Islam is often cited as the fastest-growing religion in Russia.
While Orthodox Christianity remains the largest religion in Russia, Islam is experiencing significant growth, primarily due to higher birth rates among Muslim populations and immigration. Some reports suggest that Muslims currently constitute a substantial percentage of the Russian population, with projections indicating further increases in the coming years. The exact figures vary depending on the source and methodology used. While difficult to pinpoint an exact percentage, estimates range significantly, demonstrating the ongoing demographic shifts occurring within the country's religious landscape.
