Is Christianity Growing In The World

Christianity is a major force in the world today, with billions of followers around the world. It’s one of the oldest religions in the world and continues to be a dominant cultural force today, particularly in the western world. But is Christianity really growing in the world, or is it becoming less popular in some regions? To answer this question, let’s take a look at the latest data and insights on the topic.

According to recent estimates from the Pew Research Center, Christianity remains the world’s largest religion, with an estimated 2.4 billion people as of 2020. This number is up slightly from 2.37 billion in 2015, which shows a slight growth in Christian adherents worldwide. However, this growth is mostly due to population growth, particularly in the African continent and some parts of Asia.

When it comes to Christian growth in different countries, the picture is a bit more mixed. In the US, Christianity is still very popular, with an estimated 75% of Americans identifying as Christians. This represents a decline from 85% in 2007, according to a survey by the Public Religion Research Institute. This decline can largely be attributed to the rise of non-religious people in the country and a decrease in young people who are part of Christian denominations.

In many parts of Europe, Christianity is declining. According to a recent Gallup survey, only 38% of Europeans now identify as Christians, down from 60% in 2008. This can largely be attributed to an increase in immigration and the rise of non-Christian religions in the continent. In some countries, such as Germany, the decline has been even more substantial, with only 27% of citizens now identifying as Christians.

In many other parts of the world, however, Christianity is actually on the rise. In countries such as Nigeria and South Korea, the Christian population has grown significantly in recent decades. In sub-Saharan Africa, Christianity is the dominant religion, with an estimated 63% of people identifying as Christians. Similarly, in Latin America, where historically Catholicism was the dominant religion, the Christian population now stands at around 90%.

So while the global picture is nuanced, there are some clear trends to be seen. Christianity is still growing in many parts of the world, particularly in Africa and Latin America, while in many parts of Europe and the United States, it is in decline. In terms of exact numbers, Christianity is still the world’s largest religion, with a slight uptick in adherents in recent years.

Age Group

When it comes to Christian growth among different age groups, the picture is once again more complicated. In the United States, there is a notable decline among young people. According to the Pew Research Center, only 30% of Americans aged 18–29 identify as Christian, compared to 45% of those aged 40-59 and 63% of those over 65. This decline is largely attributed to the rise of the non-religious, including an increase in those who identify as “spiritual but not religious”.

In many parts of Europe, there is also a decline in Christianity among young people, but it is not as dramatic as in the United States. According to a recent survey by the German Institute for Economics, only 27% of 15-24 year-olds identify as Christian in Germany, down from 50% in 2000. This decline is likely due to the fact that many young people in the country have been raised in non-religious households.

In contrast to the United States and parts of Europe, the Christian population is actually growing among young people in many parts of the world. In Africa, Latin America, and some parts of Asia, there is a noticeable increase in the number of young people who identify as Christians. This is likely due to the fact that a large portion of these young people were born and raised in Christian households, and have also been exposed to Christian missionary activity.

Social Media

Social media has also played a major role in the rise and spread of Christianity in recent years. Christianity can now be found in all corners of the digital world, from Twitter and Facebook to YouTube and more. Social media has made it easier for Christians to share their faith and connect with other believers around the world. It has also provided a platform for churches and faith-based organizations to reach out to new and current members.

Social media is also one of the most effective tools for evangelization in certain parts of the world. In many parts of Africa and Latin America, for example, the Christian population is growing largely due to online evangelism. In some countries, up to 50% of the Christian population is actively engaged in online evangelism through social media.

Overall, it is clear that social media has had a significant impact on the growth of Christianity in recent years. In many parts of the world, it has provided a platform for faith-based organizations to reach out to new members, while also providing an effective tool for evangelization.

Impact of Technology

Technology has also played an important role in the growth and spread of Christianity. Technology has enabled churches and faith-based organizations to reach larger audiences with their messages. For example, the rise of mobile phones and the internet has enabled churches to reach people in remote areas, who would otherwise not have been able to access traditional churches.

Technology has also revolutionized Christian education, allowing religious organizations to offer courses and classes online. This has enabled people to access religious teachings from anywhere in the world, regardless of their physical location. Technology has also made it easier for Christians to access religious texts, such as the Bible, which can now be downloaded to a mobile device or computer.

Finally, technology has also made it easier for Christians to connect with one another. Social media has enabled people to connect to each other in meaningful ways, while also providing a platform for prayer and other spiritual activities. Technology has made it easier for people to find and meet like-minded people, and share their faith with one another.


Christian education has also played an important role in the spread of Christianity in recent years. Education can play an important role in helping individuals understand and practice their faith more deeply. There is a growing emphasis on providing religious education for both children and adults, with Christian schools and universities providing courses in religious studies, theology, and more.

Educational programs also provide an opportunity for Christian leaders to reach out to new members of their faith. Many churches and faith-based organizations now offer classes and seminars for people of all ages, which can make it easier for them to become involved in church activities and practices. It can also help inspire faith and make religious teachings more accessible to people.

Finally, religious education can also serve to strengthen existing faith. By providing educational programs, churches and faith-based organizations can foster a deeper understanding and appreciation of their faith. This can help to reduce doubt and strengthen individuals’ faith in Christianity.


Finally, politics has also had a major impact on the growth of Christianity in recent years. In some countries, such as the United States, Christianity has become increasingly politicized, with many politicians and political organizations using it as a platform for their own agendas. This has had both positive and negative outcomes, depending on one’s perspective. On the one hand, it has enabled Christian groups and organizations to galvanize support for certain policies and causes, while on the other hand, it has also given rise to increased polarization and intolerance between different faith groups.

In many parts of the world, Christianity has also become more closely associated with certain political ideologies and movements. In Europe, for example, there are now several right-wing political parties which strongly identify with Christianity. Similarly, in the United States, some conservative Christian groups have become increasingly active in politics, advocating for the interests of conservative Christians.

Overall, it is clear that politics has played an important role in the growth of Christianity in recent years. Political organizations and parties have used the power of Christianity to gain support for various causes and ideologies. While this has also led to increased polarization and intolerance between different faith groups, it has also enabled Christian organizations to gain a greater influence in political debates.
