An Islamic world map is easiest to read when population size, Muslim-majority status, regional distribution and OIC membership are treated as separate layers. A country can have a very large Muslim population without being Muslim-majority, and an OIC member state is not always the same thing as a demographic category.

The main takeaway is that the Muslim world is not limited to the Middle East. The largest Muslim populations are in Asia, while Africa, Europe and the Americas each matter for demography, migration, public policy and religious life.

What this map is for

A useful Islamic world map has to separate three layers: where the largest Muslim populations live, where Muslims are the majority, and which states belong to political bodies such as the Organisation of Islamic Cooperation.

  • Population size answers "where do most Muslims live?" Indonesia, Pakistan, India and Bangladesh matter because of scale.
  • Population share answers "which countries are Muslim-majority?" Smaller countries can have a very high Muslim share without ranking high by total population.
  • OIC membership is political and diplomatic. It overlaps with the Muslim world but is not the same as a religious-demographic map.
  • Diaspora communities in Europe and North America are smaller by share but important for media, migration and public policy discussions.

Regional reading guide

The map should be read by region before comparing countries. Asia-Pacific contains the largest number of Muslims; the Middle East and North Africa contains many Muslim-majority states; Sub-Saharan Africa has some of the fastest-growing Muslim populations; Europe and the Americas are mostly diaspora or minority contexts.

  • Asia-Pacific: Indonesia, Pakistan, India and Bangladesh make the region central to any global Muslim population map.
  • Middle East and North Africa: high Muslim shares, many Arabic-speaking countries, and major holy sites and institutions.
  • Sub-Saharan Africa: Nigeria, Sudan, Ethiopia, Niger, Mali and Senegal show why Africa cannot be treated as marginal to Muslim demographics.
  • Europe, Russia and North America: lower shares, but important communities in France, Germany, the United Kingdom, Russia, Canada and the United States.

How to use the numbers

Religious-demographic data is estimated from censuses, surveys and demographic models. Treat exact country counts as approximate, compare sources when precision matters, and prefer update dates over undated viral maps.

  • For global trend questions, start with Pew Research Center because it documents religious composition by country and decade.
  • For current quick estimates by country, use a current ranking table but check whether it explains ranges and uncertainty.
  • For membership questions, use the OIC member-state list rather than a demographic table.

FAQ

Which country has the largest Muslim population?

Indonesia is generally listed as the country with the largest Muslim population, followed by Pakistan, India and Bangladesh in current public ranking tables.

Is the Islamic world the same as the Arab world?

No. Many Muslims are not Arab, and the largest Muslim populations are in Asia. The Arab world is important, but it is only one part of the Muslim world.

Is every OIC member country Muslim-majority?

No. OIC membership is diplomatic and political. It includes many Muslim-majority countries, but the membership list should not be treated as a pure demographic map.

Why do estimates differ between sources?

Religious identity can be measured by census, survey, administrative data or modelled estimates. Countries also update population data at different times.
