“In 2020, the general fertility rate in the US hit its lowest level on record, and provisional data for the first six months of 2021 showed a 2 percent decline in the number of births compared to the same time period in the previous year.
And what’s happening in the US is taking place in much of the rest of the world, as people are slower to marry and slower to have children.
That trend has helped contribute to what will be one of the dominant themes of the 21st century: the slowdown of population growth, especially in developed countries, and the eventual shrinking of the number of human beings on the planet.”
