Share of people believing in God in France 1947-2026

Do you believe in God?

For nearly eighty years, pollsters have asked the French a deceptively simple question: do you personally believe in God? The long-running IFOP survey series shows the answer changing dramatically. In 1947, two-thirds of the country, 66%, said yes. By 2026 that figure has fallen to around 40%, meaning a clear majority of French people, roughly 60%, now describe themselves as non-believers or agnostic. This steady erosion of belief is one of the defining social trends of modern France, a country that combines a deep Catholic heritage with one of the world's strongest traditions of secularism. The same retreat of faith shows up in everyday religious objects, as our analysis of French Bible owners by declared religion makes clear.

What stands out is not just the scale of the decline but its consistency. Apart from minor fluctuations, the trend has pointed in one direction for generations: 55% still believed in God in 2004, 49% in 2021, 44% in 2023, and just 41% in 2025. Belief has not collapsed overnight; it has drained away slowly, generation by generation, as older believers are replaced by younger, more secular cohorts. This pattern mirrors the broader decline of Christian identification in France, set out in our population distribution by religion in France analysis, where Christians are forecast to lose their majority entirely in the coming decades.

It is worth being clear about what these numbers do and do not measure. The survey records self-declared belief in God, not church attendance, religious affiliation or practice, which decline even faster. The figures come from representative samples of around one to two thousand adults, with the question worded identically over time, which makes the series unusually comparable across decades. The 2026 figure reflects the latest available wave and the continuation of the trend rather than a brand-new reading, and the years plotted are not evenly spaced. With those caveats noted, the direction and magnitude of the change are beyond doubt, and they place France among the most secular societies in the Western world. Indeed, on belief in God, France now ranks among the least religious countries in Europe, broadly comparable to the Czech Republic, the Netherlands and the Nordic nations.

Belief in God in France by Year, 1947 to 2026

The table lays the decline out year by year and reveals a clear tipping point. As late as 2011, a majority of French people, 56%, still said they believed in God. Within a decade that majority had vanished: by 2021 believers had slipped to 49% and non-believers had edged ahead at 51%. The crossover, when France became a majority non-believing country for the first time in the survey's history, is the single most symbolic moment in the whole series. The pace of change since then has been rapid, with belief falling a further eight points by 2025. France has travelled further down this road than most of its neighbours, though the wider continental picture, explored in our religion in Europe analysis, shows it is far from alone.

The Great Crossover: When Non-Believers Overtook Believers

Plotting believers and non-believers on the same chart turns the trend into a story with a clear turning point. In 1947 the two groups were worlds apart, with 66% believing and only 34% not. Over the following decades the believing line drifted downward while the non-believing line rose to meet it, until the two crossed somewhere around the late 2010s. By 2026 the positions have fully reversed, with roughly 60% not believing and 40% believing, almost a mirror image of 1947. This crossover is the clearest single illustration of secularisation in France, and it echoes the loss of Christian majorities seen elsewhere in our UK belief in God analysis.

The symmetry of the crossover is striking. The country has not simply become slightly less religious; it has flipped from a clear majority of believers to a clear majority of non-believers within a single lifetime. Importantly, the rise in non-belief is driven by disaffiliation rather than by a switch to other religions, the same dynamic that is reshaping the country's overall religious make-up. As the lines continue to diverge, France is settling into a new normal in which doubt and indifference, rather than faith, define the mainstream. The broader sweep of how faith is changing worldwide, against which France stands out, is covered in our world religions analysis.

Belief in God in France by Age: A Generational Divide

Age is one of the strongest predictors of belief in God in France, and the gap between generations is stark. In the most recent breakdowns, only about 36% of those aged 18 to 24 say they believe, compared with around 50% of people aged 65 and over. Belief rises steadily across the age bands, with the middle-aged sitting between the two extremes. This generational divide matters enormously for the future, because it means the decline is partly built in: as older, more religious cohorts pass on and are replaced by younger, more secular ones, the national average will keep falling even if no individual changes their mind. The same age gradient appears in religious identity more broadly across our religion in England and Wales analysis.

The age pattern also explains why the decline has accelerated in recent years. The cohorts now reaching adulthood are the least religious France has ever produced, having grown up in an overwhelmingly secular environment where active faith is the exception rather than the rule. Because belief tends to be formed early and to persist through life, these low youth figures are likely to follow each generation as it ages, dragging the national average down for decades to come. Far from being a temporary dip, the generational gap is the engine of long-term secularisation, ensuring that even a stabilisation among older believers cannot halt the broader slide. In practical terms, the country is unlikely to see any revival of belief unless attitudes among the young shift sharply, which current data give little reason to expect. This momentum is one reason demographers project continued decline in Christian identification across France.

Belief in God by Religious Commitment in France

Belief in God in France is not evenly spread; it is concentrated overwhelmingly among the religiously committed. Among practising Catholics, belief is near-universal at around 94%, more than double the national average of 44%. By contrast, among the large and growing share of French people who report no religion, belief in any god is marginal, on the order of one in ten. This concentration means that the national average is held up almost entirely by a committed minority, while the secular majority pulls it down. The strength of belief inside active Catholic communities sits in sharp contrast to the wider trend, and connects to the data in our Catholic population in Germany analysis on how committed Catholic populations compare across Europe.

The gap between practising Catholics and the unaffiliated underlines that France is not so much losing faith uniformly as splitting into two worlds. On one side sits a shrinking core of committed believers, mostly practising Catholics and members of other active faith communities, among whom belief in God remains the norm. On the other sits a secular majority for whom God has become a distant or rejected idea. This polarisation, rather than a uniform fading, is the real texture of French secularisation, and it mirrors patterns seen among committed Protestant communities in our evangelical church members in Germany analysis, where active believers retain strong faith even as the surrounding society turns away.

Religion Becomes a Private Matter in France

Beyond belief itself, the IFOP data show that the French are increasingly reluctant even to talk about religion. The share who discuss their beliefs with family at least occasionally fell from 58% in 2009 to just 38% in 2021, a drop of twenty points in barely over a decade. Conversations about faith with friends fell even faster, from 49% to 29%. Religion, once a normal part of public and family life, has retreated into a private and often unspoken sphere. This growing silence around belief is both a symptom and a cause of decline, since faith that is never discussed is harder to pass on to the next generation.

The retreat of religion into private life has wider consequences for how faith is transmitted. When belief is rarely voiced, even within families, children grow up with fewer cues that religion matters, accelerating the generational decline visible elsewhere in the data. The pattern also reflects France's distinctive culture of laicite, the strict separation of religion and public life, which encourages people to treat belief as a personal affair best kept out of conversation. The institutional side of this retreat, including the financial weakening of established churches, is visible in our Catholic Church tax revenue in Germany analysis, where falling engagement translates directly into shrinking resources.

Why Major Events Have Not Revived French Faith

It is often assumed that dramatic events, crises, disasters or moments of collective emotion, can rekindle religious feeling. The French data suggest otherwise. When asked whether the Covid health crisis had brought them closer to religion, a striking 91% said no. Similarly, 79% reported that the devastating 2019 fire at Notre-Dame cathedral, an event that gripped the nation and the world, awakened no spiritual feelings in them. These findings show just how deeply secular attitudes have become embedded: even powerful, faith-adjacent events fail to move the needle on personal belief, which continues its steady decline regardless of the headlines.

The resilience of secular attitudes in the face of such events is itself revealing. In earlier eras, war, plague or national tragedy often produced surges in religious observance; in contemporary France, they barely register. This suggests that secularisation is not a fragile mood that a crisis could reverse, but a deep, structural feature of modern French society, rooted in education, culture and generational change. For religious institutions hoping that hardship might draw people back, the data offer little comfort. The same disconnection from organised faith underlies the low rates of Bible ownership and reading, and the steady fall in Christian identification, that run through every recent survey of religion in France.

Do the French Still See Value in Religion?

Declining belief does not mean the French have turned entirely against religion. The survey reveals a more nuanced picture in which many non-believers still recognise religion's social value. About 68% of French people think religions can pass positive values, such as respect, tolerance and generosity, on to young people. Around 54% consider all religions to be equal, and 47% believe religions can contribute positively to major societal debates on issues like bioethics and the economy. This suggests that even as personal faith fades, a residual respect for religion as a moral and cultural force persists across much of the population, including among those who no longer believe in God themselves.

This gap between private disbelief and public respect is a defining feature of French attitudes to religion. Many French people treat religion much as they might treat a cultural tradition: something they personally do not practise but still see as broadly positive, especially for instilling values in the young. That said, this goodwill is passive rather than active; it does not translate into belief, attendance or transmission, which is why it coexists comfortably with relentless decline. The pattern resembles attitudes elsewhere in historically Catholic Europe, as our non-Catholic believers in Spain analysis shows, where cultural attachment to religion outlasts personal conviction by a wide margin.

Key Milestones in the Decline of Belief in France

Picking out a few landmark years makes the scale of change easy to grasp. In 1947, just after the Second World War, belief in God stood at 66%, the high point of the modern series. By 2004 it had eased to 55%, still a clear majority but noticeably lower. The symbolic break came around 2021, when belief fell to 49% and non-believers became the majority. By 2025 the figure had dropped to 41%, with the latest readings around 40%. Each milestone marks another step in a journey from a broadly believing society to a broadly secular one, compressed into the span of a single long lifetime.

Set against the long view, these milestones tell a remarkably orderly story. There is no single dramatic rupture, no moment when faith suddenly fell off a cliff; instead there is a steady, almost linear descent, punctuated only by minor wobbles. That orderliness is precisely what makes the trend so significant, because it reflects deep structural forces rather than passing events. The relentless regularity of the decline also makes the future relatively predictable: barring an unprecedented reversal, belief in God in France is likely to keep falling as the generational turnover continues, pushing the country ever further into the ranks of the world's most secular societies, alongside the smaller and more varied religious landscapes seen in our religious communities in Finland analysis.

Belief in God in France Today: A Majority Now Doubt

Standing back from the long series, the picture of France in 2026 is clear: a majority of the country no longer believes in God. Around 40% say they do, while roughly 60% identify as non-believers, atheists or agnostics. This makes France one of the most secular nations in the Western world, a status that would have seemed unthinkable to the believing majority of 1947. The shift is not merely statistical; it reshapes everything from family life and education to politics and public debate, in a country where the relationship between faith and the state has always been fiercely contested. The split between belief and non-belief today is best seen in a simple side-by-side comparison.

Yet a majority of non-believers does not mean a country empty of religion. France remains shaped by its Catholic heritage in its calendar, architecture, art and culture, and committed minorities of practising Catholics, Muslims, Protestants and others continue to believe strongly. The reality of 2026 is therefore a paradox: a broadly secular society still living amid the visible traces of a religious past, and home to vibrant if smaller communities of faith. Understanding this balance, between a non-believing majority and a believing minority, is essential to making sense of contemporary France, and it sits at the heart of debates about Islam, the second-largest faith, explored in our countries with the largest Muslim population analysis.

Belief in God in France: The Key Numbers in Context

To place belief in God within the wider religious landscape, it helps to look at how the French describe their religion. Around half the population (50%) still identifies as Christian, while roughly 42% report no religion, 3% are Muslim, 3% follow another faith and 1% are Jewish. The fact that belief in God (around 40%) now sits below the share identifying as Christian (50%) is telling: many who call themselves Christian by culture or upbringing no longer actually believe in God. This gap between nominal affiliation and genuine belief is the essence of French secularisation, and it frames every figure in this report.

Taken together, the numbers describe a France in the late stages of a long secular transition. Belief in God has fallen from a two-thirds majority in 1947 to a minority of around 40% in 2026, non-believers now outnumber believers, and the youngest adults believe least of all. Faith endures, strong and genuine, within committed religious communities, but it has drained away from the mainstream of French society, leaving a country that is culturally Christian yet largely non-believing. For researchers, religious organisations and anyone trying to understand modern France, the message is unmistakable: the question "do you believe in God?" now receives a negative answer from most of the country, and the figures should be revisited as each new survey wave refines this historic trend.
