Spend enough time reading headlines about Christianity in the West and it is easy to come away with one conclusion: young people are abandoning the faith.

There is truth behind that concern. Younger generations in Canada are less likely to report a religious affiliation than the generations that came before them. Christianity has also lost substantial numbers of people through religious switching in Canada and other Western countries. Those are real trends, and Christians should not pretend otherwise.

But after looking more closely at the research, the picture is not nearly as simple as the headlines make it sound.

Some young adults who were raised Christian have left Christianity. Others were never raised Christian in the first place. Some still identify as Christian but participate very little in church or other religious activities. At the same time, there are young Christians who remain deeply committed to their faith, and some recent research suggests that decades of religious decline may be slowing in certain places.

So before asking why young people are leaving Christianity, there is a more important question to answer first:

Are they actually leaving—and what does the evidence tell us about what is happening?

Younger Canadians Are Less Religiously Affiliated

The generational difference in Canada is real.

Statistics Canada examined decades of General Social Survey data and found that religious affiliation among Canadians aged 15 and older fell from approximately 90% in 1985 to 68% in 2019. Participation in group religious activities at least once a month fell from 43% to 23% over the same period. Statistics Canada

The differences become particularly interesting when Canadians are compared at similar ages.

Among people who were 20 to 30 years old, 82% of Canadians born between 1960 and 1969 reported a religious affiliation. Among Canadians born between 1990 and 1999, that figure was only 54%. Monthly participation in group religious activities also fell between those cohorts, from 24% to 14%. Statistics Canada

Looking at Canadians surveyed between 2017 and 2019 produces a similar pattern. Eighty-five percent of those born between 1940 and 1959 reported a religious affiliation, compared with 77% of those born between 1960 and 1979 and 61% of those born between 1980 and 1999. Monthly group religious participation was 27%, 23% and 18%, respectively. Statistics Canada

There is an important qualification here.

These Statistics Canada figures measure religion generally, not Christianity alone. Canada includes Christians, Muslims, Hindus, Sikhs, Jews, Buddhists and people belonging to other religions. We should not turn a statistic about declining religious affiliation into a statistic about Christianity specifically.

What the data can establish is that younger Canadian generations have a substantially different relationship with organized religion than older Canadian generations.

This Is More Than Young People Going Through a Phase

One comforting explanation might be that young people have always been less religious and eventually return as they marry, have children and grow older.

The Canadian evidence does not support relying on that explanation.

Statistics Canada examined different birth cohorts over time and found that religious behaviour tended to remain relatively stable within generations, although some changes occurred as people aged. The larger effect came from one generation replacing another.

Statistics Canada concluded that the replacement of older, more religious cohorts by younger, less religious cohorts appears to be the main driver of Canada's long-term decline in religiosity. Statistics Canada

That matters.

If the difference were primarily about age, we could expect today's 25-year-olds simply to become much more religious when they are 45.

Instead, the evidence suggests that generations can carry substantially different relationships with religion throughout their lives.

It also points toward childhood and adolescence as particularly important periods in the formation of religious identity.

But Not Every Young Person Without Religion “Left Christianity”

This distinction is essential.

When we say young people are “leaving Christianity,” it sounds as though every religiously unaffiliated 25-year-old was once a Christian who rejected the faith.

That is not true.

Some were raised Christian and later left. Others grew up without a religious identity in the first place.

Recent U.S. research illustrates this difference particularly well. Pew Research Center's 2023–24 Religious Landscape Study surveyed more than 36,000 American adults and found both phenomena occurring: younger adults were more likely than older adults to have been raised without a religion, while younger adults were also more likely to have left Christianity after being raised Christian. Pew Research Center

Those are two very different stories.

One is:

Christian childhood → religiously unaffiliated adulthood.

The other is:

religiously unaffiliated childhood → religiously unaffiliated adulthood.

Only the first represents somebody leaving Christianity.

This matters because Christianity can decline across generations even without every new generation actively rejecting a faith they once held. If fewer children are raised within Christianity to begin with, the Christian share of the next generation can decline before religious switching is even considered.

Religious Switching Is Still a Major Part of the Story

That does not mean people aren't leaving Christianity.

They are.

Pew Research Center conducted nationally representative surveys across 36 countries in 2024, including Canada, examining the religion adults were raised in and the religion they identify with today. For countries other than the United States, the research drew on surveys of more than 41,000 adults. Pew Research Center

Importantly, Pew's international definition does not count movement between Christian traditions as leaving Christianity. Someone raised Catholic who becomes Protestant, for example, remains within Christianity for this analysis. Pew Research Center

The results are sobering.

Canada was among the countries where Christianity experienced a net loss from religious switching equivalent to at least 20 percentage points of the country's total adult population. The same broad pattern appeared in countries including the United States, United Kingdom, France, Germany, Australia, Sweden and Spain. Pew Research Center

That does not mean that 20% of Canadian Christians recently abandoned Christianity. The statistic is calculated as a share of the total adult population and compares the number who report leaving Christianity with the number entering it.

But it does establish something important:

Canada's changing Christian population cannot be explained entirely by immigration, birth rates or people simply changing denominations.

A substantial number of people raised Christian no longer identify as Christian.

And in most of the countries Pew examined, people leaving Christianity usually did not convert to another religion. Most became religiously unaffiliated—atheist, agnostic or “nothing in particular.” Pew Research Center

That changes the nature of the question.

It is not simply a competition between Christianity and another religion.

Increasingly, Christianity is encountering people who question whether they need a religion at all.

Why Do People Say They Leave Religion?

This is where Christians should be particularly careful.

It is easy to begin with an explanation we already believe and then search for statistics that confirm it.

Social media is sometimes blamed. Political movements are blamed. Churches are blamed. Parents are blamed. Universities are blamed. Changing sexual ethics are blamed. Young people themselves are blamed.

Some of those factors may influence particular people. But if we want to understand those who leave Christianity, we should first listen to what people who have actually changed their religious identity say.

Pew conducted a follow-up survey in May 2025 of 8,937 U.S. adults. Among Americans who had left the religion in which they were raised, 46% said stopping belief in the religion's teachings was an extremely or very important reason.

Another 38% said religion was not important in their lives, and 38% said they gradually drifted away.

Thirty-four percent cited their former religion's teachings about social and political issues, while 32% cited scandals involving clergy or religious leaders. Pew Research Center

These figures are American. We should not present them as Canadian statistics.

They nevertheless provide valuable evidence about something national census numbers cannot tell us: how people who changed their religious identity describe their own decisions.

And the answers are not reducible to one cultural villain.

Some stopped believing.

Some drifted.

Some ceased to see religion as important.

Some became disillusioned with religious institutions or leaders.

Some disagreed with particular teachings.

Those are different problems, and they should not be collapsed into a single explanation.

Sometimes Faith Does Not End With a Rejection. It Fades Through Neglect.

One finding deserves particular attention.

Nearly four in ten Americans who left their childhood religion said they had gradually drifted away. Pew Research Center

There may never have been one dramatic moment when they declared Christianity false. There may have been no argument, no scandal and no single event responsible for their departure.

Faith simply became less important.

That is something Christians should take seriously.

There is a difference between inheriting a Christian label and developing a faith that becomes part of how someone understands life, suffering, morality, forgiveness, purpose and their relationship with God.

Statistics cannot tell us whether someone's faith is genuine. Christianity itself teaches that belonging to Christ is considerably deeper than selecting “Christian” on a survey.

But the research does show us that religious identity can disappear through indifference as well as rejection.

For Christian parents in particular, that should encourage something better than fear.

The goal cannot merely be getting our children to call themselves Christians.

They need to understand what they are being taught and see what that faith looks like when it is lived.

Childhood Experience Has a Powerful Association With Adult Religious Identity

Pew's 2025 research uncovered one of the strongest relationships in the entire study.

Among Americans raised in a religion who described their childhood experience with that religion as mostly positive, 84% still identified with their childhood religion as adults. Only 10% were religiously unaffiliated.

Among those who described their childhood religious experience as negative, only 24% remained in their childhood religion, while 69% were religiously unaffiliated as adults. Pew Research Center

We have to be extremely careful about interpreting that finding.

It does not prove that a positive childhood religious experience causes someone to remain religious. Adults who kept their religion may also remember their childhood experiences more positively. Many other family, cultural and personal factors could be involved.

But the association is too large to ignore.

For Christian parents, I don't think the appropriate response is to make Christianity artificially easy, entertaining or free from difficult teachings so our children will stay.

Nor is it to frighten them into remaining Christian.

There is a much more demanding question:

What kind of Christianity are our children experiencing through us?

Do they see us confess when we are wrong?

Do they see grace alongside conviction?

Do they hear us admit when we don't know an answer?

Do they see prayer only when life falls apart, or as part of ordinary life?

Do they see Scripture used primarily to correct other people, or do they see it correcting us too?

Research cannot prove that answering those questions well will guarantee that a child remains Christian. Human beings make their own choices, and Christianity itself does not teach that parents can manufacture faith in another person.

But we should not underestimate the difference between teaching Christianity and living it in front of the people who know us best.

What About People Who Stay?

This is where the research becomes more encouraging.

Pew did not only ask people why they left.

It also asked people who remained in their childhood religion why they stayed.

The most common answer was not social pressure.

It was not family tradition.

It was not even religious community.

Among adults who retained their childhood religion, 64% said believing the religion's teachings was an extremely or very important reason they remained. Sixty-one percent said their religion fulfilled their spiritual needs, while 56% said it gave their lives meaning.

Community was important to 44%. Familiarity and traditions were each cited by 39%. Pew Research Center

Among lifelong Protestants specifically, 70% cited belief in their religion's teachings as a major reason they remained Protestant. Pew Research Center

That finding should encourage Christians.

It would be easy to look at declining affiliation and conclude that Christianity needs to become more culturally fashionable to survive.

The research does not establish that.

Among people who remain religious, actually believing what their religion teaches remains enormously important.

Christianity cannot guarantee its future by becoming whatever the surrounding culture wants it to become.

The Christian task is more fundamental: know what we believe, understand why we believe it, live consistently with it, and be willing to answer difficult questions when they come.

The Youngest Generation May Complicate the Decline Story

There is another reason Christians should resist panic.

The newest American evidence does not show Christianity's decline simply accelerating forever.

Pew's 2023–24 Religious Landscape Study found that the long decline of Christianity in the United States has slowed and may have temporarily leveled off. Across Pew surveys conducted since 2020, the Christian share of U.S. adults has generally remained within a relatively narrow range rather than continuing the previous pace of decline. Pew Research Center

Pew also found that among the youngest adults it studied, the percentage who were raised Christian and remain Christian was approximately the same as the cohort immediately preceding them.

That is not evidence of a Christian revival.

It does not tell us what will happen next.

And U.S. evidence should not simply be transferred to Canada.

But it is enough to challenge the assumption that every younger generation must inevitably leave Christianity faster than the one before it.

Demographic trends can change.

What Is Happening Among Young Canadians Right Now?

Canadian evidence deserves its own treatment.

Statistics Canada's long-term data clearly establish that younger generations have historically been less religiously affiliated than older ones. But newer Canadian survey research contains some interesting signs that the story may be becoming more complicated.

Cardus, working with the Angus Reid Institute, surveyed 5,003 Canadian adults in March 2025. The online sample was weighted to represent the Canadian adult population by region, sex, age, household income and education. The research was jointly commissioned and paid for by Angus Reid Institute and Cardus. Cardus

Among Canadians aged 18–34, 59% said they definitely or probably believed that God or a higher power exists, compared with 63% across Canadians of all ages.

More surprisingly, 16% of Canadians aged 18–34 reported attending religious services at least weekly, compared with 10% among those aged 35–54 and 12% among Canadians 55 and older. Cardus

Looking across fourteen surveys conducted between 2017 and 2025, Cardus reported that weekly religious-service attendance among Canadians overall declined slightly from 15% to 12%, while attendance among adults aged 18–34 remained around 16%. Cardus

An earlier 2024 measure produced another interesting result. Among Canadians who identified as Christian, Cardus classified 39% of Christians aged 18–34 as “religiously committed,” compared with 20% of Christians aged 55 and older, using a composite measure of religious belief and practice. Cardus

Those findings should be treated as supplementary survey evidence, not as replacements for Statistics Canada's national data.

But they raise an interesting possibility.

There may be proportionately fewer young Christians than there once were, while a meaningful portion of the younger people who do continue to identify as Christian take their faith seriously.

That is very different from saying Christianity has disappeared among young Canadians.

Is There a Christian Revival Among Young People?

There have recently been claims of renewed Christian interest among young adults in several Western countries.

We should be cautious.

Cardus reviewed some of this evidence and concluded that there are signs of increased openness toward religion among younger people in places such as the United Kingdom and United States. But when examining Canada specifically, its researchers said measurable evidence has not yet caught up with anecdotal reports of renewed youth interest in Christianity. Cardus

That is where we should leave the claim.

There are interesting signals.

There are reasons to keep watching.

There is not yet sufficient evidence for Premium Works—or anyone else—to confidently announce a Canadian Christian revival.

We don't need to exaggerate encouraging news to make Christianity encouraging.

Christians Do Not Need to Be Afraid of the Numbers

The research does contain uncomfortable findings.

Younger Canadians are less religiously affiliated than earlier generations.

Christianity has lost substantial numbers of people through religious switching.

Some people raised Christian no longer believe what Christianity teaches. Others gradually drift away until religion has little place in their lives.

We should be willing to look directly at those realities.

But that isn't the whole story.

Many people remain Christian precisely because they believe what their faith teaches, find that it meets profound spiritual needs and find meaning through it. A portion of people raised without religion later adopt one. The youngest American adults are not currently showing evidence of an endlessly accelerating departure from Christianity. And among younger Canadians, there remains a measurable population actively attending religious services and engaging seriously with faith. Pew Research Center

None of that proves what Christianity will look like fifty years from now.

More importantly, Christianity's truth has never depended upon winning a demographic contest.

A Christian does not need frightening statistics to make the Gospel urgent, and we do not need encouraging statistics to make it true.

What these numbers can do is challenge us to examine ourselves.

If younger people are asking difficult questions, Christians should not be afraid of those questions.

If people say they stopped believing Christian teaching, we should be capable of explaining what Christianity actually teaches and why we believe it.

If people gradually drift away, churches and families should think seriously about whether Christianity is being lived as a relationship with Christ or merely inherited as a cultural label.

If people have been wounded by Christians, we should be willing to acknowledge wrongdoing without pretending that human failure disproves Christ.

And if our children are watching us—and they are—then perhaps one of the most important things we can give them is not the appearance of perfect Christian parents, but an honest example of repentance, forgiveness, prayer, conviction, grace and dependence upon Christ.

We cannot force another person to believe.

We cannot guarantee that our children will remain Christians.

We cannot control what the next census will say.

But we can be faithful with what has been entrusted to us.

The research does not give Christians a reason for complacency.

It also does not give us a reason for despair.

Sources & Methodology

This article distinguishes between religious affiliation, religious participation and Christian identity wherever the available research allows. These measurements are related but are not interchangeable. Canadian long-term trends are based primarily on Statistics Canada data. Pew Research Center provides international religious-switching research and U.S. evidence concerning people's stated reasons for leaving or remaining in a religion. Cardus/Angus Reid research is used as supplementary Canadian evidence concerning recent young-adult religious participation and attitudes.

American findings about people's reasons for leaving religion are identified as American evidence and should not be interpreted as Canadian prevalence estimates. Likewise, associations—such as the relationship between childhood religious experience and adult religious identity—should not automatically be interpreted as proof of causation.
