The fastest-growing religion in 2024 is Islam.
According to the Pew Research Center, Islam is projected to be the fastest-growing major religion in the world over the next few decades. This growth is driven by a combination of factors, including higher birth rates among Muslims, as well as conversions to Islam.
While Christianity remains the largest religion globally, its growth rate is expected to be slower than that of Islam. This is due to factors such as declining birth rates in some Christian-majority countries and a higher rate of people leaving Christianity than joining it.
It is important to note that these projections are based on current trends and may be subject to change. However, based on current data, Islam is projected to be the fastest-growing major religion in the world in 2024 and beyond.
