Yesterday, the Supreme Court voted 6–3 to uphold birthright citizenship. That ruling is on every cable channel this morning.

But there’s a number behind that ruling that almost nobody is talking about.

If you were born in the 1960s or earlier, you grew up in an America where nearly everyone around you was born here. Your schools, your churches, your factory floor — 95% native-born. In 1970, the foreign-born share of the population was just 4.7%. About 1 in every 21 people.

Then came a 55-year climb. In January 2025 the share hit 15.8% — 53.3 million people, roughly 1 in 6. That’s the highest share ever recorded in American history, higher than the great European wave of the 1890s that topped out at 14.8%.

Look at the chart. You can see the whole arc. The share peaked in 1890… fell for 80 straight years as Congress tightened the gates… bottomed out in 1970… then the 1965 Immigration Act rewrote the rules and the curve reversed. It didn’t stop climbing until early last year.

Since then, it’s finally started to bend the other way. ICE reported 442,637 deportations in fiscal 2025. Fiscal 2026, which closes in three months, is on pace for roughly 460,000 — the highest full-year total in more than a decade. The Center for Immigration Studies estimates the foreign-born population has fallen by roughly 2 million from the January 2025 peak. The share is now near 15%.

But look at that drop again. Even after the fastest 18-month decline in the survey’s history, we’re still higher than the 1890 record. And yesterday’s ruling guarantees that every child born on American soil during this wave is a citizen. That single fact will shape wages, housing demand, Social Security math, and elections for a generation.

The legal arguments will fill cable news for weeks. But the demographic shift is already here. It’s going to shape your taxes, your Medicare, and your grandkids’ job market for a generation. Worth a conversation at the dinner table tonight. Not next week. Tonight.
