The states are colored red or blue to indicate whether a majority of their voters voted for the Republican candidate, Mitt Romney, or the Democratic candidate, Barack Obama, respectively. Looking at this map it gives the impression that the Republican won the election handily, since there is rather more red on the map than there is blue. In fact, however, the reverse is true – it was the Democrats who won the election. The explanation for this apparent paradox, as pointed out by many people, is that the map fails to take account of the population distribution. It fails to allow for the fact that the population of the red states is on average significantly lower than that of the blue ones. The blue may be small in area, but they represent a large number of voters, which is what matters in an election.

We can correct for this by making use of a cartogram, a map in which the sizes of states are rescaled according to their population. That is, states are drawn with size proportional not to their acreage but to the number of their inhabitants, states with more people appearing larger than states with fewer, regardless of their actual area on the ground. On such a map, for example, the state of Rhode Island, with its 1.1 million inhabitants, would appear about twice the size of Wyoming, which has half a million, even though Wyoming has 60 times the acreage of Rhode Island.

  2. Can you create a map that shows which presidential candidate won each congressional district nation wide? This is interesting because if each state allowed electoral votes to to be split like Maine and Nebraska the total tally of electoral votes may differ. Additionally states such as Texas that are predominantly red everywhere except for south Texas would have the opportunity to cast some blue votes as well. States like Florida that are nearly split would be able to split their electoral votes according to the winner in each congressional district.

    Dems win concentrated areas in cities, but Repubs win much larger geos covering many more districts.

  4. Independent and Elizabeth Downeyu – I’ll see if I can find one or create one for 2012. In 2008, Obama won significantly more congressional districts than McCain (http://www.swingstateproject.com/diary/4161/).

    Please keep in mind that congressional districts are allocated by population, not geographic size, so a map may not easily capture the number of congressional districts in a dense city. For example, New York City has more congressional districts than Wyoming, Montana, Idaho, Alaska, North Dakota and South Dakota combined.

  5. Wondering why Alaska is not represented in these maps? You include Hawaii but not Alaska. Any idea why?
