As another way of looking at the question of who is engaged in thinking about mecfs, I accessed a public petition from the US with 3000+ signatories. And I did some analysis of the surnames.
All the techniques I used were fairly fraught so possibly the simplest trick is just ranking the surnames by frequency. You can see that list below. What this doesn't give you is detailed ethnic origin. Not in any way. What I see though is that this list of names is very similar to the most common names in the USA,
if you exclude hispanic names. ref:
https://en.wikipedia.org/wiki/Lists_of_most_common_surnames_in_North_American_countries)
Which perhaps raises a possibillity: if rates of english/scottish heritage and rates of hispanic heritage were inversely correlated, what we could be capturing is low rates of me/cfs among people with hispanic origin. Which would still be an epidemiological insight if there was something to it.
I note that the US census table
@forestglip has been using does not include Mexico or any south American countries as places people may say their ancestors came from. It does include "other groups" though, which has a negative coefficient and a low p-value.
