The most densely mapped locations in OSM

(FSVO "mapped")

If you render the world on zoom level 16, there are 67 million "meta tiles" (each covering an area of 8x8 tiles). The majority of them are in the sea, obviously, and unlikely to have any data. 20 million meta tiles are not in the sea; of these, roughly a quarter have at least one node.

As of 22nd May 2013, only 208 of these meta tiles have more than 100,000 nodes on them; the front-runner has a whopping 433,000. (116 are in France, 47 in the US, 9 in Cameroon, 6 in Indonesia, 4 each in Japan, Uganda, and Italia, and a few in other countries.) Here is the list of those top 208 areas. (Germany, which has one of the most active mapping communities in OSM, has just one tile on this list.)

There's also a list with nodes per square kilometre which basically corrects the list below by the varying size of z16 tiles across the globe.
