Birth registration formed a key part of the administration of white supremacy between Reconstruction and World War II. In the allotment of Indigenous lands and the enforcement of de jure segregation by states, birth registration served an important ideological and administrative function. Because allotment policy combined property transmission with family reorganization, it made documentation of identity more important to the federal Indian Office. The Office imposed nuclear family structures on complex kin networks to establish access to land title, and it used documentation to alter family relationships to fit with American property law. During the same years, southern states used birth registration to fix racial identity in order to determine access to school, marriage, and many other benefits. Racial classification through birth registration, in other words, worked less to record the truth than to help produce it.

In 1998, the Canadian historian and politician Michael Ignatieff wrote: “All nations depend on forgetting: on forging myths of unity and identity that allow a society to forget its founding crimes, its hidden injuries and divisions, its unhealed wounds.” Ironically, Ignatieff's home country has belied his assertion. Canada has engaged in collective remembering of one of its hidden injuries—the Indian residential schools—through a Truth and Reconciliation Commission (TRC) from 2009 to 2015. Australia, too, has reckoned since the 1990s with its own unhealed wounds—the separation of Aboriginal and Torres Strait Islander children from their families, or, in common parlance, the “Stolen Generations.”
