Abstract: This paper investigates the role that children play in the migration decisions of Chinese women. The presence of children of various ages is hypothesized to affect the timing of migration, the length of migration, and the nature of migration in terms of who goes along. In addition, we also investigate whether the sex of the children affects migration decisions. Results indicate that whether one's husband ever migrated has a positive effect on migrating before childbirth. Return timing is strongly linked to the age of the child. Many mothers return to rural areas around the time that the child begins formal schooling. We also find that women who have given birth to a boy are significantly less likely to migrate after childbirth but more likely to take the boy with her if she does migrate.
