Today’s piece comes from the New York Times. It fits within a broader article about smoking in the United States. The map is a choropleth that compares the smoking rate across counties and states in 1996 and 2012. However, as the article talks about how difficult it has been to decrease the smoking rates among the poor, I wonder if even just a third map would be useful. This map could have shown the actual decline, perhaps in percentage points, of counties between 1996 and 2012. Or another related graphic could have tried to correlate income and said change.
