Numerous studies suggest that polarization best describes the religious landscape of a growing number of Western countries. While a consensus is gradually emerging regarding the definition of religious polarization, no quantitative measure has been proposed to capture the concept. The present research note proposes two indices for the concept of religious polarization so that its degree can be compared across populations and its evolution can be traced over time. The proposed approach is applied to the US data of 2008–2016 and the Canadian data of 2008–2015. The relative ranking of the degree of polarization emerging from the computation of these indices accords with the previous literature, which has relied on the interpretation of distinct trends. These applications demonstrate the aptness of these indices for measuring religious polarization, as defined in the recent religious scholarship.
