The Pew Research Centre’s latest report on the global religious landscape from 2010 to 2020 reveals significant transformations in how people identify with faith, driven by rapid social and demographic changes. The global population grew from approximately 5.9 billion in 2010 to nearly 6.9 billion in 2020.
Christianity remains the largest faith, but its growth has slowed compared to global population growth. In contrast, Islam’s influence has increased, with Muslims making up 24.1% of the world’s population. Christians are more evenly distributed globally, while many Muslims are younger than 50.
Europe is experiencing a decline in religious identification, with nearly 17% of its population now considered “nones” (those who identify as religiously unaffiliated). North America has seen a modest increase in secular identities. Meanwhile, vibrant Christian movements like Pentecostalism and evangelicalism have expanded rapidly in Africa and Latin America.
A notable trend is the growth of those with no religious affiliation, particularly in developed nations. This shift poses challenges for faith institutions and policymakers about their role in public life. The report highlights the need for renewed dialogue and understanding among faith communities to address changing spiritual needs.
