Data from the nationally representative 1994 Inter-Censal Demographic Survey are used to examine the association between family size and children's schooling in Vietnam. The data provide information on several education measures for all children over age 10, including children no longer residing in the household. Although a clear inverse bivariate association between family size and children's school attendance and educational attainment is evident, multivariate analysis controlling for urban/rural residence, region, parents' education, household wealth, and child's age, reveals that much of this association, especially that predicting educational attainment, is attributable to these other influences. Moreover, much of the effect that remains after statistical adjustment for the other influences is seen mainly at the largest family sizes. We consider the implications of these findings for current population policy in Vietnam and the possible features of the Vietnamese context that might account for the modest association.
