Figure.. Monthly Differences in the Number of Observed vs Expected Births in Texas, January 2016-December 2022
Horizontal line at 0 indicates no difference between the observed and expected number of monthly births; dotted vertical line is March 2022, corresponding to the last birth cohort not exposed to Texas’ Senate Bill 8 that was used to generate the exposure period counterfactual; shading indicates the 95% CI in the policy exposure period. Observed birth data were from the National Center for Health Statistics. Expected birth counts and corresponding statistics were calculated using a comparative interrupted time series with an augmented synthetic control approach.
