Regional studies on religiosity are non-existent in Spain and infrequent or non-existent in the Europe regional sphere, but not between countries. This article shows the regional variability in Spain of people who identify themselves as believers. It is argued that religious identification (believers) in Spain is regionally heterogeneous and that the regional effects associated with religiosity are altered by other ascriptive variables, gender, age, and educational attainment. 124 barometers have been merged, files from the Centro de Investigaciones Sociológicas (CIS) of Spain from January 2013 to May 2022, monthly, except Augusts, obtaining a sample size of 402,868 interviewees (394,906 identify themselves as religious or non-religious).
