According to the investigation, which covered the four Russian-occupied regions of Ukraine that have been fully or partially under Russian control since 2022, but did not include Crimea, just 902 of the 1,967 religious congregations that existed before the war now remain.
While this is due in part to the depopulation of the four war-torn regions, the fact that not all faiths have been affected equally by the phenomenon suggests that there are other factors at play. Most affected are Orthodox Christian churches not subject to the authority of the Moscow Patriarchate, the highest body of the Russian Orthodox Church (ROC).
