Consumption of Diet Drinks in the United States

From the National Centers for Health Statistics:

About 20% of the U.S. population aged 2 years and over consumed diet drinks
on a given day during 2009‒2010. The percentage consuming diet drinks
was similar for females and males at all ages except among adolescents aged
12‒19. The percentage consuming diet drinks increased with age for both
males and females.

It's soda. No, it's pop.

I was at a wedding recently and the discussion evolved to what one calls carbonated beverages. It turns out that there is a website called Pop Vs Soda that addresses this very important issue. There is even a county-by-county map delineating the data. Western New York is pop territory while the rest of the state is soda country.
