In an interview on the Freakonomics website, Hal Varian recommends that young people consider careers in data analysis. So who the heck is Hal Varian? He's Google's Chief Economist and I couldn't agree more. His answer:
"If you are looking for a career where your services will be in high demand, you should find something where you provide a scarce, complementary service to something that is getting ubiquitous and cheap. So what’s getting ubiquitous and cheap? Data. And what is complementary to data? Analysis. So my recommendation is to take lots of courses about how to manipulate and analyze data: databases, machine learning, econometrics, statistics, visualization, and so on."
