Here I wanna to have a comparision between Iran and Germany population distribution.

Accourding to Wikipedia the populaton of Iran is about 70 milion and Germany is 82 milion.
About 18 milion live in 5 largest cities of iran and about 7.7 live in 5 largest cities of Germany.

So, aproximately I could say 25% percent of Iranian live in 5 largest cities and for
Germany it is about 9% percent.

The numbers are not exactly( just trust me), but another interesting statistic is that
37 million or 45 percent Germany's people live in the 300 largest cities.
