How do I calculate the physiological density of Namibia? I can't find it!! HELP!! :)

Answer 1

I think if you use different wording, you'll find what you need. For example, instead of "human geography," I would say "demographics."

Take a look at some of these articles:

... especially the 2nd, 3rd, and 6th ones.
