The present study was conducted among 265 Mizo samples to determine the effect of birth order on personality. Primarily, the history of research into birth order as a determinant of personality was discussed and critically analyzed. Then, other possible underlying factors such as the family dynamics and pre-dispositions which may influence personality such as gender, family size and socio-economic status were also included in the discussion. Adler’s birth order theory was tested using data from a survey of 265 Mizo individuals and examined for the effect of birth order on personality traits as measured by the NEO-FFI. Significant main effects were found only for gender on conscientiousness, socioeconomic status on, extraversion and conscientiousness while no significant two-way interaction effects of the demographic variables were found for the personality traits. A significant three-way interaction effect was found between gender, family size and birth order only on the personality domain of conscientiousness. The limitations and suggestions for improvement of the study are also discussed.
