Faith in Flux: The Great Drift Away – Why So Many in the UK Are Leaving Their Christian Upbringing Behind

A startling new study has revealed a quiet crisis of faith across Britain, with nearly 60% of those raised in Christian families no longer identifying with the religion of their childhood. The Pew Research Centre’s report paints a sobering picture: 58% of UK adults who grew up attending church now consider themselves atheist, agnostic, or followers of other faiths. While church attendance saw a modest 4.5% uptick in 2023—rising to 693,000 weekly worshippers—the numbers remain a shadow of past generations, when 1.6 million Britons filled pews every Sunday in the 1960s.
The trend isn’t unique to the UK. Across 27 nations surveyed, Western countries like the Netherlands, Sweden, France, and Spain showed similar declines, with more people abandoning Christianity than embracing it. Spain stood out as the country with the highest proportional loss of believers. Meanwhile, nations such as the Philippines, Hungary, and Nigeria bucked the trend, retaining nearly all of their Christian-raised populations. The most dramatic drop, however, came from an unexpected corner: South Korea, where only 51% of those raised Christian still hold to the faith—the lowest retention rate in the study.
What’s behind the great drift away? Sociologists point to secularization, changing cultural values, and a lack of engagement among younger generations. Yet, as churches in the West grapple with dwindling numbers, the data raises deeper questions about belief, identity, and what it takes to sustain faith in an increasingly disconnected world. For Britain and much of Europe, the challenge is clear: how to reignite a spiritual legacy that once defined nations—but now, for many, feels like a relic of the past.
