US abortion rates have declined significantly for nearly 40 years. Reported abortions increased from near zero through 1967 to 1.5M in 1979 and a peak of 1.6M in 1990, before declining to one-third of that level by 2018. The abortion rate per 1,000 child-bearing women reached 16.3 in 1973 when the US Supreme Court issued its Roe vs. Wade ruling. The rate peaked at nearly twice as high in 1981 at 29.3. The rate fell back to the 1973 level by 2012 and has fallen 20% further in recent years to 13.5.
