For 47 reporting areas, data were provided from the central health agency (state health departments and the health departments of DC, upstate New York, and New York City). Data from upstate New York and New York City were combined to produce totals for the state. For the other five states, data were provided from hospitals and other medical facilities. The word "state" in this report refers to both states and DC except where DC is mentioned explicitly. Wisconsin and DC reported age for those who had abortions among residents only.
Reasons for the exclusion of rates in some states are listed in the tables; the following hierarchy was used to determine whether data were excluded: (1) abortion data by age or race or birth data by Hispanic ethnicity were not reported by state; (2) <20 births or pregnancies or <1000 women were in the group; and (3) for >15% of the abortion data, age or race of the women was unknown.
DC is not included in these comparisons because it is an urban area, and pregnancy rates are generally higher in urban areas than in states.
