Fact check: How does the age of majority in European countries differ from the US?

Checked on October 26, 2025

Executive Summary

The age of majority in most European countries is 18, with notable exceptions and special rules such as Scotland’s de facto adult status at 16 and instances where marriage confers adult legal capacity; the EU context is also seeing active debate about a separate “digital majority” for online services [1] [2]. The United States generally sets the civil age of majority at 18 in most states, but legal adulthood for specific activities—voting, drinking, and certain contractual capacities—can differ by federal or state law, creating a fragmented patchwork compared with Europe’s more uniform statutory majority [1] [3].

1. Why Europe Looks More Uniform Than It Seems — A Closer Read of the 18-Year Rule

Most European countries have codified 18 as the age of majority, creating a baseline legal adulthood for civil and contractual rights across member states, which simplifies cross-border expectations for citizenship, travel, and EU-wide legal frameworks [1]. However, uniformity masks variation: Scotland’s separate legal traditions mean certain capacities at 16 are recognized domestically, and some jurisdictions restore full capacity to married minors or under specific emancipation rules. The practical effect is that while a headline “18” is common, operational exceptions produce important differences for rights such as marriage, property, and consent [1].

2. The United States’ Patchwork: 18 on Paper, Many Ages in Practice

In the United States the age of majority is widely 18, but federalism produces divergence for age-specific rights—most notably the federal voting age of 18 established by the 26th Amendment, juxtaposed with a nationwide legal drinking age of 21, and variable state rules for driving, marriage, and emancipation [1] [3]. The consequence is a system where the core civil marker of adulthood exists, yet functional adulthood for day-to-day activities depends on the specific legal arena, creating complexity for young people and for comparisons with European norms that treat adulthood more holistically.

3. Digital Majority: A New Frontier Where Law and Platform Rules Clash

Recent proposals and industry moves signal a new layer: the “digital majority” concept, where online access to social media and services would require parental consent under a defined age—European debate has centered on a potential 16-year digital minimum unless parents opt in, and platforms like Meta have pushed for an EU-wide rule and proposed teen account features [4] [2] [3]. This emerging standard does not replace civil legal majority but creates a parallel age threshold tied to platform safety and privacy rules, illustrating how technological regulation can carve out distinct age regimes separate from statutory adulthood [4] [2].

4. How Marriage and Special Statuses Produce Hidden Adultities

Across both Europe and the US, marriage and emancipation can grant adult legal capacity before the statutory majority; several European jurisdictions and US states allow married minors to enter contracts or gain parental rights that otherwise align with adult status [1] [3]. These mechanisms mean that chronological age is not the sole determinant of legal power: social institutions and remedial laws can accelerate adulthood, complicating simple country-by-country tallies and requiring analysis of family law, consent laws, and emancipation procedures to understand real-world legal capacities.

5. Policy Debates Reveal Competing Agendas — Protection versus Autonomy

The push for a digital minimum age has split stakeholders: public authorities and child-rights advocates prioritize protection from harmful content and data exploitation, while some tech firms argue for harmonized rules and parental consent frameworks to maintain platform access [2] [4] [3]. Each position reflects an agenda—regulatory precaution versus operational consistency—and both shape how societies reconceive adulthood in the digital age. The political context therefore influences whether age rules emphasize liberty for young people or safeguards imposed by state and platform actors [2] [3].

6. Practical Consequences for Young People Moving Between Jurisdictions

For cross-border travel, migration, or online life, the coexistence of a civil age of majority (usually 18) with differing digital, drinking, driving, and marriage ages creates real legal friction: a young adult may be fully autonomous in one country yet restricted by platform rules or criminal law in another. This fragmentation matters for education, employment, and parental responsibilities, and underlines why headline ages (like 16, 18, 21) are insufficient alone to predict rights and obligations without consulting the specific legal domain and jurisdictional rule [1] [3] [2].

7. Bottom Line: Similar Labels, Different Rules — What to Watch Next

In sum, Europe and the US largely share 18 as the civil age of majority, but the lived experience of legal adulthood differs because of exceptions (Scotland, married minors), sector-specific ages (drinking, driving), and the rising digital-majority debate that could create new cross-border norms for online participation. Stakeholders should monitor EU legislative proposals and platform policies through 2025, as these will shape whether a separate digital threshold of 16 or similar ages becomes a durable international standard [1] [2] [4].
