2. Mexicans may no longer be the majority of U.S. unauthorized immigrants.

They made up half of all unauthorized immigrants in 2016, according to the Center’s preliminary estimate, marking the first time in at least a decade that they did not account for a clear majority of this population.

Their numbers (and share of the total) have been declining in recent years: There were 5.6 million Mexican unauthorized immigrants living in the U.S. in 2015 and 2016, down from 6.4 million in 2009.

Meanwhile, the number of unauthorized immigrants from nations other than Mexico has grown since 2009, from 5 million that year to 5.4 million in 2015.

Non-Mexicans numbered 5.7 million in the preliminary 2016 estimate, a total that was not statistically different from 2015.

From 2009 to 2015, the number of unauthorized immigrants from Asia and Central America rose.

Increases in the number from other countries have mostly offset the decline in the number from Mexico (and a relatively small decrease in the number from South America). . .
