At the big data conference in San Jose earlier this year, there was a speaker from the US Census. They deal with LOTS of data and do a fantastic job of making their datasets freely available with good documentation. A great example popped up recently from a PhD student at Harvard. He used the census job data to put a single dot on the map for every single job in America. You can see the full result here. This is such an exciting time in data analysis. We’re just scratching the surface of what kinds of decisions we can now make based on data instead of intuition.
