English is often called the world language, and not without reason, yet outside the Anglosphere and parts of Europe, it’s only spoken by an elite. Which makes me wonder: what proportion of world GDP accrues to the minority of the world population that speaks good English?
The question immediately runs into an operationalisational quagmire. Or to put it in language that does not contain the abstract suffix ‘ation’ twice in one word: it’s practically impossible to determine how many people speak English, and there’s bound to be no data whatsoever linking the number of English speakers in each country to their slice of the national pie. However, this need not stop us making a rough and ready estimate. I’ve tried to do just that, and my provisional and highly questionable ballpark statistic would be that 10% of the world population accounts for half of global GDP.
But some linguistically-minded economist, or vice versa, may have come up with something slightly more reliable. Do any of you know of such an effort? I’d love to hear about it!
