From StrangeMaps :
The US is one of the world’s biggest countries, with one of the world’s most numerous populations [1]. The 23rd Census of the United States, now under way, will provide us with updated information on the current size of America’s population, but until then, let’s assume – as this map does – that the country is inhabited by about 300 million people. With a total area of 3,794,101 sqare miles, that gives the US a population density of approximately 79 Americans per square mile.

Now, what if the whole population of the US would live in such a cheek-by-jowlish manner? How much space would they need? Texas? Nope. California? Think again. Pennsylvania? Nu-uh. Florida? Nice try. New Hampshire. That’s how much, or rather: how little space would be needed. The state would be ruined, though (imagine a Brooklyn-like sprawl of that size), but the rest of the country would be green and pleasantly devoid of people! As the legend to these maps point out, a further advantage would be that all Americans would be neighbors. Somehow, that does not sound like a very good idea.
