In December, the Census Bureau announced that the U.S. population had grown by nearly 1% in the year ended July 1st, 2024, marking the strongest annual gain since 2001[1]. Given this, it seems strange to be already talking about slowing population growth. However, the reality is that the gap between births and deaths is continuing to shrink, with almost all of our recent population growth coming from immigration. Going forward, if immigration is dramatically curtailed, overall population growth could turn negative by the middle of the next decade while the working-age population would immediately start to contract.
