You are using numbers that are 6 years out of date for a country that has had 6% YoY growth.

  The Chinese numbers are from 2019. The American numbers are from 2015. If anything the comparison strongly disadvantages the US, since there was robust growth in the latter half of the decade.

    Can you use a single source that contains the numbers for both China and the US, please? For such data points that have a lot of very different possible methodologies it's quite important to use the same source or ensure that the methodology is exactly the same.

      I think that is an unreasonable request for rigor for a casual internet forum comment. That amount of rigor you have to pay for, and at this point I think it's reasonable for you to do your own research and present such normalized numbers.

        It really isn't much to ask for. If you're making arguments based on really really shaky data you should not be making them at all. Comparing OECD regions to Chinese administrative metro areas is really quite absurd. The variance in Montréal for example depending on what you call a city can be almost 2x. For example, if you take the Tokyo Metro Area, you find a GDP per capita of 48k, with a PPP ratio of 0.98 we get 48k USD PPP. Comparing it to the Beijing Metro Area you have a 39k USD PPP. This took around 4 minutes to do for the two cities, so I really don't think it's a quantity of rigor you should pay for, nor an unreasonable amount of scrutiny for an internet comment at all. I was just trying to get the commenter to realize the issue with using two completely different data series in a comparison. You can also compare for example Jiangsu and South Kanto to find similar numbers.

Can you demonstrate your principles with your other comment [0], by using “a single source that contains the numbers” of many of the countries and claims you mentioned in that comment?

        I asked for either a single source or many sources with an identical methodology.

        Funny how you asked others to “use a single source that contains the numbers”, and yet you make arguments without providing any sources, as you did in your other comment I linked above. How do we know your arguments aren’t “based on really really shaky data”?
        sudosysgen 6y ago
        No one provided sources here. A partial source was provided by the other commenter. But if you ask, the source for inflation control is OECD inflation data, the source for Tokyo GTA GDP per capita is Wikipedia/SCMP, and the source for Beijing administrative region GDP is official national numbers.

        If it really isn't much to ask for, then it should be no problem for you to provide it no?
