Great work 
, I'd also be very interested in seeing an Edinburgh catholic shade map. Particularly surprising to me in that map is Leith, which I'd have expected to be much more culturally catholic than other areas for obvious reasons.
Perhaps a reason for the high none in Liberton/Gilmerton and sighthill is the lack of anything to bind them to the church of Scotland in the way there is in Glasgow. Maybe Glasgow is more the anomaly here than Edinburgh?
What's unfortunate is that this information has only been released for the 2001 census. As such we've never really been able to follow trends. Catholic's account for over 70% in places like Barra, Vatersay, Eriskay etc which is the oldest concentration in the country. They are over 50% in places like Coatbridge Kirkshaws, Croy, Old Monkland and over 40% in Greenock, Blantyre, Uddingston, Chapelhall and parts of Dumbarton.
As for Edinburgh, any pattern that would have existed has dissapated. They make up 11% in leafy Meadowbank for example but only 12% in Leith Links. Their best showing in Edinburgh is Restalrig at 16.45%, so their isn't much of a stark divide. What may have happened of course is that their population was dispersed post-war. Looking at Glenrothes they form less than 10%. Looking at Livingston, they make up less than 15%; less than places like Blackburn and Fauldhouse. Perhaps they were never that strong to begin with?
So ignoring the southerly Outer Hebrides its basically a map of where the catholic irish settled, and its very interesting that these patterns have continued for 150 years, although it makes it all the more surprising that there doesn't seem to be a pattern in Edinburgh. Apparently Edinburgh was 6.5% Irish born in 1851, although they did congregate in specific areas like the cowgate ( Hibs were formed out of St Patrick's church in the area by a canon Hannan) and leith. Obviously Edinburgh was never like Glasgow, but it did still have a reasonably large number, perhaps the answer is done to post war resettlement, and gentrification in areas like the cowgate, although restalrig IIRC was where many leithers were resettled. Out of interest, what's the lowest catholic percentage?
