Public opinion on religion and religiosity

Although most Poles are Catholics, their religiosity is decreasing year by year. The COVID-19 pandemic has significantly affected the scale of participation in Sunday Mass and the sacramental life of Polish Catholics. The proportion of people attending Sunday Mass dropped to 28.3 percent in 2021. Due to the pandemic restrictions, the number of people receiving Holy Communion also decreased.
Most Poles agreed with the presence of crosses in public buildings in 2021. In contrast, only 15 percent of respondents favored priests instructing people on how to vote in elections. Almost every second respondent in Poland had a negative opinion about Muslims in 2019.
