- Americans come from a wide variety of ancestries.
- Using data from the US Census Bureau’s American Community Survey, we found how common various ancestries are in all 50 states.
- For instance, Irish ancestry is most concentrated in the Northeast, while Mexican and Mexican-American ancestry is most common in the states that share a border with Mexico.
Americans come from all over the world, and American families have countless stories about their origins.
The Census Bureau’s American Community Survey asks several questions about residents’ economic, social, and demographic characteristics and situations. One of the questions on the survey asks respondents to report their families’ ancestries.
Using individual-level data from the Minnesota Population Center’s Integrated Public Use Microdata Series for the 2017 American Community Survey, we found the total number of respondents in each state reporting various ancestries as either their first or second response to that question.
About 83% of respondents listed at least one ancestry. The following maps show the percentage of those who gave at least one answer that said they had a particular ancestry for 17 of the most common ancestries in the US.
