You may or you may not have an argument - but you only present the most cliché, most superficial version. You merely divide total population by total area, which is utterly useless and misleading. Why does that keep happening on a supposedly "better" forum like HN? Each time this topic is touched this exact same tired and wrong pseudo-argument is presented as if population follows an equal distribution per area.

Just like in the rest of the world, in the US too the vast majority of people are clustered in and around urban areas. In order to achieve your goal/argument you counted vast stretches of nothingness. At least since the early 20th century migration to cities has been going on, and it still does - large urbanized areas continue to suck in people from the already emptier areas of the country.
