I'm no economist, but according to this super accurate spreadsheet I made - looks like China will overtake the US 2019. I make some bad calculations based on bad assumptions. Like GDP = GDP per cap * pop (though it worked out roughly). I took the average yearly growth of US from 2000 - 2016 and the average yearly growth of China from 2000 - 2016, plotted them and compared them. There is an intersect (China leading) on total GDP in 2019 and an intersect (China leading) of GDP per capita in 2030. Anyway, here's an image of it: https://imgur.com/vKjJCpN https://imgur.com/vKjJCpN
