I am trying to describe how cities and have been affected by the growing population in terms of the density of bodies.

This is how I have it at the moment but I am unsure whether it should be "more dense", or "denser"

"With the global human population increasing and areas becoming more dense"...

or

"With the global human population increasing and areas becoming denser"...

Which would be correct?
