The chart above shows the population density of EU and US states.  Not surprisingly, the European Union is much more densely populated than the US is, but what is surprising is how much more densely populated the least densely populated state in the EU is than several US states.

The chart above shows the population density of US states.  Surprisingly, it is not a small state that is the most densely populated, however it does adjoin two major metropolises in New York and Philadelphia.

The chart above shows the population density of EU member states.  As Malta is such a small state, it is not surprising that its population density is so high, but what is surprising is how low Luxembourg's is.

The chart above shows the Purchasing Power Parity Gross Domestic Product (GDP PPP) of EU and US regions per square mile of territory in US dollars.  Only three regions produce over $10 million per square mile of territory: the Western EU, the Northeastern US, and the Southern EU; while only the Western EU and the Northeastern US make over $20 million.

The chart above shows the Purchasing Power Parity Gross Domestic Product (GDP PPP) of EU regions per square kilometer of territory in euros.  The Western EU has such a high GDP per area that it is more than double the remaining regions' combined GDP per area.

The chart above shows the Purchasing Power Parity Gross Domestic Product (GDP PPP) of US regions per square mile of territory in US dollars.  The Northeast has such a high GDP per area that it would be nearly twice as much as the three other regions combined.

The chart above shows the Purchasing Power Parity Gross Domestic Product (GDP PPP) of EU and US states per square mile of territory in US dollars.  EU and US states are distributed pretty much equally in this metric.

The chart above shows the Purchasing Power Parity Gross Domestic Product (GDP PPP) of US states per square mile of territory.  The Northeast does really well in this metric.

The chart above shows the Purchasing Power Parity Gross Domestic Product (GDP PPP) of EU states per square kilometer of territory.  Even though Western EU states have relatively large states, they still manage an impressive showing.

The chart above shows the area of each of the EU and US regions.  The Western US is so large that it can fit the entirety of the European Union within it.
