Subway Maps and Visualising Social Equality by James Chesire.
From the post:
Most government statistics are mapped according to official geographical units. Whilst such units are essential for data analysis and making decisions about, for example, government spending, they are hard for many people to relate to and they don’t particularly stand out on a map. This is why I tried a new method back in July 2012 to show life expectancy statistics in a fresh light by mapping them on to London Tube stations. The resulting ”Lives on the Line” map has been really popular with many people surprised at the extent of the variations in the data across London and also grateful for the way that it makes seemingly abstract statistics more easily accessible. To find out how I did it (and read some of the feedback) you can see here.
James gives a number of examples of the use of transportation lines making “abstract statistics more easily accessible.”
Worth a close look if you are interested in making dry municipal statistics part of the basis for social change.
