The fascinating survey of attitudes toward homosexuality world-wide shows not only which countries say 'yes' (Canada 80%; Spain 88%, U.S. 60%) and which say 'no' (Nigeria 98%, Uganda 96%, South Korea 59%, China 57%) to the question.
The less religious a country, and the wealthier the country, the more likely it is that the country will have positive attitudes to homosexuality.
