The birth rate is very low in almost every country, and unless that changes, civilization will disappear," Musk said in part two of his [Fox News] "Special Report" exclusive interview Friday.

America’s birth rate hit an all-time low in 2023:

The nation’s fertility rate has declined since 1957, when there were 122.9 births per 1,000 women ages 15–44. Data for 2023 puts the current fertility rate at less than half the 1957 rate, 54.5. //

You can't run off to New Zealand or some other place. It's over. So either we strengthen that column and make sure America is strong, and we'll be strong for a long time, or that roof's coming down," he told Baier.
