Not if your real research question is "what affects population density?",
which I suspect is what you really want to ask. If so, using -mlogit- with
cities as the dependent variable strikes me as a bizarre approach: asking
the question "does density affect the probability of a city being a city
(or being the city that it actually is)" makes little sense, to me at
least. In my opinion, the OLS formulation you provided is much more
sensible, so try that and work from there.
