As global religious landscapes shift, Protestant churches are witnessing varied trends of growth and decline, with Western countries, particularly the United Kingdom, standing out as regions of concern. Recent findings from the Pew Research Center shed light on the evolving dynamics of religious affiliation worldwide.
Surveys performed in 24 countries in 2024 reveal how “religious switching,” the process of individuals changing from the faith they were raised in to another, is significantly influencing Christianity’s global presence.
In the UK, Protestantism is notably impacted by this trend, experiencing more departures than new adherents. Pew’s data shows that while approximately 51% of UK adults were raised as Protestants, only about 28% continue to identify with the faith in adulthood.
Conversely, around 23% of those brought up in the Protestant tradition have left, while a mere 3% have joined as adults. This trend is consistent with findings from countries like Sweden and Germany, which also report substantial net losses in Protestant populations.
Throughout the study, former Protestants represent at least 10% of the population in nine of the 24 countries, emphasizing a significant shift away from Protestantism.
A major factor contributing to this trend is the increase in religious disaffiliation. Many who grew up in Protestant households are not converting to other religions but are choosing to identify as religiously unaffiliated. This reflects a broader pattern of secularization affecting Western societies.
Pew notes, “Adults who leave Protestantism tend to become religiously unaffiliated.”
Australia follows a similar pattern, with 15% of adults being former Protestants now identifying as religiously unaffiliated, while only about 1% have converted to Catholicism or other religions.
Despite these declines, Protestantism is not uniformly losing ground. In regions like Latin America, it is gaining traction through conversions. Brazil is a prime example, where 15% of adults have embraced Protestantism after being raised in other faiths, compared to 6% who have left, resulting in a net increase of 9 percentage points. Most converts to Protestantism in Brazil were previously Catholic.
Globally, Protestantism maintains a more balanced pattern compared to other Christian denominations, with gains in certain areas counterbalancing losses elsewhere. However, in most surveyed countries—16 out of 24—Protestants constitute no more than about 25% of the population.
Only Ghana (62%) and Kenya (55%) have Protestant majorities, highlighting the contrast with Catholicism, which faces widespread losses due to religious switching across most studied countries.
In 12 of the 24 countries analyzed, a majority of the population was raised Catholic, with percentages ranging from 59% in Hungary to 96% in Poland. While many remain in the Church, such as 92% of Polish adults identifying as lifelong Catholics, significant numbers have departed.
Former Catholics make up at least 10% of the population in 15 of the surveyed countries, despite Catholics still forming a majority in 8 of the 24 places studied.
In aggregate, Catholicism recorded a net decline due to religious switching in 21 of the 24 countries. Italy exemplifies this trend, with 22% of adults reporting they were raised Catholic but no longer belong to the denomination, compared to just 1% who converted to Catholicism.
This results in a net decline of 21 percentage points attributed to religious switching. Hungary stands out as an exception, with Catholicism showing a net gain, as 5% joined the Church and 2% left.
Meanwhile, in Kenya and South Korea, the rates of entry and exit are roughly balanced.
In Europe and parts of Latin America, many former Catholics transition to being religiously unaffiliated, joining the growing demographic of people identifying as atheist, agnostic, or having no specific religion.
Chile is a clear example, where nearly 19% of adults raised Catholic now report having no religious affiliation.
In other regions, such as Nigeria, Brazil, Ghana, and the Philippines, those departing Catholicism frequently join Protestant denominations, contributing to Protestant growth in these areas.
