The National Origins Formula is an umbrella term for a series of quantitative 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.

71-440: Temporary measures establishing quota limits per country based on the makeup of the foreign-born population residing in the U.S. were introduced in 1921 ( Emergency Quota Act ) and 1924 ( Immigration Act of 1924 ); these were replaced by a permanent quota system based on each nationality's share of the total U.S. population as of 1920 , which took effect on July 1, 1929 and governed American immigration law until December 1, 1965 (when

142-640: A presidential memorandum ordering the exclusion of illegal immigrants from the numbers in the 2020 census that are used to apportion seats in the House of Representatives. The COVID-19 pandemic made the collection of the census results difficult, and the department had extended the deadline to complete collection to October 31 instead of July 31, 2020. On August 3, the department announced its Replan Schedule that would end collection early on September 30, aware this would leave them with incomplete data that they would have to estimate total numbers to complete. This move

213-716: A census was taken in Virginia , and people were counted in almost all of the British colonies that became the United States . Between 1781 and 1786, the first "actual enumeration" was conducted separately in each state and compiled by John Kean for consideration at the Constitutional Convention in 1787. Throughout the years, the country's needs and interests became more complicated. This meant that statistics were needed to help people understand what

284-451: A coherent snapshot and avoid double counting. The actual census-taking begins before this date and extends for months thereafter. In 2020, the earliest responses were collected starting January 21 in remote parts of Alaska, and March 12 for most Americans. In addition to its primary purpose of reapportioning the House of Representatives, census data are used for a wide variety of applications, including: The census has historically and up to

355-804: A number of controversies and legal challenges under the Trump administration due to President Donald Trump 's policies on illegal immigration, particularly those undocumented in the country. Prior to the publication of the census, the Commerce Department stated its intention to add a question asking responders about their immigration status, which many states and activists stated would cause illegal immigrants to not respond out of fear of prosecution and lead to undercounting, affecting state representation and federal funding. The Supreme Court case Department of Commerce v. New York , decided in June 2019, found

426-555: A population.) The national origins formula prescribed by the Immigration Act of 1924 , effective 1929, capped total annual quota immigration from outside the Western Hemisphere at 150,000. The quota for each country was to be computed as a fraction of 150,000 in a ratio proportional to the number of U.S. inhabitants of each national origin as a share of total inhabitants in 1920, with a minimum quota of 100. Due to

Appointed U.S. Marshals of each judicial district hired assistant marshals to conduct the actual enumeration. The census enumerators were typically from the village or neighborhood and often knew the residents. Before enabling self-identification on

568-821: A system with one quota for the Western Hemisphere, and one for the Eastern Hemisphere. It marked a significant change in American immigration policy. Emergency Quota Act 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 (ch. 8, 42  Stat.   5 of May 19, 1921),

639-399: A total of 3,172,444 European Americans ; their 40,324,400 colonial stock descendants in 1920 were allocated into national origin blocs proportional to the ratio of nationalities that had existed in the 1790 population, adjusted to account for natural growth as of 1920. The national origins of the colonial stock had to be estimated by careful analysis of the limited information recorded in

710-485: A total pool of 150,000 annual quota immigrants. This formula was used until the Immigration and Nationality Act of 1952 adopted a simplified formula limiting each country to a quota of one-sixth of one percent of that nationality's 1920 population count, with a minimum quota of 100. The formula required classification of the national origins by birth or ancestry of all white Americans , except those having origins in

The first census after the American Revolution was taken in 1790 under Secretary of State Thomas Jefferson . There have been 23 federal censuses since that time. The census includes territories of the United States . The United States Census Bureau is responsible for conducting

852-790: Is controversial; up to one-third of all U.S. residents do not respond to repeated reminders. In recent censuses, the nonresponse rate has been less than 1% (it was about 0.4% in 2010), but during the 2020 census, as of September 11, many experts believed the nonresponse rate could reach double digits. By October 19, 2020, all states had topped a 99% response rate, with all but one state having a nonresponse rate below 0.1%. The Census Bureau estimates that in 1970 over six percent of African Americans went uncounted, whereas only around two percent of European Americans went uncounted. Democrats often argue that modern sampling techniques should be used so that more accurate and complete data can be inferred. Republicans often argue against such sampling techniques, stating

923-535: Is mandated by Article I , Section 2 of the United States Constitution , which states: " Representatives and direct Taxes shall be apportioned among the several States... according to their respective Numbers... . The actual Enumeration shall be made within three years after the first meeting of the Congress of the United States , and within every subsequent Term of ten Years". Section 2 of

994-980: Is part of the United States Department of Commerce . Title 13 of the United States Code governs how the census is conducted and how its data are handled. Information is confidential as per 13 U.S.C.   § 9 . The census law, coupled with the Sentencing Reform Act of 1984 ( Title 18 of the United States Code , Sections 3551, 3559, and 3571), provides for penalties of up to $ 5,000 for not responding or for willfully providing false answers to any question. Decennial U.S. census figures are based on actual counts of persons dwelling in U.S. residential structures. They include citizens, non-citizen legal residents, non-citizen long-term visitors and undocumented immigrants. The Census Bureau bases its decision about whom to count on

1065-480: Is that it was chosen in 1952 as slightly higher than the average female life expectancy, 71.6. Another explanation (which disputes the life expectancy number) is that this number is a holdover from 1942, when a disagreement between the Census Bureau and the National Archives was resolved with 1870 as the boundary between confidential and public records. The individual census data most recently released to

1136-551: Is the number of inhabitants of any given national origin and q is the quota, hence to convert n into q required multiplication of n by ⁠ 150,000 / 89,506,558 ⁠ = 0.001675854857 . For example, the number of U.S. inhabitants in 1920 who were derived from the United Kingdom was fixed at 39,216,333 so the formula f = ⁠ 39,216,333 / 89,506,558 ⁠ = ⁠ q / 150,000 ⁠ . The formula could thus be solved for q as: Or

1207-632: The Fourteenth Amendment amended Article I, Section 2 to include that the "respective Numbers" of the "several States" will be determined by "counting the whole number of persons in each State, excluding Indians not taxed." The United States Census Bureau (officially the Bureau of the Census, as defined in Title 13 U.S.C. § 11) is responsible for the United States census. The Bureau of the Census

1278-592: The Immigration and Nationality Act of 1952 , effective 1953, was simplified to multiply n by ⁠ 1 / 6 ⁠ of 1% (equivalent to decimal 0.00166666666̅) to arrive at roughly equivalent (but slightly reduced) quotas by a much streamlined process e.g. Under the Immigration and Nationality Act of 1965 , quotas were temporarily retained, but all unused quota spots each year were pooled and made available to other countries effective December 1, 1965. The National Origins Formula fully ended on July 1, 1968, replaced by simple broad numerical limitations of 120,000 from

1349-419: The Immigration and Nationality Act of 1965 abolished it). The National Origins Formula aimed to preserve the existing ethnic proportions of the population as calculated according to data from the 1920 Census of Population. The 1921 Emergency Quota Act restricted immigration to 3% of foreign-born persons of each nationality that resided in the United States in 1910. The Immigration Act of 1924 , also called

1420-484: The Immigration and Nationality Act of 1965 . Non-citizens of the U.S. who are citizens or nationals of 40 countries are currently exempted from a visa requirement under the Visa Waiver Program . Immigration inspectors differently handle visa packets depending on whether they are non-immigrant (visitor) or immigrant (permanent admission). Under the original, unmodified law, non-immigrant visas were kept at

1491-735: The National Origins Formula . The Emergency Quota Act restricted the number of immigrants admitted from any country annually to 3% of the number of residents from that country living in the United States as of the 1910 Census . That meant that people from Northern and Western Europe had a higher quota and were more likely to be admitted to the US than those from Eastern or Southern Europe or from non-European countries. However, professionals were to be admitted without regard to their country of origin. Also, no limits were set on immigration from Canada, Newfoundland , Cuba, Mexico, or

The easiest to classify were the two most recently-arrived generations of immigrants, accounting for 1/3 of the 1920 total: Calculation of the colonial stock proved challenging, and delayed formula implementation from 1927 to 1929. The 1790 Census recorded

President Harry Truman vetoed it because of its continued use of national quotas, but the Act was passed over his veto. The quotas were in addition to 600,000 refugees admitted from Europe after World War II. The National Origins Formula was abolished by the Immigration and Nationality Act of 1965 , which introduced

It is also distinct from local censuses conducted by some states or local jurisdictions . The U.S. census

1988-500: The Emergency Quota Act of 1921 to the final quota year of 1965. The 1922 and 1925 systems based on dated census records of the foreign-born population were intended as temporary measures, and were replaced by the 1924 Act's National Origins Formula based on the 1920 Census of the total U.S. population, effective July 1, 1929.

After June 30, 1927, total immigration from all countries will be limited to 150,000, with allocations by country based upon national origins of inhabitants according to the census of 1920. The quota system applied only to non-Asian immigrants. It aimed to reduce

2201-518: The U.S. Constitution requires an "actual enumeration" for apportionment of House seats, and that political appointees would be tempted to manipulate the sampling formulas. Groups like the Prison Policy Initiative assert that the census practice of counting prisoners as residents of prisons, not their pre-incarceration addresses, leads to misleading information about racial demographics and population numbers.

2272-528: The U.S. House of Representatives ". According to the Census Bureau, "Census Day" has been April 1 since 1930. Previously, from 1790 to 1820, the census counted the population as of the first Monday in August. It moved to June 1 in 1830, (June 2 in 1890), April 15 in 1910, and January 1 in 1920. Because people are born, die, and move during the year, the census counts people where they were or expect to be living on this specific reference date in an attempt to get

2343-500: The Union, as well as to other areas under U.S. sovereignty or jurisdiction. There were so many more inquiries of all kinds in the census of 1880 that almost a full decade was needed to publish all the results. In response to this, the census was mechanized in 1890, with tabulating machines made by Herman Hollerith . This reduced the processing time to two and a half years. For the first six censuses (1790–1840), enumerators recorded only

Since 2013, the Census Bureau began discussions on using technology to aid data collection starting with the 2020 census. In 2020, every household received an invitation to complete the census over the Internet, by phone or by paper questionnaire. For years between the decennial censuses,

2627-438: The censuses, the U.S. Census Bureau relied on local people to have some knowledge of residents. Racial classification was made by the census enumerator in these decades, rather than by the individual. The 1890 census was the first to be compiled using the new tabulating machines invented by Herman Hollerith . The net effect of the many changes from the 1880 census (the larger population, the number of data items to be collected,

The act did not apply to countries with bilateral agreements with the US or to Asian countries listed in the Immigration Act of 1917 , known as the Asiatic Barred Zone Act. The Immigration Act of 1924 reduced the quota to 2% of countries' representation in the 1890 census , when a fairly small percentage of the population

Replies are obtained from individuals and establishments only to enable the compilation of such general statistics. The confidentiality of these replies is very important. By law, no one—neither the census takers nor any other Census Bureau employee—is permitted to reveal identifiable information about any person, household, or business. By law ( Pub.

The numbers do not purport to represent 'pure' discrete individuals of monoethnic backgrounds. Rather

3053-511: The figures reflect how the population would have naturally grown if each succeeding generation from the 1790 colonial stock had only mated endogamously among their own co-ethnics in the subsequent 130 years, estimating the diffusion of 'blood' among white Americans as a collective whole. In reality, exogamy was common with many white Americans being of mixed European ancestries (measuring 'blood' in modern parlance akin to DNA test results measuring an individual's ancestral makeup, applied to

3124-481: The final quota year of 1965. The 1922 and 1925 systems based on dated census records of the foreign-born population were intended as temporary measures; the full National Origins Formula based on the 1920 Census of the U.S. population took effect on July 1, 1929. The Immigration and Nationality Act of 1952 retained but relaxed the National Origins Formula. It modified the ratios to be based on

In 1924, the only Census Bureau estimate of colonial stock makeup had been published more than a decade prior in 1909 report A Century of Population Growth , which put the 1790 population at 82.1% English (incl. Welsh ), 7.0% Scotch , 1.9% Irish , 2.5% Dutch , 0.6% French and 5.6% German . When CPG

This information facilitated the internment of Japanese-Americans , following the Japanese attack on the U.S. at Pearl Harbor on December 7, 1941, and the internment of Italian- and German-Americans following the United States' entry into World War II . In 1980, four FBI agents went to the Census Bureau's Colorado Springs office with warrants to seize census documents, but were forced to leave with nothing. Courts upheld that no agency, including

3479-525: The minimum rounding up the quotas for all countries that would not have otherwise reached 100, in practice the annual global quota total was slightly more than 150,000 (in 1930 totaling 153,714), but the formula calculation still used the fixed number 150,000. The total number of U.S. inhabitants in 1920 with national origins in quota countries was 89,506,558 so the national origins formula f expressed mathematically as f = ⁠ n / 89,506,558 ⁠ = ⁠ q / 150,000 ⁠ , where n

3550-476: The names of the heads of household and a general demographic accounting of the remaining members of the household. Beginning in 1850, all members of the household were named on the census. The first slave schedules were also completed in 1850, with the second (and last) in 1860. Censuses of the late 19th century also included agricultural and industrial schedules to gauge the productivity of the nation's economy. Mortality schedules (taken between 1850 and 1880) captured

The 1924 Act also included the Asian Exclusion Act , which limited immigration to persons eligible for naturalization. As a result, East Asians and South Asians were effectively banned from immigrating. Africans were also subjected to severe restrictions. Immigration from North and South America

Based on the new formula, the number of new immigrants admitted fell from 805,228 in 1920 to 309,556 in 1921–22. The average annual inflow of immigrants prior to 1921 was 175,983 from Northern and Western Europe and 685,531 from other countries, mainly Southern and Eastern Europe. In 1921, there

To compute the proportions of blood each national origin had contributed to the American population as of 1920, demographers divided the population into four more easily classifiable groups by generation. The process was complicated due to the more limited set of data recorded in the country's earlier decades compared to the increasingly detailed information published in later versions of

While lower courts had ruled for an injunction against the department from implementing the Replan Schedule, the Supreme Court issued a stay of the injunction in October 2020, allowing the census to end early. Around the same time, Trump issued a memo to the Commerce Department on July 21, 2020, instructing them to use estimates of undocumented immigrants and subtract their numbers from

This census is also notable for the fact it is one of only three for which the original data are no longer available. Almost all the population schedules were destroyed following a fire in 1921. One purpose of the census is to divide the house seats by population. Furthermore, as with any Census Bureau survey,

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

It mandated non-citizens seeking to enter the US to obtain and present a visa obtained from a US embassy or consulate before arriving in the US.
