The unauthorized immigrant population in the United States reached 10.5 million in 2021. That was a modest increase over 2019 but nearly identical to 2017.
Since 2000, the size of the immigrant electorate has nearly doubled. More than 23 million U.S. immigrants will be eligible to vote in the 2020 presidential election.
