To ensure respondents had recent exposure to alcohol, the current sample was limited to 13,793 past-year drinkers (64.7% of weighted total sample), of whom 12,833 (91.8%) had data on their neighborhood of residence at the time of the survey. To allow subgroup analyses by race/ethnicity, we excluded 147 people who identified with any group other than White, Black, or Hispanic, as the other groups were too small for sub-analysis and too heterogeneous for combined analysis. The final, weighted analysis sample was 51.3% male and 80% White, 9% Black and 11% Hispanic (Table 1 ). A majority (61.6%) of Hispanics were born in the US. Approximately 33% of the sample came from each survey, with no differences in distribution across surveys by sex or race/ethnicity.Table 1Characteristics of weighted sample of past-year drinkers, 2000–2010 US National Alcohol Surveys.WomenMenWhitesBlacksHispanicsTotaln = 6,603n = 6,083n = 8,880n = 1,850n = 1,956N = 12,686High-risk drinking exceeding NIAAA recommended guidelines1, %4648.748.335.351.747.4 a, bbbAlcohol dependence symptoms, M(SD)0.27 (0.83)0.47 (1.06)0.33 (0.86)0.51 (1.44)0.57 (1.37)0.37(0.97) aaa, bbbAlcohol dependence2 , %2.65.73.56.27.34.2 aaa, bbbFamily history of alcohol problems, %aaa, bbb Negative family history46.352.150.046.645.449.2
