Field notes
The page explains that city boundaries follow continuous built-up areas rather than municipal borders, which changes how some familiar urban regions are grouped. It specifically notes that Tokyo includes Yokohama and Saitama, while Guangzhou includes Shenzhen, Foshan, and Dongguan. The site also says it rounds source populations, interpolates years between five-year data points, and redraws locations using the Equal Earth projection.
