Since the freedom of religion has decreased since 2008, let’s see how beliefs themselves relate to freedom. Again, people living in the least religious countries are the freest, and those living in Islamic countries are the least free. There is a tiny nuance, that Christianity and “No religion” is the most common pair of significant beliefs in a country, so, they’re quite related. However, the second most common pair is Christianity and Islam.
What: Average Human Freedom Index by belief. It was calculated only for those countries where followers of a particular belief make more than 10% of the population and it was weighted by that percentage. Judaism and “Other beliefs” were excluded because they had only 1 country complying with such criteria.
When: 2016 for Freedom 2020 for religion (it’s an estimate) because the latest actual data were of 2010.
Where: 147 countries of the world.
