The most recent U.S. Mosque Survey, conducted in 2020, found that the greater Detroit area had the fourth-highest number of mosques—104—of any large metro. Phoenix was not among the top 10.
The Mosque Survey counted 35 mosques in Arizona overall, a slight uptick from the 2010 survey but less than a third of the Michigan total. The number of mosques nationwide also climbed over the same period, an increase researchers attributed to the country’s growing Muslim population.
In 2018, Pew Research estimated that the number of people identifying as Muslim was increasing by about 100,000 annually, a trend expected to continue. Still, Pew surveys over the past decade show that Muslims consistently make up just 1% of the U.S. population.
