No, morons online think there are 50 different countries. That’s not true at all. Different states aren’t really that different.

Here’s how it works. There’s a sort of “generic American” culture that’s mostly what you see on TV and in movies. Then there are a few variations on that. Here’s a list of those variations;

Black culture. This is the most distinct, most specifically American variant of American culture. It’s not monolithic, but there are a few unique elements of Black American culture that are specific to black people. It’s unique enough that I’d say it definitely counts as its own culture.

Regional variations. Certain regions have more distinct cultures, same as anywhere. A place with very little local identity like say the suburbs outside of a small city in Washington state will look a lot closer to the “generic American” variety of American culture than somewhere with deeper local culture like say towns in Louisiana that still speak cajun French. These differences as rapidly dying out though and everywhere is starting to look more or less the same. Regions with strong identities include the Deep South, New England, NYC and its suburbs, and parts of the midwest like Chicago.

There is also the related urban/rural divide, with much of the “rural” population really being suburban people cosplaying as farmers with oversized trucks.

Native Americans obviously have their own cultures and languages and often land that is legally recognized as sovereign territory. There is also kind of an overarching Indian American culture that’s ties them together.

Immigrant groups. Like any place with immigrants, the US has neighbors with large populations of a specific immigrant group, often creating their own distinct communities.

Hispanic America is its cultural group as well, being comprised of both immigrants and hispanic Americans who lived in what was New Spain/Mexico then became the US after the Mexican American war. There is a bit of a divide where in the west most hispanic Americans are from Mexico and in the east most are from the Caribbean and Central America.
