Is it true that high population density creates poverty?

 

If so, is this true and are there exceptions to this rule?

 

What's the logic behind it (if it is true)?

I don't think so. Namibia has one of the lowest population densities yet still has a relatively high degree of poverty.

Where there is a high population density because people have good reasons to live there, such as in Hong Kong or Singapore, the high population density itself creates wealth, since it greatly inflates real estate prices. But where there is high population density for purely contingent reasons such as high birth-rate or political and religious factors which hem people into a crowded area, such as in Bangladesh, the high concentration of people can create poverty, at least where the population still depends on agriculture, which needs inexpensive and extensive tracts of land to be economically efficient.
