Overall, the figures in the 2012 survey suggest that the percentage of Muslims in the countries surveyed who approve the death penalty for Muslims who leave Islam to become an atheist or convert to another religion varies widely, from 0.4% (in Kazakhstan) to 78.2% (in Afghanistan). The Governments of the Gulf Cooperation Council (Saudi Arabia, UAE, Oman, Qatar, Bahrain and Kuwait) did not permit Pew Research to survey nationwide public opinion on apostasy in 2010 or 2012. The survey also did not include China, India, Syria, or West African countries such as Nigeria.
