Top 10 Countries That Most US Immigrants Come From

Today, more than 40 million people in the United States were born in another nation, accounting for roughly one-fifth of all global migrants. The immigrant population is likewise extraordinarily diverse, with people from nearly every country on the planet living in the United States.

In 2018, the foreign-born population in the United States reached a record high of 44.8 million. Since 1965, when US immigration rules replaced a national quota system, the number of immigrants in the United States has more than doubled. Immigrants now account for 13.7% of the US population, nearly double their percentage (4.8%) in 1970. However, today’s immigrant proportion remains lower than the record 14.8% share in 1890, when 9.2 million immigrants resided in the United States.

One in every seven residents in the United States is an immigrant, and one in every eight is a native-born citizen with at least one immigrant parent.

In 2019, 44.9 million immigrants (foreign-born individuals) made about 14% of the national population.

The United States had 22.0 million women, 20.4 million men, and 2.5 million immigrant children.

In 2019, 38.3 million persons in the United States (12 percent of the population) were native-born citizens with at least one immigrant parent.

The United States is a country founded and developed by immigrants from all over the world. As a result, it has the highest immigration rate of any country.

As of 2021, more than 45.3 million persons in the United States were foreign-born, accounting for around one-fifth of global migrants. While some come to reconcile with family, others seek employment or flee unsafe situations.

So, why do individuals immigrate to the United States? This picture depicts the many reasons given by new entrants to America in 2021, based on data from the United States Department of State compiled by USAFacts.

Unauthorized immigrants account for over 25% of the foreign-born population in the United States.

According to recent Pew Research Center estimates based on census data adjusted for undercount, the majority of immigrants (77%) are legal residents, while about a quarter are undocumented. In 2017, 45% became naturalized US citizens.

In 2017, 27% of immigrants were permanent residents, while 5% were temporary. Another 23% of total immigrants were undocumented. From 1990 to 2007, the undocumented immigrant population more than tripled, rising from 3.5 million to a record 12.2 million in 2007. By 2017, the number had decreased by 1.7 million, or 14%. In 2017, the United States had 10.5 million undocumented immigrants, accounting for 3.2% of the total population.

The decline in the unauthorized immigrant population is mostly due to a decrease in the number of Mexicans, the single largest group of undocumented immigrants in the United States. Between 2007 and 2017, this group declined by 2 million. Meanwhile, there was an increase in the number of Central Americans and Asians.

Mexicans are the largest group of immigrants living in the United States. The Migration Policy Institute, a neutral organization, says this has been true since 1980. And the route from Mexico to the United States is the world’s largest migration corridor.

However, the total number of Mexican immigrants living in the United States has been declining for more than a decade.
