The variables were recorded as ordinal (O), nominal (N), continuous (C), and binary (B). The binary variables’ base option is otherwise, i.e., for K12, value 1 is for if participant has kids under 12 living in the house, 0 is otherwise
^aThe variable was recorded with seven categories (< 635€; 635€–999€; 1000€–1999€; …; 6000€ <)
^bThe items used for the summated scale variable are described in Table 9, in the Appendix
^cThe ordinal variables were analysed in the models as continuous
