Women's labor force participation in Thailand, particularly in the mod
ern sector, recently has increased in conjunction with rapid declines
in fertility. This paper examines whether a relationship exists betwee
n child care considerations and fertility decision making among Bangko
k women. Although the two-child family has become the norm in recent y
ears, and although most respondents said that ideally they would like
to have two children, a high proportion of women surveyed said they pl
anned to only have one child. Women's work status and type of employme
nt is found to strongly affect the likelihood of having a second birth
: those who work at jobs that not only are low-paying but are located
in a formal setting are least likely to have a second child. The type
of child care for the first child also has an impact: those whose firs
t child is in a less preferred situation are less likely to have a sec
ond. Variables measuring the need for and type of child care are found
to have greater consequences for fertility than do usual measures of
socioeconomic status.
