(LOS ANGELES TIMES) — The U.S. foreign-born population has risen to its highest level since 1920, with 13% of all those living in the nation in 2010 having been born elsewhere, a new report from the Census Bureau shows.

Forty million of those residing in the U.S. in 2010 were born in other countries, up from 31 million, or 11% of the total, a decade earlier. The foreign-born share of the population dropped between 1920 and 1970, hitting a low of 4.7% in 1970, before rising again for several decades.
