US and Illinois Immigrants by the Numbers
One of every eight Americans is an immigrant (38.5 million out of 307 million total). Of the 38.5 million immigrants, 16.8 million are naturalized US citizens.
Nearly one of every seven Illinois residents is an immigrant (1.74 million out of 12.9 million). Of these, 783,000 are naturalized citizens.
The US immigrant population nearly doubled from 1990 to 2009, from 19.8 million to 38.5 million. The share of the US population who were born abroad rose from 7.9% to 12.5%. Nearly a third (31.6%) of all immigrants to the US arrived in 2000 or after; over half (59.5%) came in 1990 or after.
As of 2009 only one-third of all Illinois immigrants live in the city of Chicago, compared to 49% in 1990. In contrast to previous immigrants, many recent immigrants are bypassing Chicago and moving directly to the suburbs and rural areas.
About 31 million Americans have at least one parent who is foreign-born, including 16.9 million children under 18 and 6.1 million under age 6. Minor children of immigrants make up at least 23.8% of the total population of minor children in the US, and 25.2% of the total population of children under age 6. Between 2000 and 2009, the number of children of immigrants under 6 grew by 37.2 percent nationally, from 4.5 to 6.1 million.
