Definition of table data (see notes after table for additional information):

• Live births includes data from the Centers for Disease Control and from state health departments.
• Abortions, reported includes data from the Centers for Disease Control and from state health departments.
• Abortions includes estimates from Alan Guttmacher Institute surveys.
• Abortions, merged combines official reported data and Guttmacher figures with the compiler's estimates (provisional).
• Fetal deaths generally includes fetal deaths or stillbirths of at least 20 weeks` gestation.
• Abortion ratio is abortions per 1000 live births.
• Abortion % is abortions as percentage of pregnancies (excluding fetal deaths/miscarriages).
• Abortion rate is abortions per 1000 women ages 15-44.
• Abortion %, merged is abortions as percentage of pregnancies, using the abortions, merged figures (provisional).
• Abortion rate, merged is abortion per 1000 women ages 15-44, using the abortions, merged figures (provisional).

Notes:

• For most states, CDC/state data is 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.
