And I thought New York was crowded...

Came across this photo of the population density of the world. More evidence why India and China are worth taking seriously.

Reminds me of a couple things:

First a bad joke: If you're a one in a million kind of guy in China or India, then there are a thousand people just like you.

Second an article that Malcolm Gladwell wrote about dependency ratios. Talks about how the success of countries, companies, and groups depends on the number of people producing vs. the number of people depending on those producers. In short, if you have a bunch of workers and no kids/retirees, then you don't get bogged down by overhead issues (time, cost, etc.) that will hold you back. Check it out...
