(I have a "sortable spreadsheet with columns for Year of WHC, decision, SP etc which I could put up if you wish to play with the data to identify your own "patterns" and conclusions)
That would be great, Solivagant.
added Khor Dubai and Klondyke from 2018
Khor Dubai should be out, as it has been referred once, which means (at least in principle) that OUV has been recognised for the site.
a few SPs who have actually "cleared out" at least some "Rejects/Defers" etc from their old T Lists. UK. Ger, Nor, Lat and Lux
And even there some of these sites have been cleared for technical reasons (e.g. Cambridge) rather than acknowledged lack of OUV.
even if an "educated" one!
Some of these rely on official statements from the sites. Innsbruck or Francke Foundations for example have officially given up their WHS aspirations despite still being on the T-list.
UK. Ger, Nor, Lat and Lux account for all but 4 of them
Not quite - There are also sites from Afghanistan, Algeria, Argentina, China, Colombia, Costa Rica, Croatia, Cyprus, Czechia, Ethiopia, France, Greece, Indonesia, Italy, Jamaica, Kyrgyzstan, Lybia, Mexico, Mongolia, Nigeria, Pakistan, Philippines, Poland, Slovakia, Spain, Uruguay and USA.
I think the mistake lies in the total number - you cite 31 fitting sites whereas there are in fact 65 cultural FTWHS that have been deferred, rejected or withdrawn. This is the second list above. The total list (with your correct addition of Klondike) comprises of 155 sites - 90 are still on the T-list and 65 have been removed.
