A recent Pew Research study analyzing data from 2010 to 2020 reveals significant shifts in the global religious landscape 1 2 3. The study, drawing from over 2,700 sources across 201 countries, highlights demographic growth, changing affiliations, and rising secularism 1 3. Christianity remains the largest global religion, but Islam's growth outpaced all others during this period 1 3.
The global religious population has grown substantially, from approximately 5.9 billion in 2010 to nearly 6.9 billion in 2020 2. This increase is largely attributed to demographic trends in regions like sub-Saharan Africa, characterized by high birth rates 2 5. While the Christian population increased by 122 million, the Muslim population saw a larger increase of 327 million 1 3. Despite remaining the largest faith, Christianity's growth is not keeping pace with the overall global population increase 2 5.
A notable trend is the increasing number of people identifying as religiously unaffiliated, often called "nones" 1 2. By 2020, "nones" constituted 24.2% of the global population, making them the third-largest group after Christians and Muslims 1 3. This growth is considered "striking" given that religiously unaffiliated individuals typically have lower fertility rates 1 3. The primary driver behind this increase is people abandoning their religious identity, particularly those raised as Christians 1 3.
Sub-Saharan Africa has become the region with the largest concentration of Christians, housing 30.7% of the world's Christian population as of 2020 1 3. This marks a shift from 2010 when the majority of Christians resided in Europe 1 3. This shift is due to both population growth in sub-Saharan Africa and widespread Christian disaffiliation in Western Europe 1 3 5. While Christianity is growing in Sub-Saharan Africa, it is declining in many Western countries 5.
Fertility rates, mortality rates, migration, and religious switching all influence religious demographics 5. Religious switching, defined as changing from a childhood religion to another or becoming unaffiliated, is a significant factor 1 5. Christians and Buddhists experienced the greatest losses due to religious switching 1 3 5. High fertility rates are a major factor in the growth of the Muslim population 1.
