The 25 most conservative, intolerant, and polluted countries in the world

Expat website Movehub recently ranked the most — and least — socially liberal countries around the world.

In order to come up with their ranking, they compared three different studies from 2016 — the Social Progress Index, the Environmental Performance Index and the World Economic Forum's (WEF) Gender Gap report.

The Social Progress Index examines categories like religious and LGBT tolerance, access to clean water, press freedom and access to education, the WEF's Gender Gap report looks into gender parity in jobs and education, and the EPI focuses on things like carbon emissions and recycling.

Movehub combined the results for each country to create a comprehensive list revealing the least liberal countries in the world.

While many of the countries in this list are Middle Eastern nations struggling to cope with the impact of the Syrian refugee crisis, others are spread out all over the world, from Cambodia in Asia to the west African nation of Angola.

See the 25 most conservative, intolerant, and polluted countries in the world below:

25. Sri Lanka — Sri Lanka came 108th in the Environmental Performance Index out of 180 countries surveyed, and performed badly on personal rights, tolerance, and access to information in the Social Progress Index.

24. Algeria — Algeria was one of the worst performing countries in the WEF's Gender Gap Report, coming in 120th. It also has one of the worst scores for personal rights in the Social Progress Index, scoring just under 14 out of 100 in the report.

23. Benin — Corruption is rife in Benin, which ranks among the world's poorest countries. Adult literacy rates are poor compared to countries with a similar GDP per capita like Afghanistan, Ethiopa and Uganda, but it also performed relatively well on political freedoms, meaning it misses out on a place in the top 20.
