The chart above shows the miles of rail per square mile of land in US states.  It's surprising to see that Western states have so little rail compared to the size of their area as rail has been romantically associated with the frontier lands.

The chart above shows the miles of roads per square mile of land in EU and US regions.  Only the Western EU has more than three miles of road for every square mile of territory.

The chart above shows the miles of roads per square mile of land in US regions.  Only the Northeast has more than two miles of road for every square mile of territory.  For comparison, a typical Manhattan square mile has approximately 25 miles of roadways.

The chart above shows the kilometers of roads per square kilometer of land in EU regions.  The Northern EU, with its vast expanses of land, is the least paved region per square kilometer.  It is also the only region that has less than half of a kilometer of road per every square kilometer of territory.

The chart above shows the miles of roads per square mile of land in EU and US states.  New Jersey, which has the dubious distinction of being a series of roads connecting New York to Pennsylvania, is the most paved state in the US but even it is no match for the Netherlands, Belgium, and Malta which are the most paved states in both the EU and the US.  Malta, which is essentially a city-state is the most paved having nearly three times as many roads relative to its territory as New Jersey has.

The chart above shows the kilometers of roads per square kilometer of land in EU states.  No surprise that small states that are very urban in nature have more roads per square kilometer of territory.

The chart above shows the miles of roads per square mile of land in US states.  For comparison, a typical urban square mile in Manhattan has approximately 25 miles of road for every square mile of area.  The most densely paved state, New Jersey, does not even come close.

The chart above shows the population density of EU and US regions.  The European Union is far more densely populated than the United States having the two most densely populated regions while the United States has three of the four least densely populated regions.

The chart above shows the population density of EU regions.  The Western EU is the most densely populated while the Northern EU is the most sparsely populated.

The chart above shows the population density of US regions.  The Northeast is clearly the most densely populated region and is so much so that it is over twice as densely populated as the next most densely populated region.
