Walmart Spreads Like a Virus

Posted to Economics  |  Nathan Yau

Watch Walmart quickly expand like a deadly virus from the movie Outbreak. It’s particularly interesting to see Walmart “infect” an entire small region with multiple new stores opening at the same time in one area. There looks to be somewhere around 30 stores opening per year (rough guess) across the country, so I wonder what the map looks like now. It’s probably all blue except in those deserted Midwest regions. I wonder what the world map looks like.

Random quote:

When I lived in Maine, there wasn’t much to do, so when we were bored on a Friday night, we’d go hang out at Walmart.

That’s kind of sad, but uh, if that’s your thing, well, no, still sad.

Think Like a Statistician – Without the Math

I call myself a statistician, because, well, I’m a statistics graduate student. However, the most important things I’ve learned are less formal, but have proven extremely useful when working/playing with data.
