Most of the world has some sort of religious restrictions, according to a new study by the Pew Research Center.

Nearly a third of all countries with some having large populations, either have laws that restrict religion or citizens who harm people of other faiths.

As a result, the religious oppression actually affects more than 70 percent of the world's population.

Countries most affected include China, India, Iran, Saudi Arabia, and Indonesia. Those with the most religious freedom include the United States, Britain, Brazil, and Italy.

The study found that religious minorities suffer the brunt of the intolerance.
