Very true. But the US is on the wrong end of that spectrum,
or in the middle. The US is far less densely populated than any of the other industrialized countries save Canada and the Confederation of Independent States otherwise known as the former Soviet Union. The US is roughly as densely populated as the Faroe Islands which is the most northerly inhabited space on the planet (those crazy Danes) equivalent to the top of Greenland.
The United States is less densely populated than Afghanistan. Now odds are all the empty space in Alaska accounts for that, but it's still true. The Ukraine, the breadbasket of the former Soviet Union is twice as densely populated as the US.
