A gender gap in the religiosity of men and women is one of the classical topic of sociology and psychology of religion. Until recently, however, most of the researcher were conducted in Western European and the USA, which calls into question the thesis about the universality of this phenomenon. Hitherto no systematic analysis of gender gap in the religiosity was conducted for Poland. The following text has one descriptive and one explanatory purpose. It seeks to provide answers to the following questions: (1) Does the GGR exist in Poland, and, if so, to which extent and in which dimension of religiosity? Which GGR is persistent, and which changes over time?; and (2) Do structural variables or ideology explain the observed GGR change in time and in which dimension of religiosity? Do we observe the same trend across all dimensions of religiosity?
