Different, obviously, as the religious demographics of overwhelmingly Catholic Poland are very different to the U.K's.
Recent Polish immigration to the U.K has resulted in a fairly large uptick in attendences at Catholic churches IIRC.
That's true- it's noticable where I live- so much so that they wish to recruit Polish priests. (They have to recruit priests anyway because they are suffering a severe shortage. I could point to statistics showing the downturn linked to the liberalisation of societal attitudes towards homosexuality...but I won't be controversial
) The number of Poles in Scotland is betwee 70-100,000 probably closer to the 100,000 mark which makes them the largest 'ethnic minority' in Scotland.
