Sage Data (formerly Data Planet) This link opens in a new windowData planet pulls in data from lots of different sources on lots of different subjects - health, education, government, banking, etc. It is useful because it gets data from different sources into one format, making it easy to merge and work with. For extra fun project ideas, check out the EASI Analytics Market Planner subject. Have you ever wondering exactly which fast food places are the most visited in your zip code? Preferred brand of whisky? How often they attend horse races? Lots of crazy stuff in there! The data coverage varies by subject (both in time and space). Some variables go all the way down to the census tract level, others are just available for the country or state as a whole. Some variables go back in time a few decades, others just the last few years.
