The varying ways in which the U.S. government has counted Americans over time offer a glimpse into the country’s past, from the days of slavery to the waves of immigrants who arrived on its shores over the centuries. Racial categories, which have been included on every U.S. census since the first one in 1790, have changed from decade to decade, reflecting the politics and science of the times.
It was not until 1960 that people could select their own race. Prior to that, an individual’s race was determined by census takers, known as enumerators. And it was not until 2000 that Americans could choose more than one race to describe themselves, allowing for an estimate of the nation’s multiracial population. These changes continue today, as major revisions of the race question are being considered for the 2020 census.
The U.S. has revised how it categorizes people who are both racially black and white more than any other group, given the nation’s history of slavery and changes in the social and political thinking across time. In the mid-nineteenth century, for example, some race scientists theorized that multiracial children of black and white parents were genetically inferior, and sought statistical evidence in the form of census data to back up their theories.
Throughout most of the history of the census, someone who was both white and another race was counted as the non-white race. In the 1850 census, enumerators were instructed to record blacks, mulattos (generally defined as someone who is black and at least one other race), black slaves, and mulatto slaves separately. In 1890, the racial categories of “quadroon” (defined as one-fourth black blood) and “octoroon” (one-eighth or any trace of black blood) were introduced. In 1930, for example, the “one-drop rule” included in enumerator instructions said that “a person of mixed White and Negro blood was to be returned as Negro, no matter how small the percentage of Negro blood.”
American Indians were not identified as such until 1860, when the racial category of “Indian” was added. Beginning in 1890, the census included a complete count of American Indians on tribal land and reservations. In 1960, categories for Aleut and Eskimo were added in Alaska only. Since 2000, the category has grouped both of these together as “American Indian or Alaska Native,” and the census form provides a blank space to specify a tribe.
The first racial category for Asians was introduced nationwide in 1870 with “Chinese,” reflecting increased concern over immigration as many people came from China to work on the Central Pacific Railroad. In 1910, “Other” was offered as a race category for the first time, but the vast majority of those who selected it were Korean, Filipino and Asian Indian. “Other” or “Some other race” was included on most subsequent questionnaires, encompassing a broader range of races, and the Asian racial categories were later expanded. Asian Indians were called “Hindus” on the census form from 1920 to 1940, regardless of religion. Beginning in 2000, people could select from among six different Asian groups in addition to “Other Asian,” with the option to write in a specific group.
In various censuses between 1960 and 1990, the categories of Hawaiian, Part Hawaiian, Samoan and Guamanian were added and counted with the totals for the Asian population. In 2000 and 2010, based on research conducted by the Census Bureau and new Office of Management and Budget guidelines, Native Hawaiian, Samoan and Guamanian became part of a new category: Pacific Islander.
Mexicans were counted as their own race in 1930 for the first and only time. Hispanic groups of any kind were not offered as options again until 40 years later, when the census form began asking about Hispanic origin as a separate question from race. Today, the form offers three Hispanic origin categories as ethnicities, along with “Another Hispanic, Latino, or Spanish origin,” with the option to write in a specific origin.
But how the census counts Hispanics could change again. In 2010, the Census Bureau began testing a question that combined the race and ethnicity questions into one, allowing Hispanics to select Hispanic as their race or origin. Other changes to the race question, such as offering more examples of the origins that fall under each racial/ethnic category, could also take effect in the 2020 census. That census will also drop the word “Negro” from what had been the “Black, African American, or Negro” response option.
