This is an amazing chart! I wish you’d used great circles ( https://en.wikipedia.org/wiki/Great_circle ) though.

Thanks. They actually are great circles, generated using arc.js. As they approach the poles the arcs look a little funny, but that is only because it is a cylindrical map projection.

Surprised me how much came from Canada -- has that been a thing, or is Canada a proxy for other countries?

Just anecdata, but my great-great- and great-grandparents emigrated from Serbia via Canada, ultimately ending up in St Paul, at the beginning of WWII.

Didn't know so much Germans came to the US back in the days.

I think most white Americans identify as Irish first and then German second. However, a lot of German heritage was suppressed following anti-German sentiment during WWI and WWII. Edit: it's actually the other way around. German is the most common ancestry for white people in America.

I've long heard that German is the most common ancestry for Americans, but I've always wondered how that was determined. I think they may be counting total immigrants, but not allowing for when the immigrants arrived.

I can readily believe that more immigrants arrived from Germany than from the British Isles, but it's also possible that by the time those German immigrants showed up they were outnumbered by the descendants of the earlier immigrants from the British Isles, perhaps even just immigrants from England itself.

I've never seen any sort of analysis like this, though.

I love new ways to express data. But, as I see animations like this I become a little anxious as I'd like to absorb the information, but if I look too closely in one area then I risk missing a bigger pattern or trend. After watching, I'm convinced that a good old line chart would have been a better representation of the data. Perhaps with some added dynamic behaviour.

My mothers parents were of German heritage. Neither spoke English before entering kindergarten. My grandfather was an engineer in Detroit working on the Liberty aircraft engine that powered the WWI bombers.

He rode the bus to work and it wasn't uncommon for women mostly to come up to him and physically attack him wondering why he wasn't in the armed forces.

I asked my grandmother once why she didn't teach either of her children to speak German. She told me that it was on purpose, they were ashamed and didn't want to make them targets.

They just ask people where their ancestors came from, like on the census. Brits may be undercounted because they've been here so long they don't even know they were British, but also the European population was quite small when they first started to settle here.

The data is a bit skewed, because the biggest flow is in the 19th century, but it shows the borders of the Federal Republic of Germany (1949) not the German Confederation (1815), which included Austria (which itself was much bigger, including Hungary etc.) and Prussia (which was basically where Poland is today). There really was no "Germany" back then, just German speaking states, which fought wars against each other…

Here is the data source: http://metrocosm.com/wp-content/uploads/2016/05/usa-immigrat...

The footnotes on page 11 give a good explanation.

For the most part, Austria, Hungary, and Poland are broken out separately according to their present borders, even for the periods when they weren't separate countries.

I found this surprising as well. However, I'm wondering if there were nearly as many people leaving the U.S. for Canada at the same time. The source data might not be looking at "net" immigration, and for most countries it wouldn't matter, but it might for Canada.
