2. Figure 1
Total fertility rate (TFR) conditional on maternal age, race, and year obtained from National Vital Statistics Reports via the National Center for Health Statistics [8,9]. Partial components of fertility rate are scaled 1000-fold and multiplied by the age interval (ie, 1000 ∗ πa,r,y ∗ Δa) to align their units with those of TFR. Gaps in year coverage represent unequal data collection periods for different maternal race and ethnic groups.

3. Figure 2
Probability of sibling survival conditional on age and race/ethnicity. Obtained from the National Center for Health Statistic's National Vital Statistics Reports-US Life Tables, 2008 [37]. These figures are calculated using American Community Survey population estimates by age and death certificate information relayed to the National Center for Health Statistics through the National Vital Statistics System.
