Predicted probabilities of having extra-couple sexual intercourse (a), occasional sex (b), and numerous sexual partners (c) by gender and place of birth. Percentage values and 95% confidence intervals. Control variables: Had first sexual intercourse before age 16? Ever got drunk? Ever used marijuana or ecstasy? Ever drove fast? Had difficulty in following parents’ rules at age 16–18? Had difficulty in following high-school’s rules? dimension of municipality; age at interview; at least one older sibling alive; current value of religion; separated/divorced parents; death of at least one parent; at least one parent has a diploma or higher educational level; at least one parent is employed at a middle-high qualified level; talk with at least one parent about affective experiences (16–18). The setting is the null hypothesis that all control variables, save for the constant term, are equal to zero (i.e. the reference category showed in Table 2). Values (and significance) of marginal effects depend on this setting (Greene, 2009). Source: our elaborations on SELFY data
