This study investigated whether the subjective well-being of eighth grade students varies with specific individual characteristics, individual circumstances and familial characteristics. The study population was comprised of 408 students (206 girls, 202 boys) who were in the eighth grade in the academic year 2014-2015 in Malatya in Turkey. Data was collected using a "Personal Information Form," the "Daily Hassles Scale" and the "Subjective Well Being" (SWB). T-Tests were used to describe students' demographic characteristics by gender, ANOVA to describe the relationship between SWB and students' demographic and family characteristics, and Stepwise regression to describe how daily hassles predict subject well being. There was a significant relationship between students' pocket money and academic achievements and their subjective well-being; no relationship was observed between their gender, parents' income or educational level and the number of siblings they had and their SWB . Students' problems with family, educational life and their wider environment had a significant influence on their SWB. The results of the research were discussed in accordance with the relevant literature and the suggestions were offered.
