Illegal immigration in the United States - Statistics & Facts

Even though the number of illegal immigrants has stabilized in recent years after a period of rapid growth, in 2017, the estimated immigrant population in U.S. was still roughly 10.5 million people. Mexico is the leading country of origin for most unauthorized immigrants.

According to 2017 data from the U.S. Department of Homeland Security, more than 35 thousand people were deported from the U.S. for illegal immigration. Donald Trump's Executive Order 13768, "Enhancing Public Safety in the Interior United States" allows the federal government to more aggressively arrest and deport unauthorized immigrants, regardless of whether they have committed serious crimes.

The overall economic impact of illegal immigration in the U.S. remains largely ambiguous. The total deportation and enforcement costs of removing illegal immigrants from the U.S. were estimated to be between 103.9 to 303.7 billion U.S. dollars in 2015. The United States has also profited from unauthorized immigration. For example, illegal immigrants contribute to taxes. Illegal immigrants in the U.S. paid an estimated seven billion in sales and excise tax, and 3.6 billion U.S. dollars in property tax in 2014

In a 2019 poll, American adults were asked to state their opinion on whether immigrants strengthen the country because of their hard work and talents. About 75 percent of respondents born after 1980 gave a positive answer, while only 44 percent of Americans, born in the time period from 1928 to 1945, agreed with the statement. In a 2019 poll on illegal immigrants being allowed to stay in the U.S. if they fulfill certain criteria, 72 percent of American respondents believed that illegal immigrants should have a way to them to stay legally, if certain requirements are met. Around 27 percent of respondents thought that illegal immigrants should not be allowed to stay in the country legally.
