Description

Definition
This variable codes race responses into a simple, historically compatible scheme across US samples, assigning a single race to multiple-race people. The full detail available for responses to the race question is preserved in the race (US00A431) variable. The detailed categories (2 digits) mostly consist of national origin groups.

In the 1900 US sample, we have single-race responses, implying that the relationship with race is a straightforward data translation.
