This chart shows where U.S. immigrants came from over the past 200 years, measured as a percentage of the U.S. population at the time. Max Galka crunched the numbers and made an interactive map showing the places U.S. immigrants have come from between 1820 and 2013. At Metrocosm, you can adjust the slider to check out different years or just let it play, like this video.
Each dot represents 10,000 people. The 79 million people who immigrated to the U.S. during that period only include those who became permanent legal residents. -via Boing Boing
MrsO came to the US in 1963 when we were married. She got her Visa at the Montreal consulate that December and her green card at the point of entry which was Niagara Falls. She became a US citizen in 2004. Wonder if she shows up in the data.
