5 Largest Cities by 30º Latitude/Longitude Blocks on the World Map Grid
The world map has been divided in a grid with lines every 30º in latitude and longitude! Can you identify the five largest cities in each block? Is it the first time that San Juan de Marcona appears on a world map?!
Data from citypopulation for 1M cities, geonames.org for smaller ones
Cities smaller than 10,000 are considered only if they are the largest within 100 km
In the list of top 5 cities you are now allowed to have 2 in the same country that are less than 50 km away from each other
The dots at the top/bottom borders of the map have been moved as they are too near the Poles to appear on the map
