Tell your story, respect your reader

Look at these two maps. They’re based on the same data: population gain or loss by county. But they tell vastly different stories.

In the first map, the graphic artist started with the two extreme values in the data set (-6.3% and +28.7%) and divided the color scale into 5 equal pieces. As a result, all of the counties losing population are lumped together with counties that had no change or that posted slight gains.

The map tells us that a lot of counties lost population or held steady, several counties added population, and exactly two (one in the top middle and one near the bottom middle) added a lot of population. Frankly, it’s not much of a story.

Now look at what the Washington Post‘s Christopher Ingraham did with the same data. Ingraham changed the color scheme: blue counties gained population and red counties lost. The color intensity changes for counties that gained or lost more than 1% or 2%.

Sea turtleThen he set out to replace the pyramid with a different model: a stack of turtles, each one riding on the back of the one below it. The stack, in Mark’s words, “is stories at the bottom, in the middle, and at the top. It is stories, like turtles, all the way down.”

That sounded good to me. Then I saw a story without any data. Continue reading
