I’ve summarised the data by region below.
4% of countries do not allow an abortion in any circumstance, even to save the mother’s life. They are Malta, the Holy See (which to be fair has few pregnant women), Chile, the Dominican Republic and Nicaragua.
96% allow abortion to save the mother’s life.
Only 67% of countries allow abortion to prevent physical harm to the mother and 64% to prevent mental harm.
If the mother was raped, or it was incest, then that is lawful reason for an abortion in only 52% of countries. Foetal impairment is also a legal ground in only 52% of cases.
36% of countries allow abortion for economic or social reasons and 30% have abortion legally available on demand or request. The region with the most liberal abortion laws is Europe and Africa has the least. Oceania is low also, but in NZ we effectively have abortion on request – but not as a legal right.
