Extended families are the more traditional type of households in Chinese society. An extended family has to consider the diverse needs of household's members when making residential mobility decisions because there are more family members and more income resources compared to other household types. This study raises three hypotheses. The empirical study employs the binary logistic regression model and uses data from the "1990 Census of Population and Housing in Taipei, Taiwan." The results suggest that the marginal effect on mobility decisions for household head as the primary earner in the first-generation household is not significantly larger than that for the second generation household. The bargaining power coming from respected status in the household for the head in the first-generation household is not supported. Regardless of type, the age of the head being primary earner has a larger negative effect on mobility decisions than the head not being the household's primary earner. The effects on mobility decisions are significant for the household with double income resources and schoolage children when the second-generation member is the primary earner.
