The San Francisco Bay Area has one of the largest Muslim populations in the United States: nearly 250,000 Muslims live in the six counties surrounding the city. This benchmark study, the first of its kind on the Bay Area’s Muslim community, provides groundbreaking data on its demographics, sense of identity, economic wellbeing, political and civic engagement, and the challenges that it faces. The resulting data is useful for academics and practitioners wishing to pursue further research, as well as for the community and its leaders, philanthropists and foundations, and policymakers. It will serve as an important tool for advocacy and media purposes, given that data about the community has often been misrepresented.
