Most of Europe Does Not Grant Citizenship by Birth Alone. Here Is the Map

Somewhere in a cable-news green room, a panelist is about to tell you that automatic citizenship for anyone born on the soil is "the global standard." It is a confident sentence. It is also a sentence that collapses the moment you open an atlas and a nationality statute at the same time.

Let me give you the map. Then let me tell you what the map does and does not prove, because both halves matter, and because honest argument beats a good talking point every time.

Two terms, defined

Every serious conversation about citizenship starts with two Latin phrases, and the whole debate lives inside them.

Jus soli means "right of the soil." You are a citizen because you were born within the territory. Jus sanguinis means "right of blood." You are a citizen because your parent was one. Almost every country uses some mix of the two. The question is which one is the default and what conditions are attached to the other.

Here is the claim I will defend in this post, in three parts:

1. Unconditional jus soli, meaning birth on the territory is enough whatever the parents' status, is common in the Americas and uncommon in Europe, Asia and the developed world generally.
2. Several democracies that once had it deliberately ended it, through ordinary legislation or a public vote, and they gave reasons that were neither exotic nor sinister.
3. None of this settles the American question, because the American rule is written in a constitutional amendment, and an amendment is read by its text and its history, not by what Paris or Canberra decided.

That third point is the one both sides tend to forget, and I will come back to it. First, the tour.

The table

Here are the seven systems your plan row asked for, stated as plainly as the statutes allow. Check each against the national legislation if you are building anything on it, because nationality laws get amended.

Read the last two rows twice. Canada and Mexico are both on the list because the honest version of this argument has to include the neighbors who still use the old rule. If I handed you a table with only the countries that proved my point, I would be doing exactly what I am accusing the panelist of doing.

The United Kingdom: from soil to settled parents

The British story is the cleanest example of a country that held the old rule and then changed it on purpose.

For centuries, the common law treated anyone born in the King's dominions as a subject of the Crown. That was jus soli in its purest form, and it is where the American common-law inheritance comes from. In 1981 Parliament passed the British Nationality Act, which took effect on January 1, 1983. Under it, a child born in the United Kingdom is a British citizen automatically only if at least one parent is a British citizen or is "settled," which in practice means holds permanent residence.

The logic is easy to see. A state that decides who may settle will sooner or later ask why the child of someone who was never permitted to settle should be a citizen from the first breath. Parliament answered that question in statute in 1981, and the country has lived under that answer for more than four decades.

Notice what the British did not do. They did not strip anyone of a citizenship they already held. They changed the rule going forward. Keep that distinction in your pocket; it matters for every country below.

Ireland: a referendum, not a decree

Ireland's change is the most instructive, because the people themselves made it.

Under the 1998 settlement that accompanied the Good Friday Agreement, the Irish constitution had been amended to recognize the right of everyone born on the island of Ireland to be part of the Irish nation. That wording was written with Northern Ireland in mind. Over the following years it came to be read as creating an unconditional birth rule for anyone born on the island, whatever their parents' status, and the government moved to change it. The European Court of Justice's Chen ruling that October, about a Chinese mother who had traveled to Northern Ireland to give birth so that her daughter would hold an Irish and thus European Union passport, came after the vote, but it showed what was at stake.

The government put a constitutional amendment to the voters in June 2004. The Irish people approved it by a wide margin. The resulting Irish Nationality and Citizenship Act of 2004 ties birth citizenship to a parent's connection: an Irish parent, a British parent with no time limit on their stay, or a parent who has been resident on the island for three of the four years before the birth.

Think about the democratic point here. A nation with a long, proud tradition of being a place people left, and a deep moral memory of emigration, still concluded that citizenship should follow a parent's lawful connection to the country. They did it by asking the voters, in a vote, and the voters said yes. That is not a story about cruelty. It is a story about a political community deciding for itself who belongs.

Australia: 1986

Australia is a nation of immigrants by any honest definition, and it is a good test for the lazy claim that ending automatic birth citizenship is a form of xenophobia.

Before 1986, a child born in Australia was an Australian citizen by birth. The Australian Citizenship Amendment Act 1986, in force from August 20, 1986, changed the rule: a child born in Australia is a citizen at birth if at least one parent is an Australian citizen or a permanent resident. A child born to parents without that status is not automatically a citizen, but can acquire citizenship after living in Australia for ten years.

Australia kept a large legal immigration program afterward. It still takes in people from every continent. What it stopped doing was treating birth on the soil, taken alone, as the whole of the test. The ten-year provision is worth noticing, too. It shows a country that wanted to connect citizenship to a real stake in the place, not to an accident of the delivery room.

France and Germany: two different roads

France and Germany give you two lessons for the price of one, because they started from opposite ends and ended up in similar places.

France has an old tradition of what scholars call "double jus soli." A child born in France to a foreign parent who was himself or herself born in France is French at birth. A child born in France to two foreign-born parents is not automatically French, but can become French at eighteen if resident in France with a record of residence since the age of eleven, and can sometimes claim it earlier. French politics has gone back and forth on these details over the decades, tightening and loosening the residence conditions. What has not changed is the principle that citizenship follows a durable connection, not a single moment of birth.

Germany went the other direction. For most of the twentieth century its law was almost purely one of blood: German citizenship came from a German parent. A reform that took effect on January 1, 2000 added a limited birth rule: a child born in Germany to foreign parents acquires German citizenship at birth if at least one parent has lived legally in Germany for a set number of years and holds a settled residence status. The point to take away is that even when Germany added soil to blood, it attached residence conditions to the soil.

So here is the pattern in Europe. Where the old rule was blood, soil got added with conditions. Where the old rule was soil, conditions got added to it. Nobody in this group arrived at "the baby of a visitor is a citizen on arrival." That is the conclusion a careful observer draws, and it is as far as the foreign evidence goes.

Canada and Mexico: the neighbors with the old rule

Now the other side of the ledger, and I will state it as fairly as its defenders would.

Canada grants citizenship to nearly everyone born on its soil. The exception is children of foreign diplomats and similar officials, whose parents are not subject to the ordinary jurisdiction of the country. Canada's rule is unconditional in the way the American rule is generally understood to be, and Canada is as modern, as wealthy and as law-abiding as any country on this list. A Canadian legislator who wanted to change the rule would find no constitutional barrier of the American kind, but would face a very different political culture, and so far none has.

Mexico's rule is stronger still, because it sits in the constitution. Article 30 lists the ways to be Mexican by birth, and the first is to be born on Mexican territory, whatever the nationality of the parents. If you want a single image of how unremarkable the old rule is in this hemisphere, that is it.

And that is the real shape of the map. The Western Hemisphere is the stronghold of unconditional birth citizenship. Much of the rest of the developed world is not. The reasons are historical: the New World was settled by people who wanted newcomers to become members, and its law was written in the age of settlement. Old Europe was built on nations with ancestral claims to a particular ground and a particular people, and its law followed.

The steelman: "So what?"

Now the strongest case against the point I am making, put in words its defenders would accept.

The objector says: Foreign practice is irrelevant. Brazil and Canada and Mexico have the old rule. Maybe Britain and Australia were wrong to drop it. Birthright citizenship has real virtues. It is simple, it prevents the creation of a hereditary class of people who live their whole lives in a country without belonging to it, and it rules out the nightmare of stateless children. The countries that dropped it have had to build elaborate rules about parents' status, and those rules require paperwork that fails vulnerable families. A child cannot choose where she is born, and she should not be punished for her parents' choices.

That is a serious argument, and I do not want to dismiss it. The statelessness point in particular is real: any country that attaches conditions to birth must have a safety net so a child does not end up with no nationality anywhere, and most of the countries on the list have one. The simplicity point is real too. A rule you can administer at a hospital bed is a rule with administrative virtues.

Here is my answer, in order.

1. The foreign evidence answers one claim, not all of them. It refutes the statement that unconditional birthright citizenship is "the global standard." It does not prove that the American rule is wrong. Those are different claims and an honest debater keeps them apart.
2. Conditions are not cruelty. The systems that attach conditions provide for stateless children, and they do not strip existing citizens of anything. The child of settled residents is a citizen in every country in the table with conditions. The child of a visitor, or of someone present unlawfully, is a citizen of the parent's country under that country's own law, and in most of these systems can become one of the host nation's citizens after a period of real residence.
3. A political community defines its own membership. This is the oldest idea in the book. Locke's account of consent and Burke's account of a nation as an inheritance both treat citizenship as something a community confers, on terms, not something that attaches by gravity. Whatever you think of the policy, the principle that a nation sets terms for membership is not a fringe view; it is the view of most of the world's democracies.
4. The objector's best point is about administration, and administration is a design problem. Birth-record systems and parental-status documentation exist already in every country that has made the change. They cost something. They also prevent a particular kind of abuse, the arranged late-term trip whose only purpose is a passport. Whether the savings exceed the costs is a legitimate debate. It is not a debate about whether a decent country may ask the question.

Why the American question is different

Now the point that governs the rest.

In the United States, the question is not whether it would be wise to have a rule like Britain's or Australia's. It is whether the Constitution already has a rule, and whether Congress or the President can change it without an amendment. The text is the Citizenship Clause of the Fourteenth Amendment, ratified in 1868:

All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.

Everything turns on what the qualifying phrase "subject to the jurisdiction thereof" means. The Supreme Court addressed the clause in United States v. Wong Kim Ark in 1898, holding that a child born in San Francisco to Chinese parents who were lawfully and permanently domiciled in the United States was a citizen. The Court's reasoning rested on the common-law tradition of birth within the allegiance of the sovereign. What the Court did not decide, and what scholars on both sides argue over today, is how far the holding reaches to children of parents who are unlawfully present or only temporarily visiting. You can read that argument from both sides in Wong Kim Ark and the 1898 Birthright Case, Read Fairly From Both Sides and in Subject to the Jurisdiction Thereof, Six Words at the Center of Citizenship.

Notice what this means for the table above. Foreign practice cannot answer a question about what a clause adopted in 1868 means. The Fourteenth Amendment was written by men who had just fought a war over whether a Black American could be a citizen at all, and who were reacting to the Dred Scott decision. The history that matters is the history of that amendment, its debates and its text, not the history of the British Nationality Act.

Which is why I think both sides in this debate sometimes misuse the map. The side that wants to end birthright citizenship by statute or executive action cannot say, "Europe did it, so we can." Europe did it by statute because Europe had no such amendment. The side that defends the current reading cannot say, "everyone does it this way," because that is false. What the map actually does is remove a bad argument from each side and send both back to the text.

If you believe the clause should be read more narrowly than it has been, the Founders gave you a way to say so, and it is not a press release. Article V provides for amendment, and the Constitution's amending process was built for exactly this kind of question. If you believe the current reading is right, then the strength of your position is the strength of the text and of the cases, and you can make that argument without inventing a world consensus that does not exist.

What the map is good for

Let me say what I think a conservative should take from the table, because a map is only useful if it changes a decision.

First, it tells you the policy question is legitimate. Countries with long democratic histories, strong rule of law and large immigrant populations have restricted birth citizenship without becoming tyrannies. If someone calls that idea unthinkable, hand them the Australian statute.

Second, it tells you to be modest about your own claims. A conservative case built on "Europe does it" is a case built on sand, because the American instrument is a constitutional amendment and its meaning is a matter of text and history.

Third, it tells you where the real fight is: in courts, in Congress and, if it comes to that, in state legislatures acting under Article V. That is where a citizen can do something. Reading the clause, understanding the cases and asking your representatives where they stand are all things you can do in an afternoon.

Fourth, and I say this with some warmth, it reminds us that a generous country and a country with rules are not opposites. Australia and Canada take in newcomers at a high rate. The countries with conditions are not the ones that closed their doors; they are the ones that decided membership should follow a real connection. Our own tradition of welcoming people who play by the rules is stronger when the rules mean something. For the shape of that tradition, see One Uniform Rule, How the First Congresses Wrote America's Naturalization Laws, and for the way other nations protect their lines, see How Japan, Denmark, Switzerland and Mexico Guard Their Own Borders.

A short checklist for the next dinner-table argument

You will hear this topic raised sooner or later. Here is a short way to keep your footing.

• If someone says "everyone does it," ask them to name the European country. Then name the United Kingdom, Ireland, Australia, France and Germany and the dates they changed their rules.
• If someone says "Europe proves we must end it," answer that Europe has no Fourteenth Amendment, and that what the clause means is a question for the text and the courts.
• If someone says "this is about cruelty," point out that the countries with conditions have safeguards against statelessness and still run generous immigration programs.
• If someone says "this is about the Constitution and nothing else," agree, and then ask what they think the six words "subject to the jurisdiction thereof" were meant to exclude, because the answer is the whole debate.

The case in brief

1. Unconditional birthright citizenship is the rule in the Americas, with Canada and Mexico as examples, and the exception in most of the developed world.
2. The United Kingdom (1981 Act, in force 1983), Ireland (2004 referendum) and Australia (1986) ended unconditional citizenship by birth, through statute or a vote, with a requirement of a parent's lawful settled status, and France and Germany attach residence conditions as well.
3. Those changes did not strip existing citizens of anything, and they came with safeguards against statelessness.
4. The American question is governed by the Fourteenth Amendment's Citizenship Clause and by Wong Kim Ark, so foreign practice informs the policy debate but cannot decide what the clause means.
5. Anyone who wants a different American rule has a lawful route, an amendment or a Supreme Court reading of the text, and anyone who defends the current rule should defend it from the text, not from a world consensus that does not exist.

What you can do: read the Citizenship Clause in the Fourteenth Amendment on the Constitution page, then ask your representatives, through the my-representatives page, whether they support a statute or an amendment on birthright citizenship, and why.
