Do birds of a feather flock together in China?

Evidence of couple similarity was examined in 2 nationally representative samples (Ns = 536 and 537 couples) from mainland China. Variable-centered and couple-centered tests provided convergent results suggesting that husbands and wives were considerably similar on characteristics of 3 broad categories: demographic variables, values, and personality. Additional tests suggest that value and personality similarities were not likely to be due to social homogamy, convergence, response biases, or culture-unique characteristics. Whereas the couple similarity on demographics and values largely mirrors what has been observed in Western research, Chinese couples' consistent and strong similarity on personality domains presents a striking contrast to Western couples who share little systematic similarity on personality.
