This is not the first U.S. decline in 18-year-olds. Federal tables show the number of 18-year-olds fell in the late 1980s and early 1990s.

Full reasoning

An official National Center for Education Statistics table, using U.S. Census Bureau population estimates, shows that the U.S. already had a national decline in the number of 18-year-olds decades ago.

In that table, the count of 18-year-olds was:

  • 3.888 million on July 1, 1989
  • 3.607 million on July 1, 1990
  • 3.397 million on July 1, 1991
  • 3.332 million on July 1, 1992

So the country has been through a decline in 18-year-olds before. That means calling the current moment the "first time ever in US" is factually incorrect.

The same table explicitly lists these figures as coming from U.S. Department of Commerce, Bureau of the Census population reports and national population estimates.
