Reasoning:

• The most reliable demographic data, from the Pew Research Center, estimated approximately 44.1 million Muslims in Europe in 2010, and about 45.6 million as of 2020¹²³.
• A 2025 estimate from NextBigFuture places Europe's Muslim population at around 46 million, or roughly 6% of the continent's total population⁴.
• Pew projected that the Muslim population would exceed 58 million by 2030 under current trends, but that figure is a future projection, not the present reality¹³.
• The figure of 50 million is commonly cited as a rough estimate or projection, but it is higher than the most rigorous current estimates, which suggest approximately 45–46 million Muslims in Europe as of the mid-2020s²⁴.
• Less reliable sources such as MuslimPopulation.com claim over 62 million in 2024, but these estimates deviate significantly from the Pew baseline data and appear to overcount⁵.
• Therefore, the claim of 50 million is in the right ballpark but slightly inflated compared to the best available evidence, making it an approximate rather than precise statement.
