The US Census Bureau's American Community Survey asks millions of Americans every year several questions about their economic, social, and demographic situations. One of those questions asks respondents to report their families' ancestries, from Italian to German to Mexican.

Using that self-reported ancestry data from the Minnesota Population Center's 2016 American Community Survey Integrated Public Use Microdata Series, we were able to find the most commonly self-reported ancestries in each state. In Connecticut, the most common ancestry found is Italian. In southern Connecticut, New Haven has one of the biggest Italian populations, and the pizza to prove it. The second most common is Irish followed by Puerto Rican.
