Сonsensual sex between adults, including incest, is not a crime in:
Argentina
Brazil
USA New Jersey
China (except Hong Kong and Macau)
India
Japan
Thailand
France
Spain
Benelux
Portugal
Italy (Incest is illegal in Italy only if it provokes public scandal, according to Article 564 of the Penal code)
Estonia
Latvia
Lithuania
Russia
Sweden (Half-siblings can marry, but require special approval by the government.)
Australia
It seems like it's legal for the most of the Earth population.
Edit: I stand corrected - all those countries have appr. 3.56 billions of population while world population is 7.6 billions as of now. But it close enough to 50% I guess.
