- Research Questions
- Does education have the same delaying effect on
the timing of first birth among young adults from
different racial/ethnic groups? - Does the timing of marriage mediate the
relationship between education and timing of
first birth across these racial/ethnic groups? - Previous Research
- Schooling and employment experiences are very
important in the timing and sequencing of family
formation behaviors. - Family formation varies significantly across
racial/ethnic groups. - Asians, both girls and boys, have particular low
rates of first birth before high school
graduation and particular low non-marital
fertility, compared to other racial/ethnic
groups. - Hypotheses
- Education will have a differential effect on the
timing of first birth for youths across
racial/ethnic groups. - The effect of education on the timing of first
birth will vary by the type of schooling under
consideration. High school completion will be
associated with a greater probability of first
birth and college completion will be associated
with lower probability of first birth - Marriage timing will explain some of the
racial/ethnic differences in birth timing - Racial groups have different normative paths from
school/marriage to birth

- Conclusions and Discussions
- It is not only educational attainment or marital
status per se that influence the timing of the
first birth. The timing and sequence of these
events explain much of the differences among
young adults from different racial/ethnic groups.
This effect is most salient for Asian young
adults. - Low marriage rates and high educational
attainment explain much of the delay in first
birth among Asians compared to other racial
groups. - The probability of non-marital births is
especially high among blacks but for those who
complete college, probabilities of first birth
decrease more than other groups. - The current research only captures the early life
course for young adults, many of the respondent
in this sample have not given birth yet during
the observation period so we cannot distinguish
the extent to which these are delays or family
formation forgone.
There is considerable racial/ethnic variation in
the age at family formation. Blacks are younger
at first birth and older at marriage (i.e. high
nonmarital fertility) while Asians have the
highest ages of both events (i.e. largest delays
in family formation)
