The aim of this study was to examine the impact birth order has on personality and satisfaction with life between two generations, millennials (18-39 years of age) and generation X (40+ years of age). Participants (n = 101) completed a survey which included two questionnaires, The Big Five Inventory and The Satisfaction With Life Scale. Analysis of the data found that there was no significant difference between birth order and the psychological variables that were examined. It was found that extraversion, agreeableness and conscientiousness positively correlated with satisfaction with life and neuroticism negatively correlated with satisfaction with life. No age differences were found in relation to satisfaction with life. Future research on the topic of birthorder could consider the environmental factors that impact on development along with these variables in order to find more definitive results.
