John. Why should I take a weird foreigner seriously for that matter?

Keith. Per capita is how you state it, correct. Per capita when applied must have a weighting to make it relevant to the index. Try Orwell's assertion that some pigs are more equal than others for starters. Then look at how Israel' version of ONS do it for just about every situation.

Not that reality ever stopped your staunch assertion that if you read it somewhere everyone else is wrong....
