How people around the world view same-sex marriage
Among the 32 places surveyed, support for legal same-sex marriage is highest in Sweden, where 92% of adults favor it, and lowest in Nigeria, where only 2% back it.
Household size and composition often vary by religious affiliation, data from 130 countries and territories reveals. Muslims and Hindus have larger households than Christians and religious “nones,” influenced in part by regional norms.
A country-by-country analysis of data from more than 2,500 censuses, surveys and population registers finds that 84% of adults and children around the globe are religiously affiliated. The study also finds that the median age of two major groups – Muslims (23 years) and Hindus (26) – is younger than the world’s overall population (28), while Jews have the highest median age (36).
A comprehensive demographic study of more than 200 countries finds that there are 1.57 billion Muslims of all ages living in the world today, representing 23% of an estimated 2009 world population of 6.8 billion.
