The Census Bureau said Thursday there are also marked differences depending on the region of origin. While households of people originating in Latin America, Africa, Oceania and Asia were more likely than the native-born to have children under 18 at home, households from Canada and Europe were less likely.
Officials said 13 percent of the U.S. population in 2010 was born somewhere else, about 40 million people. More than half, 53 percent, of foreign-born residents were from Latin America and the Caribbean, followed by 28 percent from Asia, 12 percent Europe and 4 percent Africa.
More than half, 62 percent, of the foreign-born had been in the United States for 20 years or less in 2010. More than three-quarters of Africans had come to the United States since 1990 and more than half had arrived after 2000.
While 44 percent of foreign-born residents had become U.S. citizens, the percentages were highest for Europeans at 62 percent and Asians, 58 percent.
One-quarter of the foreign-born lived in California, accounting for 27 percent of the state's population. Eleven percent lived in New York, 10 percent in Texas and 9 percent in Florida.
