Immigration to the United States has been a major source of population growth and cultural change throughout much of its history. In absolute numbers, the United States has by far the highest number of immigrants in the world, with 50,661,149 people as of 2019. This represents 19.1% of the 244 million international migrants worldwide, and 14.4% of the United States' population. In 2018, there were almost 90 million immigrants and U.S.-born children of immigrants in the United States, accounting for 28% of the overall U.S. population.
The Emergency Quota Act, also known as the Emergency Immigration Act of 1921, the Immigration Restriction Act of 1921, the Per Centum Law, and the Johnson Quota Act, was formulated mainly in response to the large influx of Southern and Eastern Europeans and restricted their immigration to the United States. Although intended as temporary legislation, it "proved, in the long run, the most important turning-point in American immigration policy" because it added two new features to American immigration law: numerical limits on immigration and the use of a quota system for establishing those limits, which came to be known as the National Origins Formula.
The United States had an official estimated resident population of 334,914,895 on July 1, 2023, according to the U.S. Census Bureau. This figure includes the 50 states and the District of Columbia but excludes the population of five unincorporated U.S. territories as well as several minor island possessions. The United States is the third most populous country in the world, and the most populous in the Americas and the Western Hemisphere. The Census Bureau showed a population increase of 0.4% for the twelve-month period ending in July 2022, below the world average annual rate of 0.9%. The total fertility rate in the United States estimated for 2022 is 1.665 children per woman, which is below the replacement fertility rate of approximately 2.1.
The Immigration and Nationality Act of 1952, also known as the McCarran–Walter Act, codified under Title 8 of the United States Code, governs immigration to and citizenship in the United States. It came into effect on June 27, 1952. The legislation consolidated various immigration laws into a single text. Officially titled the Immigration and Nationality Act, it is often referred to as the 1952 law to distinguish it from the 1965 legislation. This law increased the quota for Europeans outside Northern and Western Europe, gave the Department of State authority to reject entries affecting native wages, eliminated 1880s bans on contract labor, set a minimum quota of one hundred visas per country, and promoted family reunification by exempting citizens' children and spouses from numerical caps.
Egyptian Americans are Americans of partial or full Egyptian ancestry. The 2016 US Census estimated the number of people with Egyptian ancestry at 256,000, most of whom are from Egypt's Christian Orthodox Coptic minority. Egyptian Americans may also include the Egyptian foreign-born population in the United States. The US Census Bureau estimated in 2016 that there were 181,677 foreign-born Egyptians in the United States. They represented around 0.4% of the total US foreign-born population as 42,194,354 first-generation immigrants in 2016. Egyptians are concentrated in New York City and Los Angeles. California has the largest Egyptian population by state.
Foreign-born people are those born outside of their country of residence. Foreign born are often non-citizens, but many are naturalized citizens of the country in which they live, and others are citizens by descent, typically through a parent.
The National Origins Formula is an umbrella term for a series of qualitative immigration quotas in America used from 1921 to 1965, which restricted immigration from the Eastern Hemisphere on the basis of national origin. These restrictions included legislation and federal acts. Since there is no one formula that can account for each law or restriction across the decades, as the scale, variables, and demographic characteristics change per law, the concept of National Origins Formula is best described as a collection of quantitative data considerations in immigration and migration laws in the United States.
Foreign nationals (aliens) can violate US immigration laws by entering the United States unlawfully or lawfully entering but then remaining after the expiration of their visas, parole, or temporary protected status. Illegal immigration has been a matter of intense debate in the United States since the 1980s.
Iraqi Americans are American citizens of Iraqi descent. As of 2015, the number of Iraqi Americans is around 145,279, according to the United States Census Bureau.
African immigration to the United States refers to immigrants to the United States who are or were nationals of modern African countries. The term African in the scope of this article refers to geographical or national origins rather than racial affiliation. From the Immigration and Nationality Act of 1965 to 2017, Sub-Saharan African-born population in the United States grew to 2.1 million people.
Caribbean Americans or West Indian Americans are Americans who trace their ancestry to the Caribbean. Caribbean Americans are a multi-ethnic and multi-racial group that trace their ancestry further in time mostly to Africa, as well as Asia, the Indigenous peoples of the Americas, and to Europe. As of 2016, about 13 million — about 4% of the total U.S. population — have Caribbean ancestry.
The history of immigration to the United States details the movement of people to the United States from the colonial era to the present day. Throughout U.S. history, the country experienced successive waves of immigration, particularly from Europe and later on from Asia and Latin America. Colonial-era immigrants often repaid the cost of transoceanic transportation by becoming indentured servants in which the new employer paid the ship's captain. In the late 19th century, immigration from China and Japan was restricted. In the 1920s, restrictive immigration quotas were imposed but political refugees had special status. Numerical restrictions ended in 1965. In recent years, the largest numbers of immigrants to the United States have come from Asia and Central America.
South African Americans are Americans who have full or partial ancestry from South Africa. As of 2021, there were approximately 123,461 people born in South Africa who were living in the United States.
Citizenship of the United States is a legal status that entails Americans with specific rights, duties, protections, and benefits in the United States. It serves as a foundation of fundamental rights derived from and protected by the Constitution and laws of the United States, such as freedom of expression, due process, the rights to vote, live and work in the United States, and to receive federal assistance.
Kazakh Americans are Americans of full or partial Kazakh ancestry. Although in the 1960s the population of Kazakh origin in United States was estimated in 3,000 people, the Census 2000 puts the population size in less of 300 people. According to the American Community Survey in 2010-2012 there were more than 23,000 people born in Kazakhstan, but not all of them are of Kazakh ethnicity.
There have been a variety of ethnic groups in Baltimore, Maryland and its surrounding area for 12,000 years. Prior to European colonization, various Native American nations have lived in the Baltimore area for nearly 3 millennia, with the earliest known Native inhabitants dating to the 10th millennium BCE. Following Baltimore's foundation as a subdivision of the Province of Maryland by British colonial authorities in 1661, the city became home to numerous European settlers and immigrants and their African slaves. Since the first English settlers arrived, substantial immigration from all over Europe, the presence of a deeply rooted community of free black people that was the largest in the pre-Civil War United States, out-migration of African-Americans from the Deep South, out-migration of White Southerners from Appalachia, out-migration of Native Americans from the Southeast such as the Lumbee and the Cherokee, and new waves of more recent immigrants from Latin America, the Caribbean, Asia and Africa have added layers of complexity to the workforce and culture of Baltimore, as well as the religious and ethnic fabric of the city. Baltimore's culture has been described as "the blending of Southern culture and [African-American] migration, Northern industry, and the influx of European immigrants—first mixing at the port and its neighborhoods...Baltimore’s character, it’s uniqueness, the dialect, all of it, is a kind of amalgamation of these very different things coming together—with a little Appalachia thrown in...It’s all threaded through these neighborhoods", according to the American studies academic Mary Rizzo.
Chinese languages, mostly Cantonese, are collectively the third most-spoken language in the United States, and are mostly spoken within Chinese-American populations and by immigrants or the descendants of immigrants, especially in California and New York. Around 2004, over 2 million Americans spoke varieties of Chinese, with Mandarin becoming increasingly common due to immigration from mainland China and to some extent Taiwan. Within this category, approximately one third of respondents described themselves as speaking Cantonese or Mandarin specifically, with the other two thirds answering "Chinese", despite the lack of mutual intelligibility between different varieties of Chinese. This phenomenon makes it more difficult to readily identify the relative prevalence of any single Chinese language in the United States.
Fijian Americans refers to Americans citizens who are native to or descendants of people from the Fiji Islands. Most of Fijian Americans are of ethnic iTaukei or Indian descent. Fijian Americans are considered Pacific Islanders in the United States Census. There are 32,304 Fijian Americans living in the U.S. as of 2010, with 75% of them living in the state of California alone, especially in Sacramento County. The American Community Survey 2015-2019 counted a Fijian immigrant population of 47,000.
