The U.S. Census provides an overwhelming volume of surprisingly detailed data across the United States economy (among other sectors). I recently had the opportunity to work with some of the economic indicators, but found the data frequently inaccessible due to formatting and sheer volume (seriously, they make a TON of data available). Further discussion with several economically focused colleagues invited the creation of an interactive visualization on the Business Dynamic Statistics: Firm Statistics data set. These statistics present business creation and destruction on a state-by-state from 1977-2013.
