Note: Percentage and mean(SD) estimates accounted for the complex survey design, and were weighted to be representative of the U.S. population. The standard error estimates for all percentages were <0.01. W/C = White/Caucasian, B/AA = Black/African American, AI/AN = American Indian/Alaska Native, A/NaH/PI = Asian/Native Hawaiian, Pacific Islander, NH = non-Hispanic.
Age of onset for drinking and time to alcohol dependence variables were Winsor-transformed for the outermost 5% of outliers.
Annual household income ranged from 0 to 21, “less than $5,000” to “$200,000 or more.” A value of 10 represented “$35,000 to $39,999”, and a value of 11 represented “$40,000 to $49,000.”
Education level ranged from 1 to 14, “no formal schooling” to “completed Master’s degree or higher graduate degree.” A value of 9 represented “completed high school/GED,” and a value of 10 represented “some college (no degree).”
