The US foreign-born population reached a record 44.8 million in 2018. Since 1965, when US immigration
laws replaced a national quota system, the number of immigrants living in the US has more than quadrupled.
Immigrants today account for 13.7% of the US population, nearly triple the share (4.8%) in 1970. However,
today’s immigrant share remains below the record 14.8% share in 1890 when 9.2 million immigrants lived in
the US.
Most immigrants (77%) are in the country legally, while almost a quarter are unauthorized, according to new
Pew Research Center estimates based on census data adjusted for undercount. In 2017, 45% were naturalized
US citizens, 27% of immigrants were permanent residents, and 5% were temporary residents in 2017. Another
23% of all immigrants were unauthorized immigrants. From 1990 to 2007, the unauthorized immigrant
population was more than tripled in size – from 3.5 million to a record high of 12.2 million in 2007. By 2017,
that number had declined by 1.7 million, or 14%. There were 10.5 million unauthorized immigrants in the US
in 2017, accounting for 3.2% of the nation’s population. The decline in the unauthorized immigrant population
is due largely to a fall in the number from Mexico – the single largest group of unauthorized immigrants in the
US.
