Notes:

For 2024, "AGI" figures are full year estimate based on January-November figures.
For most states, CDC/state data are incomplete.
Parenthetical figures are estimates, some of which are derived from reported data.
Abortion ratios, percentages, and rates may be based on a mix of CDC/state and AGI data and thus may not represent a consistent time series.
