Which Country Descents Are the Most in the USA?

The most common country descents (ancestry/heritage groups) in the United States are German and Mexican , followed closely by groups like Irish , African American (often treated as a U.S.-based heritage), English , and Italian , depending on how you count race vs. ancestry and whether you include Hispanic/Latino origins as “country” descents.

Below is a clear breakdown of the top ancestry groups, with numbers and regional patterns that explain why certain descents dominate in different parts of the country.

Numbers are rounded estimates based on American Community Survey–based analyses (e.g., APM Research Lab 2017 data) and census summaries.

Why German and Mexican Top the List

German Descent

  • Largest single ancestry group : About 13% of Americans claim German heritage, more than any other country-specific descent.
  • Midwest dominance : In states like Wisconsin, North Dakota, South Dakota, Nebraska, Iowa, and Minnesota, more than 30% of residents have German roots.
  • Historical waves of German immigration in the 18th–19th centuries, plus later 20th-century movements, created deep settlement patterns in farming and industrial regions of the Midwest.

Mexican Descent

  • Second-largest : Roughly 12% of Americans have Mexican ties, second only to German.
  • Regional concentration : One-third or more of residents in Texas, California, and New Mexico claim Mexican heritage, with Arizona also very high (about 29%).
  • This reflects both recent immigration and long-established communities in the Southwest, where Mexican culture and population have been central for centuries.

Other Major Country Descents

Irish

  • About 1 in 10 Americans claim Irish ancestry, making it one of the most widespread heritage groups.
  • You are more than twice as likely to meet someone with Irish roots in New Hampshire and Massachusetts compared with the national average.
  • Irish immigration in the 18th–19th centuries, especially during and after the Potato Famine, heavily influenced cities in the Northeast and Mid Atlantic.

English

  • English ancestry is often underreported because many people simply say “American” when asked about ancestry, but estimates still place it around 5% of the population.
  • It is especially common in:
    • The Northeast (historical colonies)
    • Appalachia and parts of the South (early British settlers)
    • Some rural and exurban areas where “American” identity is strong but rooted in early English colonization.

Italian

  • Around 5% of Americans claim Italian heritage.
  • Concentrated in:
    • New York, New Jersey, Massachusetts, Pennsylvania, and other Northeastern states.
  • Large Italian immigration occurred in the late 19th and early 20th centuries, especially to industrial cities.

Scottish and Scots‑Irish (Scots‑Irish / Scotch‑Irish)

  • Combined, Scottish and Scots‑Irish descents make up 4–5% of the U.S. population.
  • Strong presence in:
    • Appalachia
    • The South
    • Parts of the West
  • These groups were关键 in early colonial settlement and later westward movement.

How “African American” Fits In

  • About 1 in 10 Americans have African American heritage.
  • This is often treated as a U.S.-based heritage rather than a single foreign country, though many also trace roots to specific African nations (e.g., Nigeria, Ghana, Ethiopia) or to the Caribbean (Jamaica, Haiti).
  • In Mississippi and Washington, D.C., 35% or more of residents claim African American roots.

Regional Patterns: Where Descents Cluster

  • Midwest : German, Dutch, Polish, Scandinavian (Norwegian, Swedish)
  • Southwest : Mexican, with smaller Filipino, Vietnamese, and other Asian groups in cities
  • Northeast : Irish, Italian, English, Polish, French‑Canadian
  • Southeast : African American, English, Scots‑Irish, with growing Hispanic and Asian communities
  • West : Mexican, Filipino, Chinese, Korean, Vietnamese, Japanese, plus many European groups in specific areas

Important Nuances

  • “American” ancestry : Many people, especially those with long U.S. family histories, report “American” instead of a specific country, which can undercount English, Scottish, and other early descents.
  • Race vs. ancestry : The Census and surveys separate racial categories (White, Black, Asian, etc.) from ancestry/heritage questions, so a person can be, for example, “White” racially but “Mexican” in ancestry.
  • Multiple ancestries : People often have more than one country descent (e.g., German + Irish, Mexican + Salvadoran), so the sum of all groups exceeds 100% of the population.

TL;DR Summary

  • The most common country descents in the U.S. are German and Mexican , each around 12–13% of the population.
  • Irish , English , Italian , and Scottish/Scots‑Irish are also major groups, each several percent of the population.
  • Regional patterns show German dominance in the Midwest, Mexican dominance in the Southwest, and Irish/Italian/English strength in the Northeast and parts of the South.
  • “African American” is a huge heritage group, but it’s U.S.-based rather than tied to a single foreign country.
