Cook and Peoria counties had the highest abortion rates in Illinois in 2016, according to a report issued in December by the Illinois Department of Public Health.
The report tracks abortions performed on an annual basis, as well as the age and marital status of the abortion recipient and the pregnancy term at the time of the abortion.
Of the 30 most-populated counties in Illinois, Rock Island, with 147,514 residents, boasted the lowest abortion rate, reporting fewer than 50 abortions performed in 2016.
In contrast, Tazewell County (136,122) reported 197, and La Salle (112,994) came in at 141. Adams (county seat: Quincy), Whiteside (Morrison), Coles (Charleston) and Henry (Geneseo) also reported fewer than 50 abortions.
Cook County recorded 21,747 abortions in 2016, a per-capita rate of 0.42 percent.
Peoria had 472, a rate of 0.25 percent – more than twice the rate in Lake and McHenry counties.
Counties with fewer than 50 abortions in a year don’t report their precise number.
