The New York Times today posted a fascinating interactive map, called Immigration Explorer, which tracks immigration statistics in U.S. Census data from 1880 until the present.
The fascinating thing about this map is that it uses different colors to show significant immigration into New Mexico counties from different parts of the world. Look at the map today and — surprise, surprise — it shows plenty of counties colored red, showing only significant immigration from Mexico and Latin America. But rewind to 1920 and what do we see? Nine counties colored blue and purple, showing an influx from Eastern and Western Europe.
There are no statistics for New Mexico until 1920, after the territory became a state.
Fast forward to 1960, and all of a sudden, Valencia County shows a strong uptick in immigrants from Asia and the Middle East. I’m sure there’s a reason for that… but what is it? Clicking forward through the years, you can see immigration numbers from Europe and Asia disappear as more and more counties reflect immigration from Mexico and Latin America.
Zoom in to look at Los Alamos County in particular. This tiny county, home to Los Alamos National Laboratories, shows strong immigration from Asia and the Middle East (the category includes India) in 2000, but in 1970, immigration there was dominated by Canada.
Fascinating!
