How Birthright Citizenship in America Is Changing — And Why It Counts

Only about 33 countries still grant automatic citizenship to anyone born within their borders—and that number continues to decline. The United States is one of the few major nations that still follows this long-standing principle, though it now faces one of its most serious challenges in over a century.

Since 1898, the 14th Amendment has guaranteed citizenship to “all persons born or naturalized in the United States.” This broad interpretation has helped make the U.S. one of the most inclusive countries when it comes to birthright citizenship. However, recent debates—including proposals to limit citizenship to children of citizens or legal residents—have reignited global questions about who qualifies as a member of a nation.

Why it matters: This issue goes beyond constitutional law—it speaks to how countries define belonging, identity, and opportunity in a world shaped by migration, diversity, and economic change.

The Supreme Court could soon weigh in on whether a president has the authority to restrict birthright citizenship through executive action, potentially overturning more than 125 years of legal precedent. Since the 1898 United States v. Wong Kim Ark decision, nearly everyone born on U.S. soil has automatically been recognized as a citizen, regardless of their parents’ legal status.

Around the world, birthright citizenship is becoming less common:

• About 32 countries still follow an automatic system like the U.S.
• Around 156 countries base citizenship primarily on descent
• Roughly 50 countries use a hybrid approach, combining birthplace with residency or ancestry requirements

Experts say this global shift reflects efforts to manage migration, maintain social stability, and respond to political pressures. Still, limiting automatic citizenship could have significant consequences—fewer citizens may lead to a smaller workforce, slower economic growth, and demographic challenges, especially in aging societies.

As countries continue to debate who truly “belongs,” any decision by the U.S. could shape global norms around citizenship, migration, and national identity for decades.
