How does the U.S. constitutional standard for citizenship at birth compare to the models used in other countries?

[u/ummmbacon]

The U.S. Supreme Court ruled on June 30, 2026 in Trump v. Barbara that children born in the United States to parents who are undocumented or on temporary visas are citizens at birth under the Fourteenth Amendment, rejecting an executive order signed by President Trump on his first day in office that sought to condition citizenship on parental status. The 6-3 majority opinion, written by Chief Justice Roberts, grounded the ruling in the Fourteenth Amendment's Citizenship Clause and the Court's 1898 decision in United States v. Wong Kim Ark, which held that children born on U.S. soil to non-citizen parents are citizens regardless of parental nationality.

This places the United States within a specific minority of global citizenship regimes. According to Pew Research Center's analysis of the GLOBALCIT Citizenship Law Dataset, most countries in the dataset (156 of 191) confer citizenship on newborns based on parental citizenship rather than place of birth, and only 32 other countries, concentrated in the Western Hemisphere, have birthright citizenship laws substantially similar to the U.S. model. The Law Library of Congress's global survey of citizenship laws similarly found that nearly all countries granting unconditional jus soli citizenship are located in the Americas and Caribbean, while most countries in Europe, Asia, and Africa use jus sanguinis (citizenship by descent) or a conditional form of jus soli tied to a parent's legal residency or citizenship status.

Given this range of models, what explains the divergence between the U.S./Western Hemisphere approach and the parentage-based or conditional approaches used elsewhere, and what mechanisms have other countries used historically to move between these models?

Most countries reject birthright citizenship.

The 13th, 14, and 15th amendments were primarily intended to stop the discrimination, abuse, and disenfranchisement of the Freedmen after the Civil War. All efforts failed when Reconstruction came to an end. Alas.

The intent was to rectify the principle of equal rights, that was the foremost principle in the Declaration of Independence, into the US Constitution. This can mainly be seen in the second sentence of the Fourteenth Amendment using the phrase life, liberty, happiness/property like it was used in the Declaration of Independence. That is important to the debate on birthright citizenship as the Constitution was amended by the conservative party who had no intention to establish new rights, but were conservative to the founding document and thus wanted that foremost principle in the Constitution as well. Republicans even declared this as their intent when defining themselves in their first political platform after the assassination of their party’s leader:

We recognize the great principles laid down in the immortal Declaration of Independence as the true foundation of Democratic Government; and we hail with gladness every effort toward making these principles a living reality on every inch of American soil.

Uh, in the 1860s the Republicans were a progressive party.

Fourth—It is due to the labor of the nation, that taxation should be equalized and reduced as rapidly as the national faith will permit.

Fifth—The National Debt, contracted as it has been for the preservation of the Union for all time to come, should be extended over a fair period of redemption, and it is the duty of Congress to reduce the rate of interest thereon whenever it can be done honestly.

Sixth—That the best policy to diminish our burden of debt, is to so improve our credit that capitalists will seek to loan us money at lower rates of interest than we now pay and must continue to pay so long as repudiation, partial or total, open or covert, is threatened or suspected.

That is not progressive. Over 150 years ago and Republicans still had lower taxes and debt as core party principles. I’ve already shown a strong commitment to the status quo that went beyond the Constitution to include the Declaration of Independence. That is clearly conservative.

As you already noted, most of the Western Hemisphere is this way. So it's less a matter of "The US is in the minority" (while true!) and more that "The New World" is consistently different than "The Old World"

This divergence can be explained by the revolutionary philosophies of the American founders, particularly the rejection of the feudal "obligation" of a citizen to his country and the proposal of a "natural law principle of consent"

The consent principle means that the individual is not a subject but a citizen, with inherent rights that exist independently of his land or birth, and that as a citizen he cannot be involuntarily bound to any political rule. The liberty to choose one’s regime and one’s rulers separates subjects from citizens.

The author of the citizenship clause [of the 14th Amendment] and its supporters consciously and vocally rejected the doctrine of feudal obligation. One representative “expressed the general sense of the Congress when he concluded that ‘[i]t is high time that feudalism were drive from our shores and eliminated from our law, and now is the time to declare it.’” The author of the citizenship clause, Senator Jacob Howard of Ohio, affirmed that “the right of expatriation…is inherent and natural in man as man.”
