How Many People Leave Christianity Every Year

Background Information

Christianity is the religion of over 2.2 billion people in the world, and it has been a major part of culture and society for over two thousand years. However, there is much debate about the number of people who leave Christianity every year and what that means for the future of the faith. There is much evidence to suggest that the numbers of people who are leaving Christianity and embracing other religions is increasing, and this deserves further exploration.


A study published by the Pew Research Center in 2016 found that the percentage of Christian’s who switched to different religions over the past 10 years had risen significantly. 46% of Christians who left the faith adopted a different spiritual approach, and 16% turned to atheist. In addition, the Gallup poll reported that in 2018, 14% of Americans identified themselves as non-religious, a 4% increase from the 10% in 2005.

Expert Perspectives

Experts have various perspectives regarding the number of people leaving Christianity every year. Some experts point to the rise of technology and access to information as a contributing factor. Barry Kosmin, director of the Institute for the Study of Secularism in Society and Culture at Trinity College in Connecticut, said that “The Internet has opened up a vast new resource for seekers looking for religious options” and “The upsurge of nominally unaffiliated religious seekers shows that the Internet is a pathway from religion to religion, not from religion to the non-religious.”
Other experts suggest that the number of people leaving Christianity could be attributed to poor preaching and teaching in churches. Dr. Joungbin Lim, a Professor at Duke Divinity School, observed that “many Christian communities have failed in providing an education and way of life that can help people answer the ultimate questions of meaning, purpose, and truth” and “Christianity as a movement is not appealing to growing numbers of people, its relevance and power seem to be diminishing.”

My Insights and Analysis

From the data and expert perspectives, it seems that there are various contributing factors to the number of people leaving Christianity. Many of these factors relate to the changing times, such as access to wider spiritual perspectives, an increased focus on technology, and ineffective preaching and teaching in churches. However, Christianity isn’t necessarily losing its relevance or power, as evidenced by the increasing number of people who are turning to different faiths. It is important to remember that being a Christian is a personal choice and one’s faith should not be determined by external forces.

Cultural Impact

The increasing number of people leaving Christianity could have a significant cultural impact. For many churches, the decline in numbers could lead to a decrease in income, which could lead to problems with staff, resources, or buildings. There is also the danger that many people will lose touch with their Christian roots, leading to a society in which faith is no longer as prominent or as widely accepted. On the other hand, increased access to different faiths could lead to a more diverse and tolerant society.

Social Impact

The increasing number of people leaving Christianity could also have a significant social impact. Many Christians form part of the social fabric in their local community, and their departure could create a rift within that fabric. Churches are also often a place in which people can form meaningful relationships, offering social support and a sense of belonging. The decline in numbers could mean that there are fewer people who can provide these functions for others. On the other hand, people may find a new sense of community through different faiths or spiritual practices.

Economic Impact

The increasing number of people leaving Christianity could also have a significant economic impact. Churches often rely on donations and tithes from their congregations for their financial operation, and a decline in numbers could lead to budget cuts or a lack of resources. This could lead to a decrease in the number of church services and functions, as well as reduced employment opportunities and salaries for staff. On the other hand, people leaving Christianity may turn to different faiths which could provide an economic boost to alternate places of worship.

Political Impact

The increasing number of people leaving Christianity could also have a significant political impact. Christianity has long been an important part of politics and many prominent politicians either share Christianity as their faith or have openly called on its principles in their political pursuits. A decline in numbers could lead to fewer people who support and promote Christian values in politics, and this could lead to a shift in policies. On the other hand, Christians leaving the faith may form strong alliances with different spiritual communities and promote new principles, creating a more balanced political environment.
