Challenge: Graphing obesity trends
Here we have a case of worthwhile data and an interesting story about obesity trends. People are getting heavier younger. The graph was made to show this; however, it's hard to understand and kind of makes things more confusing. Can you redesign the above, using the same data, to tell the story more clearly?
This is what we know about the data. It comes from a study that took place between 1971 and 2006. We have obesity rates, separated by when study participants were born. So for example, in the above graph, the orange line shows the obesity trend for people who were born between 1956 and 1965. When that group was in between 30 and 39 years old, about 27% of them were obese.
It's a little confusing at first, but let it simmer for a little. It's actually not too bad.
Okay, now the question: are people getting fatter faster? The original graph suggests that yes, people are, but the story isn't as clear as it could be. Plus, it took 19 powerpoint slides to tell it. Your job is to put it all in one graphic. Are you up for it? I think so. Leave your suggestions and links to remakes in the comments below.
