Interesting analysis which comes to the wrong conclusion based on a flawed/meaningless data point.
"Population per course" MIGHT mean something(as if the everyday lives of inner city Londoners, and large cities in the industrial north has anything to do with access to mainly private golf clubs) but the stat that would mattter would be golf tourist population per course, in which case England blows Ireland/Scotland out of the water, especially if you're talking about the 5/15 courses they discuss which are inundated with tourists in Ireland and Scotland.
So England wins as logically we all know to be the right answer.
Value courses-somehow they found only 6 "good" courses in Ireland for under $150 US? Seriously?
Even at the new shockingly inflated green fee of Narin and Portnoo of 132 euros, using their exchange rate of 1.11 to $, it checks in under their "value" price for "good" courses of $150, yet doesn't make their Irish list?($150 not value IMHO but qualifies by their criteria)
Northwest golf club is more than "good"-must be too cheap at 30 euro
Strandill is certainly at least "good" yet nowhere to be found at 75 euro highest rate for an International visitor
Ballyliffin? two at least "good" courses at? Holy pandemic! just checked their 2020 rates 200 euros to play the Glashedy-just wow....
Donegal-while not value IMHO at $130 euro, it clocks in below their $150 US limit
Dunfanaghy-won't go there but...I prefer it to many and is certainly value at 25 or so euro
Cruit Island?
Sadly, all kind've irrelevant as those newly inflated prices are sure to crater very shortly, as they did post 2008
