Racial/ethnic categorization included non-Hispanic White, non-Hispanic Black, Hispanic, Asian/Pacific Islander, and “Other”. The “Other” category included groups that were too small for independent analysis, such as indigenous Americans, and non-Hispanic multi-racial individuals. Race/ethnicity was determined by self-report, and categories were collapsed from more detailed categories, defined by the survey administrators, that followed the 1990 and 2000 census conventions for the NLAES and NESARC, respectively. Race/ethnicity was assessed in these surveys as a demographic variable, and for statistical weighting purposes.
