Numbers, Facts and Trends Shaping Your World
The number of migrants coming to the United States each year, legally and illegally, grew very rapidly starting in the mid-1990s, hit a peak at the end of the decade, and then declined substantially after 2001.
Most of the unauthorized population lives in families, a quarter has at least some college education and illegal workers can be found in many sectors of the US economy.
The undocumented population of the US now numbers nearly 11 million people, including more than 6 million Mexicans according to new estimates based on the most recent official data available.
