Between 1820 and 1957, over 4.5 million people emigrated from Great Britain to the United States. The period with the highest levels of migration came during the 1860s, 70s and 80s, with almost 110 thousand people migrating in 1888 alone. The period with the lowest levels of migration came in the 1930s and early 40s, as the Great Depression caused an economic crisis across the globe, hitting the US and Great Britain particularly hard. Economic recovery in the late 1930s caused the migration rate to increase again, before the Second World War brought the numbers back down in the first half of the 1940s.

Over 13 million people legally migrated from Northern and Western Europe to the United States between 1820 and 19257. The majority of these migrants came from the British Isles, with over 4.6 million migrants coming from the island of Ireland, and over 4.5 million from Great Britain. After this there were just under 2.5 million immigrants from Scandinavia, and almost 1.5 million from the rest of Northwest Europe. The period with the highest levels of migration from Northwest Europe to the US was in the 1880s, as the Long Depression, increased industrialization and harsh winters continued to weaken Europe's agricultural sector, prompting many (mostly young men and their families) to migrate to the US in search of economic opportunities there. The period around 1850 also saw increased migration from Northwest Europe to the US, however the majority of this was due to the Great Famine in Ireland, which caused the death of over one million people due to starvation or famine-related illnesses, while another one million people migrated abroad to escape the hardships brought by the famine. The early 1930s saw the period with the lowest levels of emigration from Europe to the US, as the Great Depression made it difficult and impractical to migrate to the United States.

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.

In the year to June 2025, approximately 898,000 people migrated to the United Kingdom, while 693,000 people migrated from the country, resulting in a net migration figure of 204,000. There have consistently been more people migrating to the United Kingdom than leaving it since 1993 when approximately 1,000 more people left the country than arrived. 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 2024 election Since late 2022, immigration, along with the economy and healthcare, has consistently been 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, Rishi Sunak's Conservative government lost the trust of the public on this issue. On the eve of the last election, 20 percent of Britons thought the Labour Party would be the best party to handle immigration, compared with 13 percent who thought the Conservatives would handle it better. Sunak and the Conservatives went on to lose this election, suffering their worst defeat in modern elections. 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 labour 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.

Policy might partly shape the English-language acquisition of Hispanics migrating to the U.S. mainland, particularly policies related to limited-English-language disability benefits and immigration reform. Using data from the American Community Survey, we find that island-born Puerto Ricans on the U.S. mainland, as U.S. citizens, may have lower incentives to learn English than Hispanic immigrants because of their higher participation in LEP disability programs. However, among Mexican immigrants, recent immigration reform aimed at interior enforcement might have increased incentives for Mexican immigrants to learn English to reduce their probability of detection, if speaking English proxies for undocumented status.

Between 1500 and 1820, an estimated 2.58 million Europeans migrated to the Americas, namely from the British Isles, Portugal, Spain, France and Germany. Until the mid-1600s, the majority of European migrants were from the Iberian Peninsula, as Portugal and Spain had a 150 year head start over other European powers when building their overseas empires. However, by the end of the century, more settlers from the British Isles had emigrated to the New World than from Spain or Portugal; the majority of which migrated to British colonies in the Caribbean as indentured servants or prisoners. The 18th century also saw migrants from other European nations begin to migrate en masse, particularly those from France and the German states, although migration from the British Isles and Portugal remained at the highest levels.

In comparison to the almost 2.6 million Europeans migrants, it is estimated that over 8.6 million Africans were forced across the Atlantic during this time period, as part of the transatlantic slave trade. The first half of the 19th century saw the demise of the transatlantic slave trade, which was followed by an influx of white migration to the Americas from across Europe; this contributed heavily to reversing demographic trends and making those with African ancestry an ethnic minority in most American countries today.

While the European colonization and settlement of other world regions largely began in the 16th and 17th centuries, it was not until the 19th century when the largest waves of migration began to take place. In early years, migration rates were comparatively low; in all of the Americas, the slave population actually outnumbered that of Europeans for most of the given period. Then, with the development of steam ships, intercontinental travel became more affordable and accessible to the masses, and voluntary migration from Europe rose significantly. Additionally, larger numbers of Asian migrants, especially from India and China, migrated to Australia, the Caribbean, and U.S. from the mid-1800s; although the U.S. and Australia both introduced policies that limited or prevented Asian immigration throughout most of the early 1900s. International migration between 1913 and 1950 was also comparatively low due to the tumultuous nature of the period, which involved both World Wars and the Great Depression.

The literature in political science considers (sometimes inaccurate) perceptions of immigrants as a factor in anti-immigration attitudes among natives, but much less is known about perceptions regarding immigrants from specific regions. In this paper, I explore Americans’ perceptions about immigrants from Africa, Asia, Europe, Latin America, and the Middle East. To measure these perceptions, I apply a conjoint experiment with a multinomial outcome, in which respondents are asked to categorize hypothetical immigrants as coming from one of the five regions. Results from a nationally diverse sample demonstrate that immigrants from all regions other than Europe are associated with speaking poor English. Immigrants from Latin America are also associated with welfare dependency and rule-breaking behavior, while the opposite is true for immigrants from Asia. These negative perceptions may at least partly explain opposition to non-European, and specifically Latin American, immigration in the United States.

Are the English proficiency and social outcomes of US immigrants the result of their cultural preferences or of more fundamental constraints? Using 2000 census microdata, we relate the English proficiency, marriage, fertility, and residential location variables of immigrants to their age at the time of arrival in the United States, and, in particular, whether that age fell within the "critical period" of language acquisition. We interpret the differences between younger and older arrivers as effects of English language skills and construct an instrumental variable for English language skills. Two-stage-least-squares estimates suggest English proficiency increases the likelihood of divorce and intermarriage. It decreases fertility and, for some, ethnic enclave residence.

Abstract

This dataset, a product of the Trade Team - Development Research Group, is part of a larger effort in the group to measure the extent of the brain drain as part of the International Migration and Development Program. It measures international skilled migration for the years 1975-2000.

The methodology is explained in: "Tendance de long terme des migrations internationals. Analyse à partir des 6 principaux pays recerveurs", Cécily Defoort.

This data set uses the same methodology as used in the Docquier-Marfouk data set on international migration by educational attainment. The authors use data from 6 key receiving countries in the OECD: Australia, Canada, France, Germany, the UK and the US.

It is estimated that the data represent approximately 77 percent of the world’s migrant population.

Bilateral brain drain rates are estimated based observations for every five years, during the period 1975-2000.

This graph shows the distribution of nationalities among documented immigrants who arrived in the United States between 1820 and 1870. As we can see, over seven million people arrived in the US in this 50 year period, with the majority coming from Ireland, Germany and Britain. The largest groups, by far, were Irish and German, who together made up roughly two thirds of all immigrants to the US during this time. The reasons for this were because of the Irish Potato famine from 1845 to 1849, which resulted in the death or emigration of twenty to twenty five percent of the total Irish population, and a number of internal factors in Germany such as economic migration for farmers affected by industrialization, political/religious asylum, and in order to avoid conscription. One noteworthy exclusion from the information is of those transported to US as slaves, whose information was not recorded in this statistic (although the slave trade was abolished in 1808, the practice continued in the decades that followed).

Amid debates on whether and how to admit immigrants to the United States, policies designed to support immigrants after they arrive receive little attention. We estimate the effects of English language training for adult immigrants on participants’ civic and economic outcomes using randomized enrollment lotteries from a public adult ESOL program in Massachusetts. Participation doubles voter participation and increases annual earnings by $2,400 (56%). Increased tax revenue from earnings gains cover program costs over time, generating a 6% return for taxpayers. Ours is the first randomized evaluation of adult English language training as a standalone intervention in the United States.

In 2024, approximately 517,000 people emigrated from the United Kingdom, 77,000 of which were British citizens, 218,000 were EU citizens, and a further 222,000 were non-EU citizens.
