The data is from the London School of Economics Urban Age system. The map is a little bit hard to examine. Figures are sized by metropolis progress, building reduced progress metropolitan areas like London hard to examine. Due to the fact the dots are by now sized by number they could have kept the figures all at a readable size. Also employing a unique coloration for every continent is somewhat pointless. Even so the data is attention-grabbing-Lagos gains 85 new citizens just about every hour although Rio only gains ten.
The map under displays previous and projected progress by time period.
Green metropolitan areas noticed most of their progress occur by 1950 although the much more yellow kinds are at present seeing the most progress. Some metropolitan areas, especially in India have a much more combined pattern of concentric circles exhibiting continual progress all over previous and upcoming decades. These maps are a little bit hard to examine at this size. If you simply click on them, you can see greater measurements. Right here is a depth from the map above exhibiting Europe vs South Asia and East Africa.
