Uh.... there were 6000 soldiers of Gondor at Minas Tirith. And many were held back to fight Corsairs.

Gondor's population survived quite well. If you look at the population charts in the Atlas of Middle-earth for the Third Age, Gondor is quite densely populated in certain spots. Arnor's former territories are so scarecly populated, the population isnt even listed as "sparse".
