Why American census categories for race and ethnicity are sociopolitical, not scientific, constructs

In short: The United States tracks its diverse population through evolving census categories that reflect shifting political goals rather than biological reality. From the 1790 census to modern revisions, these labels have been used to define labor forces, land rights, and social status, revealing a history of power rather than objective science.

The American census has categorized residents since 1790, when it divided people into free white individuals, other free persons, and enslaved people. Over time, these labels have functioned as tools of social control. For instance, 20th-century blood quantum laws and the one-drop rule were designed to preserve agricultural labor forces and consolidate land ownership for white populations. Anthropologists argue these distinctions were never biological; instead, they were mechanisms to enforce white hegemony and privilege by classifying mixed-race children into lower-status groups.

Today, the government treats race and ethnicity as separate concepts. Hispanic or Latino identity is considered an ethnolinguistic category rather than a race, meaning individuals of any race can identify as Hispanic. This distinction has historically caused confusion, as previous census forms forced respondents to choose a single racial category, often ignoring the complex realities of multiracial heritage. Recent efforts, such as the 2024 updates from the Office of Management and Budget, aim to improve data collection by allowing combined reporting and adding a category for Middle Eastern or North African origins.

Demographic patterns remain deeply tied to these historical and regional divisions. While White Americans constitute the majority in most states, they are a minority in regions like the West. Conversely, the South remains home to over half of the African American population, while the West hosts a plurality of many other groups, including Asian Americans and Native Hawaiians. As group boundaries become increasingly fluid, the census continues to struggle with the challenge of capturing a population that is more diverse and multiracial than its rigid, historical categories were ever designed to accommodate.
