density of hot babes is clearly higher in Poznan and lower in Katowice and Wroclaw.
There are 113 women for every 100 men in Wroclaw. Also, 1/7th of the city is made up of students. Result: Many hot babes. By your calculations 'southern' that would be: 10,000+ hot..................
But in fact , as 'freebird' mentions, it is all according to taste, and I have seen many beautiful people in and from many different countries.
