In 2022, an estimated 10.99 million unauthorized immigrants were living in the United States. This is an increase from about 3.5 million unauthorized immigrants who lived in the United States in 1990.

The estimated population of unauthorized immigrants in the U.S. stands at around 11 million people. Although the number has stabilized, the United States has seen a spike in migrant encounters in the last few years, with over two million cases registered by the U.S. Border Patrol in 2023. This is a slight decrease from the previous year, when there were over 2.2 million cases registered. Due to its proximity and shared border, Mexico remains the leading country of origin for most undocumented immigrants in the U.S., with California and Texas being home to the majority.

Immigration and political division

Despite the majority of the population having immigrant roots, the topic of immigration in the U.S. remains one of the country’s longest-standing political debates. Support among Republicans for restrictive immigration has grown alongside Democratic support for open immigration. This growing divide has deepened the polarization between the two major political parties, stifling constructive dialogue and impeding meaningful reform efforts and as a result, has led to dissatisfaction from all sides. In addition to general immigration policy, feelings toward illegal immigration in the U.S. also vary widely. For some, it's seen as a significant threat to national security, cultural identity, and economic stability. This perspective often aligns with support for stringent measures like Trump's proposed border wall and increased enforcement efforts. On the other hand, there are those who are more sympathetic toward undocumented immigrants, as demonstrated by support for the Deferred Action for Childhood Arrivals (DACA) program.

In January 2022, it was estimated that about 1.85 million male illegal immigrants living in the United States were aged between 35 and 44 years old. In that same year, it was estimated that 1.52 million female illegal immigrants living in the U.S. were between 35 and 44 years old.

The statistic shows the number of illegal immigrants living in the U.S. from 2000 to 2012, as estimated by the Department of Homeland Security. As of 2012, about 11.4 million illegal immigrants were living in the United States.

In 2022, about 2.58 million illegal aliens were apprehended in the United States. This was a significant increase from the previous year, when there were around 1.87 million illegal aliens apprehended nationwide. Apprehensions refer to Border Patrol apprehensions and ICE administrative arrests.

In the fiscal year of 2020, the United States Border Patrol apprehended 400,651 people trying to cross the Southwest border. This was a significant decrease from the previous year, when there were 851,508 apprehensions by Border Patrol at the Southwest border. This decrease is likely due to the impact of the coronavirus (COVID-19) pandemic.

In 2019, California had the highest population of unauthorized immigrants, at around 2.74 million. The overall figure for the United States was estimated to be around 11.05 million unauthorized immigrants.

This statistic shows the estimated number of illegal immigrants in the United States labor force from 2000 to 2014. In 2014, an estimated 8 million illegal immigrants participated in the U.S. labor force.

Between 1820 and 1957, more than six million people emigrated from Germany to the United States. The period with the highest levels of migration came during the 1850s and the 1880s, and over 250 thousand documented migrants came to the US from Germany in 1882 alone. The reasons for these mass migrations were not linked to individual events, but were because of the improved access to trans-Atlantic travel, poor economic opportunities at home (particularly for farmers, who struggled with the rapid industrialization of Germany), and to escape religious persecution in Europe. The periods with the lowest levels of migration from Germany were between 1915 and 1945, and were likely caused by the First and Second World Wars, and also the Great Depression.

In 2024, the net migration rate in France reached 152,000. In recent years Europe and France have seen more people arrive than depart. The net migration rate is the difference between the number of immigrants (people coming into an area) and the number of emigrants (people leaving an area) throughout the year. France's highest net migration rate was reached in 2018 when it amounted to 201,000. Armed conflicts and economic migration are some of the reasons for immigration in Europe. The refugee crisis Studies have shown that there were 331,000 immigrant arrivals in France in 2022, which has risen since 2014. The migrant crisis, which began in 2015 in Europe, had an impact on the migration entry flows not only in France but in all European countries. The number of illegal border crossings to the EU over the Eastern Mediterranean route reached a record number of 885,386 crossings in 2015. Immigration in France Since the middle of the 19th century, France has attracted immigrants, first from European countries (like Poland, Spain, and Italy), and then from the former French colonies. In 2023, there were approximately 8.9 million people foreign-born in France. Most of them were living in the Ile-de-France region, which contains Paris, and in Provence-Alpes-Côte d’Azur in the Southeastern part of the country. In 2022, the majority of immigrants arriving in France were from Africa and Europe.

This statistic shows the number of unauthorized Indian immigrants in the United States from 1990 to 2014. As of 2014, around 500,000 unauthorized immigrants in the United States were from India.

In 2023, around 1.93 million people immigrated to Germany. Numbers fluctuated during the time period covered in the graph at hand, peaking in 2015 during the high point of Europe’s refugee crisis. Significantly lower figures in 2020 may be attributed to the first year of the coronavirus (COVID-19) pandemic, and subsequent restrictions implemented by the German government on entering the country, in order to control the spread of the disease. Immigration to Germany “Immigrant” is a term used from the point of view of the receiving country, or the country being migrated to by a person. While reasons for and circumstances leading to an immigrant entering a foreign country may vary, they often include love, include seeking residence, employment, family reunions, or applying for asylum. Various countries are represented among foreigners living in Germany, though currently the leading three by numbers are Turkey, Ukraine, and Syria. Around 5.2 million immigrants living in Germany do not need a residence permit due to having EU citizenship, and therefore being allowed freedom of movement based on EU law. Another 2.64 million immigrants were granted an unlimited permit to stay in Germany. The near future Germany remains a popular choice for immigrants, even in currently challenging economic and political times. Welfare benefits, healthcare, and various support initiatives for those moving to or arriving in the country are on the list of selling points, though in practice, difficulties may be encountered depending on individual situations and laws in different German federal states. While the unemployment rate among foreigners living in Germany had gone up in 2020, it dropped again in the following years, but increased once more in 2023 and 2024 to over 16 percent. The country is Europe’s largest economy, housing many global players in various industries, which continues to attract jobseekers, despite these very industries facing struggles of their own brought on both by the ongoing coronavirus pandemic and geopolitical events in Europe.

Significantly more men were apprehended by the United States Border Patrol than women in the the fiscal year of 2020. Nationwide, 329,347 men were apprehended by Border Patrol in that year, compared to 75,678 women who were apprehended.

In the nineteenth and twentieth centuries, the majority of documented migration to the United States of American came from European countries. Between 1820 and 1957, of the approximate 41 million migrants to the US, over 34 million of these came from Europe. The most commonly documented countries of origin during this time were Germany (6.6 million), Italy (4.9 million), Ireland (4.6 million), Great Britain (4.5 million), and Russia (3.4 million). The first wave of mass migration came in the 1850s, as the Great famine crippled Ireland's population, and many in rural areas of mainland Europe struggled to adapt to industrialization, and economic opportunities attracted many in the 1870s, following the American Civil War. The 1880s saw another wave, as steam powered ships and lower fares made trans-Atlantic journeys much more affordable. The first wave of mass migration from Eastern and Southern Europe also arrived at this time, as industrialization and agricultural advancements led to high unemployment in these regions.

The majority of migrants to the United States settled in major urban centers, which allowed the expansion of industry, leading to the United States' emergence as one of the leading global economies at the turn of the twentieth century. The largest wave of migration to the United states during this period came in the first fifteen years of the 1900s. The influx of migrants from Northern and Western Europe had now been replaced by an influx from Eastern and Southern Europe (although migration from the British Isles was still quite high during this time). European migration fell to it's lowest levels in eighty years during the First World War, before fluctuating again in the interwar period, due to the Great Depression. As the twentieth century progressed, the continent with the highest levels of migration to the US gradually changed from Europe to Latin America, as economic opportunities in Western Europe improved, and the US' relationship with the Soviet Union and other Eastern, communist states became complicated.

The largest number of immigrants in Germany were from Ukraine, as of 2023. The top three origin countries were rounded up by Romania and Turkey. Immigrants are defined as having left a country, which may be their home country, to permanently reside in another. Upon arriving, immigrants do not hold the citizenship of the country they move to. Immigration in the EU All three aforementioned countries are members of the European Union, which means their citizens have freedom of movement between EU member states. In practice, this means that citizens of any EU member country may relocate between them to live and work there. Unrestricted by visas or residence permits, the search for university courses, jobs, retirement options, and places to live seems to be defined by an enormous amount of choice. However, even in this freedom of movement scheme, immigration may be hampered by bureaucratic hurdles or financial challenges. Prosperity with a question mark While Germany continues to be an attractive destination for foreigners both in and outside the European Union, as well as asylum applicants, it remains to be seen how current events might influence these patterns, whether the number of immigrants arriving from certain countries will shift. Europe’s largest economy is suffering. Climbing inflation levels in the last few months, as well as remaining difficulties from the ongoing coronavirus (COVID-19) pandemic are affecting global economic development. Ultimately, future immigrants may face the fact of moving from one struggling economy to another.

For the year ending June 2024, approximately 1.2 million people migrated to the United Kingdom, while 479,000 people migrated from the UK, resulting in a net migration figure of 728,000. There have consistently been more people migrating to the United Kingdom than leaving it since 1993 when the net migration figure was negative 1,000. Although migration from the European Union has declined since the Brexit vote of 2016, migration from non-EU countries accelerated rapidly from 2021 onwards. In the year to June 2023, 968,000 people from non-EU countries migrated to the UK, compared with 129,000 from EU member states. Immigration and the next UK election Throughout 2023, immigration, along with the economy and healthcare, was consistently seen by UK voters as one of the top issues facing the country. Despite a pledge to deter irregular migration via small boats, and controversial plans to send asylum applicants to Rwanda while their claims are being processed, the current government is losing the trust of the public on this issue. As of February 2024, 20 percent of Britons thought the Labour Party would be the best party to handle immigration, compared with 16 percent who thought the Conservatives would handle it better. With the next UK election expected at some point in 2024, the Conservatives are battling to improve their public image on this and many other issues. Historical context of migration The first humans who arrived in the British Isles, were followed by acts of conquest and settlement from Romans, Anglo-Saxons, Danes, and Normans. In the early modern period, there were also significant waves of migration from people fleeing religious or political persecution, such as the French Huguenots. More recently, large numbers of people also left Britain. Between 1820 and 1957, for example, around 4.5 million people migrated from Britain to America. After World War Two, immigration from Britain's colonies and former colonies was encouraged to meet labor demands. A key group that migrated from the Caribbean between the late 1940s and early 1970s became known as the Windrush generation, named after one of the ships that brought the arrivals to Britain.

In July 2024, the United States accepted 34 refugees from Ukraine. In fiscal year 2022 - which ended September 30, 2022 - the U.S. accepted a total of 1,610 Ukrainian refugees. The most Ukrainian refugees arrived in February 2022, the same month that Ukraine was invaded by Russia.In April 2022, the United States committed itself to welcoming 100,000 Ukrainian citizens and others fleeing Russian aggression in the region, but has so far only accepted 2,402 since the Russian invasion in February last year.

In the twelve months to June 2024, approximately 1.2 million people migrated to the United Kingdom, while 479,000 emigrated away from the country, resulting in a net migration figure of 728,000.

Historical migration from Africa to the United States is a delicate and complex issue. Although African-Americans make up more than one eighth of the current US population, the majority of their ancestors would most likely trace back to chattel slavery, which was prevalent throughout the Americas from the sixteenth to the nineteenth century. Although the slave trade was abolished in the US in 1808, illegal smuggling continued for years after (particularly from the Caribbean, as it was not abolished throughout the British Empire until 1833), and the practice of slavery continued until 1865. Another noteworthy point to remember is that the term "African-American" is generally applied to those with Sub-Saharan roots, and not to those from the predominantly Arabic, North Africa.

The data shown here applies only to free, documented migrants from the continent of Africa to the United States, between 1820 and 1957. In the nineteenth century, migration from Africa to the US was very low, and it was rare that more than one hundred migrants arrived in the US in any given year. Migration did increase in the first half of the twentieth century, however it was still the lowest out of all continents, including Oceania, which had a much lower overall population than Africa.

Between 1980 and 2024, the net migration rate of Mexico reached its highest value in 2009, with a rate of -0,28. In 2024, the migration rate was -0.8.
