I researched that we are far from being overpopulated....on the other note, India and China is denser than here in the US.
According to the latest estimates, NYC has a population of 8,274,527 and the the land size of 300 sq miles...which is about 27,581 persons per square mile. Seattle has a latest population estimate of 594,000 with a land size of 85 sq miles...which means 6,988 ppsm. It is crazy imagining how to cram that many people in one square miles. And, in addition...San Francisco has a population of 808,000 crammed in only 46 square miles of land...which means 17,565 ppsm. It's not even close to the density which NYC has. It's all the cheating with thousands of skyscrapers that drape the manhattan island. :P I wonder what is the most dense city in the world...hmmm.
