Today's decision by the US Supreme Court to overturn the law of abortion is the culmination of years of efforts by Americans who oppose the procedure. The goal is to reduce the number of abortions by banning them. There have been years of abortion data across the world.

In an analysis done by the Guttmacher Institute and the World Health Organization, abortion rates were the same in countries that restricted abortion and those that allowed it.

When it comes to safety, the picture is different according to WHO. 9 out of 10 abortions are safe in countries where abortion is allowed. Only one in four abortions are safe in countries with restrictive abortion laws.

The number of maternal deaths that occurred from abortion each year in the 1960s and 1970s was cut in half by the Supreme Court decision. 20 states are likely to see a higher maternal death rate with little change in abortion rates.

The reduction of abortions is due to free contraception. The Washington University School of Medicine studied 9,000 women and found that the abortion rate decreased by more than 60 percent.

Over the last 30 years, abortion rates have been declining as contraceptive access has increased and women have been freed from poverty. Increased federal contraceptive care, increased medicare funding for abortion, and around 168 abortion restrictions or bans were passed in 25 states over the course of the next five years.
