A Muslim-majority country is a nation where the religion of Islam is widespread. These nations are collectively known as the Muslim world or the Islamic world. There are no universal rules that identify what makes a Muslim-majority country, although many people go by the standard that a Muslim population of more than 50% constitutes a Muslim-majority nation.
According to the Pew Research Center, there are a total of 50 Muslim-majority nations in the world. However, according to World Atlas, there are 45 Islamic countries. Further data shows that these nations contribute about 8% of the world’s nominal GDP. The region with the most Muslims is the Middle East-North Africa region. Other areas with large percentages of Muslims include Central Asia, Southeast Asia, South Asia, Sub-Saharan Africa, and Asia-Oceania. There are smaller percentages living in the Americas and Europe.
