There are 437 cities of 1 million or more population. There are roughly 5,000 cities of over 100,000 population. And there are 3,047,000 named communities in the world.
Seems to me that the number of routes in the global routing table should logically be closer to 5,000 than to 3,000,000.
If there is an exchange point per city over 100,000 (the route goes to the IXP and then to the actual provider)... Otherwise, there is a flaw in your calculation.
