Euan McColm in today's Scotland on Sunday article about the new Roman Catholic Archbishop of Edinburgh and St Andrews, who replaces his disgraced predecessor Keith O'Brien, casually refers to the 'not far off a million Scots who are Roman Catholics'.
In fact in the 2001 census there were 800,000 Roman Catholics in Scotland (16% of the population).
The 2011 Scottish Social Attitude Survey data put the figure at 12% or 600,000
And these figures are likely to have continued to fall in the last two years since then.
