2017 and that Americans still aren't having enough babies to replace the current population. The report, published Thursday by the Centers for Disease Control and Prevention, focused on a measure called total fertility rate, determined by the number of expected births a group of 1,000 women would have during their lifetimes, according to current age-specific birth rates. The report warns that, in order to sustain a population, a country must have a fertility rate of 2,100 births per 1,000 women. However, in 2017, the US rate was down to 1,765.5 per 1,000, or 16% below what's required to maintain a stable population.
