Brazil is the world’s most populous Catholic-majority country and hosts the largest evangelical Protestant community in Latin America. Drawing on data from the 2022 Brazilian Demographic Census (IBGE, published June 2025), this paper examines how overwhelming Christian predominance — comprising approximately 83.6% of the population — functions as a multidimensional structural barrier to the growth of Islam in Brazil. Five interlocking mechanisms are identified and analyzed: colonial heritage and the embedding of Christian identity in national culture; low immigration flows from Muslim-majority countries; low conversion rates compounded by strong evangelical competition; deep social and family structures organized around Christian sacramental life; and Brazil’s exceptional status within global Islamic growth trajectories. The paper situates Brazil as a regional anomaly in the context of global Islamic expansion and argues that the resilience of Brazilian Christian identity constitutes the primary explanatory variable for Islam’s persistent marginality in the country.
