Key findings: How living arrangements vary by religious affiliation around the world
Globally, Muslims live in the biggest households, followed by Hindus, Christians, Buddhists, Jews and the religiously unaffiliated.
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.
Concentrated in Europe, Orthodox Christians have declined as share of the global Christian population, from 20% in 1910 to 12% today. But the Ethiopian community is highly observant and growing.
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).
Between mid-2009 and mid-2010, religious restrictions rose not only in countries that began the year with high or very high restrictions, such as Indonesia and Nigeria, but also in many countries that began with low or moderate restrictions, such as Switzerland and the United States. The report looks at restrictions due to government actions as well as acts of violence and intimidation by private individuals, organizations and social groups.
The world’s Muslims are united in their belief in God and the Prophet Muhammad and are bound together by such religious practices as fasting during Ramadan and almsgiving to assist the needy. But they have widely differing views about other aspects of their faith, including how important religion is to their lives, who counts as a Muslim and what practices are acceptable in Islam.
