This research paper aimed to study the effects of birth order on an individual’s self-efficacy and life-satisfaction, within the age group of 16-30 years. Sherer’s Self-Efficacy scale was used to measure self-efficacy levels in participants and the Satisfaction with Life Scale was used to measure the levels of life-satisfaction. The purpose of this paper was to study the difference in scores on these two scales with respect to the four birth order positions considered, namely – first- born, middle-born, last-born and only child. It was found that first borns show a slightly higher level of self-efficacy, when compared with the other birth order positions. In terms of life- satisfaction, last-borns were found to score higher than the other birth order positions.
