      **Data Source**

      [How the origins of America’s immigrants have changed since 1850](https://www.pewresearch.org/short-reads/2024/07/22/how-the-origins-of-americas-immigrants-have-changed-since-1850/) (Pew)

      **Tools**

      Adobe Illustrator

      **Theory**

      I call this visualization a “historigraph”. That means it is depicting not just time but “history”. By history, I mean “the complex web of places and individuals interacting over time”. A standard heatmap, which would sort the states in an arbitrary order like alphabetical or year of statehood would only show the data in a reductionistic way, as in you’d only be able to read it on a state-by-state or year-by-year level.

      But for this graphic, I ordered the states spatially. In other words, the closer any two states are on a map, then the closer they will be on the Y axis. That allows regional patterns across space and time to appear more clearly.

      The sheer number of countries means that it was a challenge to make it easy to differentiate colors.

      If you like the historigraph, check out the [**US Elections map**](https://www.reddit.com/r/dataisbeautiful/comments/1bvut82/oc_a_spacetime_map_of_american_presidential/) I posted earlier this year.

      **Content**

      This historigraph depicts the pattern of immigration to America, state by state. Each cell is color coded by country of origin. The dominant nationality immigrating to each state determines the color. This does not account for internal migration. In the spirit of the Thursday-only rule, let’s keep the discussion to the history aspect.

      **Some points of interest**

      * The influx of Russians following the communist takeover of a Russia. They didn’t concentrate in one region but moved to many different areas.
      * The influx of Poles to Illinois (i.e. Chicago) following the Nazi occupation, followed by communist occupation of Poland.
      * Louisiana was the first state to receive mainly Italian immigrants, not New York or New Jersey.
      * Brazilians mainly moved to Massachusetts, likely due to the large Portuguese speaking community there.

      See if you can find other points of interest!

      What if you used flags instead of colors that were very similar and difficult to identify?

      Was there any sort of policy change or world even that happened between 1990 and 2000 to cause the shift?

      Ohh will you look at that! immigration started to be a problem when brown skin immigrants started to be higher. Back in the days, the Irish and Germans were welcomed with open arms. It was never an immigration issue, it’s a skin color issue.

      I don’t see how anyone could possibly have this data going back to the mid-19th century. Also, it should probably start when places actually became states.

      Just looking at Hawaii and I see it’s wrong. It doesn’t show the immigration of white people who make 25% of the population. The white devils been invading Hawaii shores and poisoning the blood of the people for generations…

      I have questions. I grew up with way too many Polish, Italian, Asian, and Middle Eastern people in Michigan for this to be correct.

      i don’t remember running into a lot of Canadians growing up in California during the 1990s

      It’s interesting how demographic influx changes correlate with societal decline.

      national flags would have made more sense for this graph than colors… too many colors = no workie for my ADHD brain.

      Since the actual theme here in r/dataisbeautiful is presentation, I’d say I like this. Not perfect, but a kind of visualization that I haven’t come across before. I’d say that some of the colors are similar and hard to interpret or lookup, so perhaps a subtle number inside the boxes or something or a slight edge marker to distinguish. Not quite sure, but neat visualization and interesting data.

      Very surprised Massachusetts did not have Italian but a lot of Canadians…

      How do you color a state/decade combination?

      Is it the _plurality_ country of origin for that decade, or what?

      Obviously immigration of Canadians to Michigan didn’t stop in the ’90s, nor did immigration of Mexicans to Michigan _start_ in the ’00s. (I personally know counterexamples to both 😄.)

      What’s up with the Chinese moving to Mississippi in the 50’s and no other state showing it anytime since.
