This study aims to determine the differences in forgiveness, hope, and satisfaction with life based on familyrelated characteristics, namely birth order, the total number of siblings, parents' marriage status, housemate, parents' age category, parents' occupation nature, and parents' education, aside from general demographic characteristics, among Indonesian senior high school age students. Participants in this study were 909 students of a vocational high school in Semarang, Indonesia obtained through cluster random sampling technique (MAge=15.93; SDAge=.909; male=60.3%; female=39.7%). Participants were asked to complete the identity including general demographic and family-related data, the Forgiveness Scale, the State Hope Scale, and the Satisfaction with Life Scale. Analyses were conducted using The Man-Whitney U and Kruskal Wallis Test. Spearman's rho and descriptive statistics were also used. The results of this study indicate that family-related characteristics have more contribution to differences in hope and satisfaction with life than forgiveness. Forgiveness was only distinguished by housemate and mother's age category. Hope was distinguished by the total number of siblings, parents' marriage status, housemate, father's occupation nature, and both parents' education. Satisfaction with life was distinguished by parents' marriage status, housemate, both parents' occupation nature, and father's education. This study also indicates how the dimensions of forgiveness and the subscales of state hope are specifically related and differentiated according to the familyrelated characteristics observed in this study. In addition, the results of this study indicate the importance of the role of gender differences, especially in the characteristics of fathers and mothers in terms of age, occupation, and education for the various differences of the variables examined in this study.
