Proportion of Catholics in Spain 2011-2020

Although traditionally a Catholic country, Spain saw a decline in the number of believers over the past years. Compared to 2011, when the share of believers accounted for slightly over 70 percent of the Spanish population, the Catholic community lost approximately ten percent of their faithful by 2020 with a share of 61 percent of the surveyed population. Believers of a religion other than Catholicism accounted for approximately three percent of the Spanish population in 2019 according to the most recent data.

A Catholic majority, a practicing minority

Going to mass is no longer a thing in Spain, or so it would seem when looking at the latest statistics about the matter: over 60 percent of those who consider themselves Catholics almost never attend any religious service. The figures only increased in the past years, with 55.5 percent of the population never going to religious services in 2011 up to 62.1 percent in 2019. The share of population that stated to be practicing believers and go to mass every Sunday and on the most important holidays accounted for only 13.4 percent in 2019.

The not so Catholic Spain

Almost 27 percent of the surveyed population stated to be either non-believers or full atheists in 2019. Non-believers or people that do not have a religious faith maintained steadily over 14 percent over the past years with the latest figures showing a 16 percent of people that categorize themselves as so. The share of Spanish atheists is on the rise according to the most recent surveys, taking up 10.7 percent of respondents in 2019
