Overall, Mexico has been the largest single source of migrants (12.9 million), followed closely by India (11.8 million) and Russia (11.3 million). In addition, China (8.4 million), Bangladesh (6.5 million) and Ukraine (6.5 million) each have more than 6 million emigrants. Because the United Nations counts both Palestinian refugees and their descendants as migrants, the Palestinian territories have been the source of 5.7 million migrants, by the U.N.’s definition. The United Kingdom, the Philippines and Pakistan round out the Top 10 list of countries of origin for international migrants alive today.

About 110 million migrants, or more than 50% of the global total, have gone to the 10 leading destination countries. With nearly 43 million foreign-born residents, including more than 11 million unauthorized immigrants, the U.S. has more than three times as many international migrants as any other single country.2 Indeed, the U.S. has about as many immigrants as Europe’s top five destinations – Russia (12.3 million), Germany (10.8 million), France (6.7 million), the United Kingdom (6.5 million) and Spain (6.4 million) – combined.3

Levels of Migration, by Religion

Of the seven groups examined in this report, Jews have by far the highest overall level of international migration, in percentage terms. About one-quarter of Jews alive today have left the country in which they were born. Yet because Jews make up only a sliver of the world’s population – roughly 14 million out of a total of 6.9 billion people in 2010 – they represent a small fraction (about 2%) of all international migrants.4

By contrast, only one-in-twenty Christians alive today (5%) have emigrated from their country of birth. But because there are nearly 2.2 billion Christians around the world, that translates to nearly half of the world’s 214 million international migrants. Muslims make up the second-largest share of all migrants – almost 60 million migrants, or a little more than a quarter of all international migrants. Only a small percentage (1-2%) of all Hindus, Buddhists and adherents of other faiths have migrated across borders.

The rest of international migrants (about 19 million) are unaffiliated with any particular religion.

Regional Patterns

The vast majority of people who have emigrated from their native countries in North America, Latin America (including the Caribbean) and Europe are Christians. And, not surprisingly, emigrants from most countries in the Middle East and North Africa overwhelmingly are Muslims. But emigrants from the remaining two regions – Asia-Pacific and sub-Saharan Africa – are more religiously mixed.

A plurality of migrants from Asia and the Pacific are Muslims (37%), but a substantial share are Christians (19%), Hindus (14%), unaffiliated (12%) or Buddhists (10%), reflecting the diverse mix of religions in that vast region. Meanwhile, more than eight-in-ten emigrants from sub-Saharan Africa are either Christians (47%) or Muslims (38%).

In general, the religious affiliation of immigrants to each region is similar to the religious affiliation of emigrants from that region. For example, most migrants who have moved to countries in North America are Christians. This includes large numbers of people who have migrated from Latin America to the United States. The result is that in North America as a whole, Christians make up the vast majority both of emigrants (74%) and of immigrants (72%).

There is more of a disparity between emigrants and immigrants in Europe. While roughly three-quarters of the people who have left European countries are Christians (76%), a substantially lower proportion of people who have moved to European countries are Christians (57%). Both figures include people who have moved within Europe. (For information on immigration to European Countries solely from outside Europe, see the Spotlight on Europe.) About a quarter of all immigrants living in European countries are Muslims (26%), and the rest are mostly unaffiliated (11%).

The Asia-Pacific region also has a notable difference between its largest group of emigrants (Muslims, 37%) and its largest group of immigrants (Christians, 29%). In part, this reflects the number of Muslim emigrants from the region who have moved to Europe and the Middle East. In addition, some countries in the Asia-Pacific region, such as Australia and New Zealand, have large immigrant populations that are predominantly Christian.

Most emigrants from countries in the Middle East and North Africa are Muslims (86%), but the proportion of Muslims among immigrants in the region is substantially lower (69%). This reflects, in part, the movement of laborers to oil-rich countries in the region as well as Jewish migration to Israel.

2 The Pew Hispanic Center has estimated that about 11.2 million unauthorized immigrants were living in the United States in 2010, of which about 6.5 million originated from Mexico. See Jeffrey Passel and D’Vera Cohn, “Unauthorized Immigrant Population: National and State Trends, 2010,” Pew Hispanic Center, Feb. 1, 2011. (return to text)

3 In this report, immigrants to the United States are classified as foreign-born residents if they were born outside of the 50 U.S. states and the District of Columbia. Although people born in some U.S. territories (such as Puerto Rico and Guam) and people born overseas to American citizens receive U.S. citizenship at birth, they are still included among the “foreign-born” in this report, following definitions used by the United Nations Population Division for its demographic estimates. The U.S. Census Bureau, however, does not consider U.S. citizens born abroad (including people born in Puerto Rico and other U.S. territories) to be foreign-born. This explains why the 2010 American Community Survey estimates the number of foreign-born U.S. residents in 2010 at about 40 million, or almost 3 million less than the foreign-born estimate provided by the U.N. Population Division (42.8 million) for the same year. (return to text)

The United States has more immigrants than any other country in the world. Today, more than 40 million people living in the U.S. were born in another country, accounting for about one-fifth of the world’s migrants. The population of immigrants is also very diverse, with just about every country in the world represented among U.S. immigrants.

Pew Research Center regularly publishes statistical portraits of the nation’s foreign-born population, which include historical trends since 1960. Based on these portraits, here are answers to some key questions about the U.S. immigrant population.

How many people in the U.S. are immigrants?

The U.S. foreign-born population reached a record 44.8 million in 2018. Since 1965, when U.S. immigration laws replaced a national quota system, the number of immigrants living in the U.S. has more than quadrupled. Immigrants today account for 13.7% of the U.S. 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 U.S.

What is the legal status of immigrants in the U.S.?

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 U.S. citizens.

Some 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 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 U.S. 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 U.S. Between 2007 and 2017, this group decreased by 2 million. Meanwhile, there was a rise in the number from Central America and Asia. 

Do all lawful immigrants choose to become U.S. citizens?

Not all lawful permanent residents choose to pursue U.S. citizenship. Those who wish to do so may apply after meeting certain requirements, including having lived in the U.S. for five years. In fiscal year 2019, about 800,000 immigrants applied for naturalization. The number of naturalization applications has climbed in recent years, though the annual totals remain below the 1.4 million applications filed in 2007.

Generally, most immigrants eligible for naturalization apply to become citizens. However, Mexican lawful immigrants have the lowest naturalization rate overall. Language and personal barriers, lack of interest and financial barriers are among the top reasons for choosing not to naturalize cited by Mexican-born green card holders, according to a 2015 Pew Research Center survey.

Where do immigrants come from?

Mexico is the top origin country of the U.S. immigrant population. In 2018, roughly 11.2 million immigrants living in the U.S. were from there, accounting for 25% of all U.S. immigrants. The next largest origin groups were those from China (6%), India (6%), the Philippines (4%) and El Salvador (3%).

By region of birth, immigrants from Asia combined accounted for 28% of all immigrants, close to the share of immigrants from Mexico (25%). Other regions make up smaller shares: Europe, Canada and other North America (13%), the Caribbean (10%), Central America (8%), South America (7%), the Middle East and North Africa (4%) and sub-Saharan Africa (5%).

Who is arriving today?

More than 1 million immigrants arrive in the U.S. each year. In 2018, the top country of origin for new immigrants coming into the U.S. was China, with 149,000 people, followed by India (129,000), Mexico (120,000) and the Philippines (46,000).

By race and ethnicity, more Asian immigrants than Hispanic immigrants have arrived in the U.S. in most years since 2009. Immigration from Latin America slowed following the Great Recession, particularly for Mexico, which has seen both decreasing flows into the United States and large flows back to Mexico in recent years.

Asians are projected to become the largest immigrant group in the U.S. by 2055, surpassing Hispanics. Pew Research Center estimates indicate that in 2065, those who identify as Asian will make up some 38% of all immigrants; as Hispanic, 31%; White, 20%; and Black, 9%.

Is the immigrant population growing?

New immigrant arrivals have fallen, mainly due to a decrease in the number of unauthorized immigrants coming to the U.S. The drop in the unauthorized immigrant population can primarily be attributed to more Mexican immigrants leaving the U.S. than coming in. 

Looking forward, immigrants and their descendants are projected to account for 88% of U.S. population growth through 2065, assuming current immigration trends continue. In addition to new arrivals, U.S. births to immigrant parents will be important to future growth in the country’s population. In 2018, the percentage of women giving birth in the past year was higher among immigrants (7.5%) than among the U.S. born (5.7%). While U.S.-born women gave birth to more than 3 million children that year, immigrant women gave birth to about 760,000.

How many immigrants have come to the U.S. as refugees?

Since the creation of the federal Refugee Resettlement Program in 1980, about 3 million refugees have been resettled in the U.S. – more than any other country.

In fiscal 2019, a total of 30,000 refugees were resettled in the U.S. The largest origin group of refugees was the Democratic Republic of the Congo, followed by Burma (Myanmar), Ukraine, Eritrea and Afghanistan. Among all refugees admitted in fiscal year 2019, 4,900 are Muslims (16%) and 23,800 are Christians (79%). Texas, Washington, New York and California resettled more than a quarter of all refugees admitted in fiscal 2018.

Where do most U.S. immigrants live?

Nearly half (45%) of the nation’s immigrants live in just three states: California (24%), Texas (11%) and Florida (10%). California had the largest immigrant population of any state in 2018, at 10.6 million. Texas, Florida and New York had more than 4 million immigrants each.

In terms of regions, about two-thirds of immigrants lived in the West (34%) and South (34%). Roughly one-fifth lived in the Northeast (21%) and 11% were in the Midwest.

In 2018, most immigrants lived in just 20 major metropolitan areas, with the largest populations in the New York, Los Angeles and Miami metro areas. These top 20 metro areas were home to 28.7 million immigrants, or 64% of the nation’s total foreign-born population. Most of the nation’s unauthorized immigrant population lived in these top metro areas as well.

How do immigrants compare with the U.S. population overall in education?

Immigrants in the U.S. as a whole have lower levels of education than the U.S.-born population. In 2018, immigrants were over three times as likely as the U.S. born to have not completed high school (27% vs. 8%). However, immigrants were just as likely as the U.S. born to have a bachelor’s degree or more (32% and 33%, respectively).

Educational attainment varies among the nation’s immigrant groups, particularly across immigrants from different regions of the world. Immigrants from Mexico and Central America are less likely to be high school graduates than the U.S. born (54% and 47%, respectively, do not have a high school diploma, vs. 8% of U.S. born). On the other hand, immigrants from every region except Mexico, the Caribbean and Central America were as likely as or more likely than U.S.-born residents to have a bachelor’s or advanced degree.

Among all immigrants, those from South Asia (71%) were the most likely to have a bachelor’s degree or more. Immigrants from Mexico (7%) and Central America (11%) were the least likely to have a bachelor’s or higher.

How many immigrants are working in the U.S.?

In 2017, about 29 million immigrants were working or looking for work in the U.S., making up some 17% of the total civilian labor force. Lawful immigrants made up the majority of the immigrant workforce, at 21.2 million. An additional 7.6 million immigrant workers are unauthorized immigrants, less than the total of the previous year and notably less than in 2007, when they were 8.2 million. They alone account for 4.6% of the civilian labor force, a dip from their peak of 5.4% in 2007. During the same period, the overall U.S. workforce grew, as did the number of U.S.-born workers and lawful immigrant workers.

Immigrants are projected to drive future growth in the U.S. working-age population through at least 2035. As the Baby Boom generation heads into retirement, immigrants and their children are expected to offset a decline in the working-age population by adding about 18 million people of working age between 2015 and 2035.

How well do immigrants speak English?

Among immigrants ages 5 and older in 2018, half (53%) are proficient English speakers – either speaking English very well (37%) or only speaking English at home (17%).

Immigrants from Mexico have the lowest rates of English proficiency (34%), followed by those from Central America (35%), East and Southeast Asia (50%) and South America (56%). Immigrants from Canada (96%), Oceania (82%), Europe (75%) and sub-Saharan Africa (74%) have the highest rates of English proficiency.  

The longer immigrants have lived in the U.S., the greater the likelihood they are English proficient. Some 47% of immigrants living in the U.S. five years or less are proficient. By contrast, more than half (57%) of immigrants who have lived in the U.S. for 20 years or more are proficient English speakers.

Among immigrants ages 5 and older, Spanish is the most commonly spoken language. Some 42% of immigrants in the U.S. speak Spanish at home. The top five languages spoken at home among immigrants outside of Spanish are English only (17%), followed by Chinese (6%), Hindi (5%), Filipino/Tagalog (4%) and French (3%).

How many immigrants have been deported recently?

Around 337,000 immigrants were deported from the U.S. in fiscal 2018, up since 2017. Overall, the Obama administration deported about 3 million immigrants between 2009 and 2016, a significantly higher number than the 2 million immigrants deported by the Bush administration between 2001 and 2008. In 2017, the Trump administration deported 295,000 immigrants, the lowest total since 2006.

Immigrants convicted of a crime made up the less than half of deportations in 2018, the most recent year for which statistics by criminal status are available. Of the 337,000 immigrants deported in 2018, some 44% had criminal convictions and 56% were not convicted of a crime. From 2001 to 2018, a majority (60%) of immigrants deported have not been convicted of a crime.

How many immigrant apprehensions take place at the U.S.-Mexico border?

The number of apprehensions at the U.S.-Mexico border has doubled from fiscal 2018 to fiscal 2019, from 396,579 in fiscal 2018 to 851,508 in fiscal 2019. Today, there are more apprehensions of non-Mexicans than Mexicans at the border. In fiscal 2019, apprehensions of Central Americans at the border exceeded those of Mexicans for the fourth consecutive year. The first time Mexicans did not make up the bulk of Border Patrol apprehensions was in 2014.

How do Americans view immigrants and immigration?

While immigration has been at the forefront of a national political debate, the U.S. public holds a range of views about immigrants living in the country. Overall, a majority of Americans have positive views about immigrants. About two-thirds of  Americans (66%) say immigrants strengthen the country “because of their hard work and talents,” while about a quarter (24%) say immigrants burden the country by taking jobs, housing and health care.

Yet these views vary starkly by political affiliation. Among Democrats and Democratic-leaning independents, 88% think immigrants strengthen the country with their hard work and talents, and just 8% say they are a burden. Among Republicans and Republican-leaning independents, 41% say immigrants strengthen the country, while 44% say they burden it.

Americans were divided on future levels of immigration. A quarter said legal immigration to the U.S. should be decreased (24%), while one-third (38%) said immigration should be kept at its present level and almost another third (32%) said immigration should be increased.

Note: This is an update of a post originally published May 3, 2017, and written by Gustavo López, a former research analyst focusing on Hispanics, immigration and demographics; and Kristen Bialik, a former research assistant.

CORRECTION (Sept. 21, 2020): An update to the methodology used to tabulate figures in the chart “Among new immigrant arrivals, Asians outnumber Hispanics” has changed all figures from 2001 and 2012. This new methodology has also allowed the inclusion of the figure from 2000. Furthermore, the earlier version of the chart incorrectly showed the partial year shares of Hispanic and Asian recent arrivals in 2015; the corrected complete year shares are 31% and 36%, respectively.
