Global restrictions on religion

"This study examines the incidence of many specific types of government and social restrictions on religion around the world. In 75 countries (38%), for example, national or local governments limit efforts by religious groups or individuals to persuade others to join their faith. In 178 countries (90%), religious groups must register with the government for various purposes, and in 117 (59%) the registration requirements resulted in major problems for, or outright discrimination against, certain faiths. Public tensions between religious groups were reported in the vast majority (87%) of countries in the period studied (mid-2006 through mid-2008). In 126 countries (64%), these hostilities involved physical violence. In 49 countries (25%), private individuals or groups used force or the threat of force to compel adherence to religious norms. Religion-related terrorism caused casualties in 17 countries, nearly one-in-ten (9%) worldwide."
