While most countries provided for the protection of religious freedom in their constitutions or laws, only a quarter of those countries were found to fully respect these legal rights in practice. In 75 countries governments limit the efforts of religious groups to proselytise and in 178 countries religious groups must register with the government. In 2013, Pew classified 30% of countries as having restrictions that tend to target religious minorities, and 61% of countries have social hostilities that tend to target religious minorities.
