Interactive map showing immigration over the past 130 years

Cool find, although I wish they also percentage-shaded the sub-maps instead of using the bubble system only.

The NYT loves the bubble system. It annoys me.

Anyway, lots of interesting stuff. I echo the need for percentage maps for the individual countries. I did the calculations, though, and Bergen County has the highest percentage of Korean immigrants in the country, although Queens, Orange County and LA County have larger absolute numbers. Middlesex County, NJ has by far the largest Indian immigrant population by percent, although Silicon Valley (Santa Clara County) beats it in absolute numbers.

The perfect example as to why the bubble system fails is looking at Cuban immigration from 1960 to presently. The largest bubble is so large that it envelopes several other bubbles and you can't see which county it belongs to. It just creates clutter.

You can reduce the average bubble size with the slider on the right. That helps when combined with zooming in. Still a problem for places with small counties, especially the NYC area (ironic, considering it's the NYT).

The patterns for Swedish immigration are... odd. Tons of Swedes in southeastern MN in 1880, but they all disappear by 1890. Weird.

Could they have been recording Norwegians as Swedes?

Hmmm... very possible. They don't have separate data for Norway in 1880, which makes it looks more likely. Sweden-Norway broke up in 1905, though.
