An atlas of religion in Portugal is presented in Lisbon

The book An Atlas of Religion in Portugal was presented at the Catholic University of Portugal bookstore in Lisbon on October 28, 2026. Coordinated by Alfredo Teixeira and published by Universidade Católica Editora, the work uses 2021 census data to map the religious geography of the country.

The study reveals that 80.2% of the resident population identifies as Catholic. Protestants and Evangelicals represent 2.13%, followed by other Christians at 1.04%, Testemunhas de Jeová at 0.72%, and Orthodox Christians at 0.69%. Non-Christian religious traditions total 1.14% of residents.

The project was developed by the Centro de Investigação em Teologia e Estudos de Religião of the Universidade Católica Portuguesa with researchers from the Instituto de Sociologia of the Faculdade de Letras of the Universidade do Porto. The Fundação Francisco Manuel dos Santos helped create a website for interactive access to the data.

During the presentation, former Minister of Culture Pedro Adão e Silva described religious diversity as a sign of social richness that also brings challenges. He noted that increased plurality in Portugal can lead to social tensions compared to more homogeneous societies.
