National origin — in plain language

Plain language

the country, region, or ethnic ancestry where a person or their ancestors were born — a characteristic that cannot legally be used to discriminate against someone in employment, housing, or public accommodations

• country or region of ancestry
• where you or your family came from
• ethnic or ancestral background
• heritage or country of birth

What to watch for

• Non-lawyers often confuse national origin with alienage. National origin refers to where a person or their ancestors came from; alienage refers to their current legal status as a non-citizen. A U.S.-born citizen can experience national origin discrimination even though alienage does not apply to them at all.
• Many readers assume national origin discrimination only affects immigrants or foreign-born individuals. In fact, a third-generation U.S. citizen can be a victim if they are treated unfairly because of their family's ancestry or the ethnic traditions associated with it.
• National origin is often conflated with race or ethnicity, but the legal categories are distinct. Race focuses on perceived physical characteristics; ethnicity on cultural practices; national origin on the specific country or region of birth or ancestry. Treating them as synonyms in translation can narrow the protection the law intends.
• Language-based mistreatment — mocking an accent, requiring English-only without business necessity — can constitute national origin discrimination. Translators who render this term only as 'country of birth' miss the accent and language dimension courts routinely recognize.

Distinguishing from Similar Terms. National origin is routinely listed alongside race, ethnicity, and alienage, but each is a legally distinct concept. Race refers to perceived physical characteristics such as skin color or facial features. Ethnicity encompasses shared cultural practices, language, and traditions. Alienage focuses on current citizenship status — whether someone holds U.S. citizenship or not. National origin targets specifically the country or region of birth or ancestry, independent of race, ethnicity, or citizenship, which is why the four categories often appear together in the same anti-discrimination clause.

What to Watch For.

• Accent and language claims: Courts have held that harassment or adverse employment decisions based on a worker's foreign accent can be actionable as national origin discrimination, making language one of the most fact-intensive aspects of this protection.
• Overlapping categories: A single act of discrimination may involve both national origin and race — for example, targeting someone who appears to be of Arab descent. Documents that list both terms should be read carefully; the two categories can overlap but are not redundant, and a claim may succeed on one even if it fails on the other.

Common Misunderstandings by Non-Lawyers.

• "National origin discrimination only affects immigrants." (No — any person, including a native-born U.S. citizen, can be a victim if they are treated unfairly because of their family's ancestry or ethnic heritage.)
• "National origin and race are the same thing." (No — a person can face national origin discrimination based on their Irish or Guatemalan ancestry without it involving a difference in perceived race. The categories can overlap but are legally separate.)
• "Language rules at work are not a civil rights issue." (No — requiring English-only without a legitimate business reason, or penalizing someone for their accent, can constitute national origin discrimination under federal law.)

Legal definition

National origin refers to the country, region, or ethnic heritage from which a person or their ancestors came. Under U.S. law — particularly Title VII of the Civil Rights Act of 1964, the Fair Housing Act of 1968, and related state statutes — national origin is a protected characteristic: employers, landlords, and providers of public accommodations may not treat someone less favorably because of where they or their family members were born or the ethnic traditions they are associated with. The protection extends to native-born U.S. citizens whose ancestors emigrated generations ago, not only to recent immigrants or foreign nationals.
