Look at the size the 10% bar is in the 40-49 graph. Then the 6% bars in the 50-59 graph. Then look at the size of the 9% bar in the 60-69 graph. And then the Other bar (8%) in the 70+ graph.
Then go backup and look at the LG and Other bars (8% total) in the top graph. Whoever made this graphic is either intentionally misleading or just plain dumb.
Edit: The 78%, 80%, an 85% bars are also all exactly the same size. It just gets worse the longer you look at it.
