Bits of Mesa that are now extremely low density suburban development were at one point large Hohokam pueblos. It's not an entirely fair comparison because it's essentially comparing high density midrise apartments to some of the least dense suburban sprawl in the US, but it's not wrong.
At a more regional level, the area around Cortez, CO is less densely populated than it was simply because virtually no one lives there now. Kayenta, much of the Navajo nation, the upper Gila region, etc are similar.
