How has the number of Muslims worldwide changed over time?

Historical Overview

Islam is the second-largest religion in the world, with an estimated 1.8 billion followers as of 2021. The religion originated in the Arabian Peninsula in the 7th century and spread rapidly throughout the Middle East, North Africa, and parts of Europe and Asia. Over time, Islam has undergone significant changes, including schisms that led to the formation of different sects and movements.

Growth Trends

The number of Muslims worldwide has been steadily increasing over time. According to Pew Research Center’s projections, by 2050, Muslims will make up nearly one-third (31%) of the global population. This growth is largely due to high fertility rates among Muslim populations in countries such as Indonesia, Pakistan, Bangladesh, Nigeria, and Egypt.

Challenges to Growth

Despite this growth trend, there are several challenges facing Islam today. One major challenge is Islamophobia – a fear or hatred towards Islam and its followers – which has increased in recent years due to terrorist attacks carried out by extremist groups claiming to act in the name of Islam. Additionally, some Muslim-majority countries have experienced political instability and conflict that have negatively impacted their populations.

Which countries have the largest Muslim populations?

Countries with Largest Muslim Populations

As of 2021, Indonesia has the largest Muslim population in the world with approximately 229 million followers. Other countries with large Muslim populations include Pakistan (200 million), India (195 million), Bangladesh (160 million), Nigeria (100 million), Egypt (90 million), Iran (85 million), Turkey (84 million), Algeria (43 million), and Morocco (37 million).

Muslim Minority Populations

While these countries have the largest Muslim populations, there are also significant Muslim minority populations in many other countries. For example, China has an estimated 23 million Muslims, Russia has approximately 14 million, and the United States has around 3.5 million.

Are there any regions where Islam is growing or declining in popularity?

Growth Regions

Islam is growing in popularity in several regions of the world. According to Pew Research Center’s projections, the Middle East and North Africa will continue to have the highest concentration of Muslims by 2050. However, sub-Saharan Africa is expected to experience the largest growth in Muslim population due to high fertility rates.

Declining Regions

On the other hand, some regions are experiencing a decline in Islam’s popularity. In Europe, for example, Muslim populations are projected to remain relatively stable over time due to low fertility rates and immigration restrictions. Additionally, some Muslim-majority countries such as Turkey and Iran have seen a decline in religiosity among their populations.

How do estimates of global Muslim populations vary between different sources and organizations?

Varying Estimates

Estimates of global Muslim populations can vary significantly between different sources and organizations due to differences in methodology and data sources. For example, Pew Research Center’s projections estimate that there were approximately 1.8 billion Muslims worldwide as of 2021, while other estimates range from 1.6 billion to over 2 billion.

Data Sources

One factor that can contribute to these discrepancies is differences in data sources used by different organizations. Some may rely on official government statistics or census data, while others may use surveys or other methods to estimate religious affiliation.


Another factor that can impact estimates is differences in methodology used by different organizations. For example, some may use a more inclusive definition of who is considered Muslim, while others may only count those who identify as such in surveys or official records. Additionally, projections can vary depending on assumptions made about future fertility rates and migration patterns.

In conclusion, the global Muslim population is estimated to be around 1.8 billion, making up approximately 24% of the world’s population.
