Two religions have more than two billion adherents apiece, and the world's population has surpassed eight billion.  Christianity is the second most popular religion, after Islam.
 
Some unexpected revelations regarding religious trends, with a particular emphasis on islam and christianity, were made public by a recent Pew Research Center report. The survey states that approximately 64% of Americans identified as Christians in 2020. But by 2070, this percentage may fall to 46%, indicating that Christians will no longer make up the majority in the US. Thirty percent of Americans were not Christians in 2020, and six percent practiced another religion.
 
Changing religious trends
Generally speaking, Christians are older than members of other religions. Over seventy-five percent of young individuals in their early 60s identify as Christians, compared to about half of those in their early 20s. Among older generations, the percentage is significantly greater. Since there will be more Christian deaths than births, the total number of Christians will inevitably decline as older Christians die and younger, nonreligious people raise their children without religion.
 
Due primarily to continued immigration trends, other religions are predicted to increase and may account for 12% of the US population by 2070. According to the survey, 34% of those who were raised as Christians will abandon their faith by the time they are 30 years old.  Three percent of them will change their religion, and thirty-one percent will not identify with any religion at all. Conversely, 21% of those who were raised in a nonreligious household will become Christians. Because of this continuous change, Christianity's percentage in the US will continue to drop by 2050 and will drop below 50% by 2060.
 
US Religious Composition in 2070
The percentage of Americans who identify as Christian is predicted to fall to 46% by 2070, making them the most prevalent religious group but no longer the majority. The percentage of non-Christians will rise to 41%, while the percentage of people in other religious organizations will be 13%. These projections are predicated on existing patterns in mortality, migration, birth rates, and religious switching.
