james_davis_nicoll | A meaningless and fundamentally broken table

Everyone knows that the fraction of American Presidents who were Catholics is nothing as high as the number of Americans who are Catholics. Ever wonder which religions are over-represented amongst American Presidents?

Assuming this table can be taken at face value:

Religious affiliation of US Presidents in order of the degree to which their religion is over-represented amongst US Presidents if they had all been elected today and not in some past era when demographics were different:

[Fixed to correct Eisenhower's affiliation, to correct some math errors and to take into account reader comments]

Oddly, all but one of these denominations is batting out of its league. I suppose that is a reflection of religious diveristy and the uneven distribution between sects of interest in and possibility of achieving higher office.

I expected more Quakers.

I have not verified the numbers I am using and since I spotted one error in the original there may well be others.
