According to Numbeo, Tunisia, Algeria, and Libya are the most affordable countries for bread, with Tunisia having the lowest price at $0.14 per 500g. This affordability is largely due to the subsidization of bread prices by many Arab countries, including Egypt, Morocco, and Turkey, which are among the top ten most affordable countries for bread. The high cost of bread is observed in the United States and northern European countries like Switzerland, Iceland, Norway, and Denmark.
