Birth order and personality: Evidence from a representative sample of Chinese.

\n Birth order differences in personality have been studied for almost a hundred years. However, most studies have been conducted in Western cultural contexts, while few studies have addressed the associations between birth order and personality in East Asian cultural contexts. In this study, we examined how birth order influences the Big Five personality traits using a representative Chinese sample (<italic>N</italic> = 14,148). Both between- and within-family designs were used to examine the associations between birth order and the Big Five personality traits. The results indicated that the impacts of birth order on the Big Five personality traits were not statistically significant and were negligible. We conclude that birth order has no lasting impact on the Big Five personality traits in the Chinese cultural context.What factors cause children in a family to develop different personality traits? One popular belief in society is that birth order plays a significant role in shaping siblings' personality traits. Extensive research conducted by academics over the past century has explored the relationship between birth order and personality traits, but the findings remain inconclusive. It is important to note that most of the existing research has focused on Western cultural contexts. In an effort to shed light on this topic from a different cultural perspective, this study examined the impact of birth order on personality traits within the Chinese cultural context. The findings of this study indicated that birth order did not have any significant effect on Chinese personality traits. Therefore, the effect of birth order on personality traits may just be a social prejudice. [ABSTRACT FROM AUTHOR]
