A new U.S. Census Bureaunotes that the population of foreign-born people living in the United States has reached 40 million, an all-time high.
That figure—from the 2010 American Community Survey—accounts for about 13 percent of the nation’s total population of 312 million people. That is the largest share of the population since 1910, when foreign-born residents comprised 14.7 percent of the overall population.
About one-third of those foreign-born residents has entered the U.S. since 2000.
Foreign-born residents live in all 50 states and the District of Columbia, but more than a quarter are in California.
