The N2HH adult and youth data list presents each variable code for both the adult and youth questionnaires, along with the SPSS label for the variable. The list also indicates whether the variable item is in both questionnaires or only in the adult or the youth questionnaire. The variable number corresponding with the question number in each questionnaire is also indicated. There are 4,447 variables for adults and 2,593 variables for youth. Data descriptive statistics derived from the adult questionnaire show the "valid N," minimum, maximum, and standard deviation; and order number for each variable addressed in the adult questionnaire. The same information is provided for N2HH youth data descriptive statistics.
