Statistics on Polish Catholicism in the Communist Era
The information presented in this table highlights some of the ambiguities regarding the position of the Roman Catholic Church in the Polish People's Republic. The basic message in these data is that Catholicism thrived between WWII and the 1990s. These decades saw an expanding network of parishes and a dramatic surge in the construction of church buildings. However, by comparing the last column of this chart with the overall increase in parishes (and with the information we gain from the other sources provided in the Teaching Module on the Roman Catholic Church in Poland), we see that it is more likely that the Church was indeed successfully improving its pastoral services.
This source is a part of the The Catholic Church in Poland, 1950-2000 teaching module.
