Cost of living in Tangier (Morocco) is 30% cheaper than in Amman (Jordan)
This comparison is lacking data. It provides a decent comparison, but it is not yet reliable. It is based on 1,697 prices entered by 138 different people.
For example, to keep the same standard of living that would require Dinar 1,600 in Amman you would need to make just about Dinar 1,114 (14,438 Dirham) in Tangier.
