Okay, this has nothing to do with Korean entertainment, but I found it wildly entertaining. GAPMINDER is a great website about world health and economics, with amazing tools for graphically displaying those statistics.
For example, here is a graph comparing North Korean and South Korean incomes-per-person and life expectancy from 1960 to the present.
It is a big database so it might take a couple of minutes to load, but it is pretty cool stuff. Once it is loaded, you can look at so many things:
- Comparing the percentage of people in Korea living in cities to income since 1960 here.
- South Korea's Internet users per 100 people since 1990 here
