Who is a millennial? An example of handling uncertainty

I found this fascinating chart from CNBC, which attempts to nail down the definition of a millennial. It turns out everyone defines "millennials" differently. They found 23 different definitions. Some media outlets apply different definitions in different items. I appreciate this effort a lot. The design is thoughtful. In making this chart, the designer added...
