Pew Research Center Religion & Public Life
In recent years, Europe has experienced a record influx of asylum seekers fleeing conflicts in Syria and other predominantly Muslim countries. This wave of Muslim migrants has prompted debate about immigration and security policies in numerous countries and has raised questions about the current and future number of Muslims in Europe.
To see how the size of Europe’s Muslim population may change in the coming decades, Pew Research Center has modeled three scenarios that vary depending on future levels of migration.
Current (2016)
Even if all migration into Europe were to immediately and permanently stop – a “zero migration†scenario – the Muslim population of Europe still would be expected to rise from the current level of 4.9% to 7.4% by the year 2050. This is because Muslims are younger (by 13 years, on average) and have higher fertility (one child more per woman, on average) than other Europeans, mirroring a global pattern.
A second, “medium†migration scenario assumes that all refugee flows will stop as of mid-2016 but that recent levels of “regular†migration to Europe will continue (i.e., migration of those who come for reasons other than seeking asylum; see note on terms below). Under these conditions, Muslims could reach 11.2% of Europe’s population in 2050.
Finally, a “high†migration scenario projects the record flow of refugees into Europe between 2014 and 2016 to continue indefinitely into the future with the same religious composition (i.e., mostly made up of Muslims) in addition to the typical annual flow of regular migrants. In this scenario, Muslims could make up 14% of Europe’s population by 2050 – nearly triple the current share
