The main purpose of this study was to examine if there is sex favoritism toward boys over girls for parents and if there is any difference between boys and girls in parental educational concern and expectation toward them. Subjects were 1167 sixth-graders, (boys, n=584; girls, n=583) randomly selected from 20 schools in Taipei City, using stratified cluster random sampling. The results were found as follows: Although the numbers of children in families has been successfully decreased by the Family Planning Program, there were more boys than girls when parents had only one child. For boys and girls, parents had similar educational expectation toward them. However, parents paid more educational concern to boys than girls. These findings may suggest the tradition of parents prefering boys to girls still exists in the current society.
