Americans over the age of 65 are over three times more likely to prefer drinking coffee to drinking tea. Coffee's dominance, however, has been slipping ever since. Millennials are now just as likely to prefer tea as they are to prefer coffee.

This is very surprising to me. Among my friends almost everybody drinks coffee on a regular basis. Tea is not nearly as popular in my experience.

Might be more of the hipster mid-20s crowd drinking tea.
