As global demographics continue to shift, a new report by the renowned Pew Research Center has raised concerns over the declining number of Christian-majority countries worldwide. While demographic changes are often the subject of political debate in countries like India, this latest study presents a broader, data-driven view of how religious compositions are evolving on a global scale.

According to Pew’s findings, the number of countries with a Christian majority has decreased over the last decade. Between 2010 and 2020, the number dropped from 124 to 120. Though Christianity still represents the largest religious majority globally, this decline signals a significant trend in the world’s religious landscape.

The analysis, which surveyed 201 nations and territories, shows that as of 2020, only 60% of them had Christian-majority populations—down from 62% in 2010. One of the main drivers of this shift is the growing number of individuals leaving Christianity. Millions across the globe have disaffiliated from the religion in recent years, and many of them now identify with no religion at all.

The most notable changes have occurred in countries such as the United Kingdom, Australia, France, and Uruguay. In each of these nations, Christians no longer make up more than half the population—a marked change from a decade ago. At the same time, the share of people identifying as religiously unaffiliated has grown significantly. In 2020, ten countries had populations where the religiously unaffiliated formed the majority, compared to just seven in 2010.

Uruguay stands out as the only country in the Americas where Christians are now a minority. Around 52% of Uruguayans say they follow no religion, while Christians account for 44% of the population. In the UK, Australia, and France, no single religious group holds a clear majority anymore, though the number of non-religious individuals is approaching or surpassing that of Christians—highlighting a strong trend toward secularism.

Interestingly, while Christian-majority nations have declined, the number of Muslim-majority countries has remained stable. In both 2010 and 2020, there were 53 Muslim-majority countries. In contrast, Hindu-majority nations remain limited to just two: India and Nepal. Notably, 95% of the world’s Hindus reside in India. While Mauritius has a significant Hindu population—48%—it does not qualify as Hindu-majority.

Globally, Hindus account for about 15% of the population. The number of Buddhist-majority nations also remained unchanged at seven. Israel continues to be the only country where Jews form a majority.

Pew’s comprehensive data reflects not only religious transitions but also the broader cultural and ideological changes shaping societies in the 21st century.
