Purpose: The purpose of this study was to compare the personality characteristics of single-child, two-child and multiple-child students in Sari. Methodology: This study was a descriptive-comparative study. The statistical population of this study included all male and female students of first, second and third grade high schools of public and private schools in Sari in the academic year of 2018-19. The sample of the study population was 370 people using random sampling method based on Morgan table. In order to predict the decrease of subjects, the tests were performed on 500 people, but finally 324 questionnaires were completed. Demographic and personality questionnaires were completed by the 5-item Neo. Data was analyzed by SPSS software using descriptive statistics and multivariate analysis of variance at the significant level of 0.05. Findings: The results showed that there was a significant difference between the characteristics of neuroticism, extraversion, openness, agreeableness, and conscientiousness of students belonging to single-parent, two-parent and multi-child families (p <0.05). Also, no significant gender differences were found among the five personality traits of male and female students of single, two and multiple children (p <0.05). Conclusion: Student personality traits of single-child, two-child and multiple-child families. Happiness, life satisfaction and hope for the future are higher in single-parent families than single-parent families. In the present study, the agreement and extraversion of single children were higher than two children and multi children. Extraversion also includes traits such as positive thinking, happiness, life satisfaction and hope for the future. To illustrate this incongruity, it can be stated that single children in their families do not have conflicts with their peers and always remain in the strong position of the first child who has no successor and who has not been affected by the birth of the next child. Cause higher extravasation of this stratum.
