1. Excludes households who primarily drink bottled water.
Note: The descriptive statistics are computed using survey weights. Invalid responses are not included. All variables, except family size, are in dichotomous form, meaning that the variable takes a value of 1 if the attribute is observed and 0 otherwise. "Reference group" indicates the category that is omitted in the logistic regression and thus the estimated odds ratios are to be compared to the status of the reference group. Family size is the number of family members at the time of the survey. The dummy variables for age of household members indicate the presence of one or more household members in that age class – thus, the variables are not a set of mutually exclusive dummies and no reference group is indicated.
