From Pew:
The number of unauthorized immigrants living in the United States in 2015 fell below the total at the end of the Great Recession for the first time, with Mexicans continuing to represent a declining share of this population, according to new Pew Research Center estimates based on government data.
There were 11 m.illion unauthorized immigrants living in the U.S. in 2015, a small but statistically significant decline from the Center’s estimate of 11.3 million for 2009, the last year of the Great Recession. The Center’s preliminary estimate of the unauthorized immigrant population in 2016 is 11.3 million, which is statistically no different from the 2009 or 2015 estimates and comes from a different data source with a smaller sample size and a larger margin of error. This more recent preliminary data for 2016 are inconclusive as to whether the total unauthorized immigrant population continued to decrease, held steady or increased.
