Economagic
Subscribed to by Calvin's Economics and Business Department, this site "is meant to be a comprehensive site of free, easily available economic time series data useful for economic research, in particular economic forecasting." Contains more than "200,000 time series for which data and custom charts can be retrieved. Though the greatest utility of this site is the vast number of economic time series, and the easily modified charts of that same data, an overlooked facility of great utility is the availability of Excel files for all series," which comes with the Level 1 subscription maintained by Econ and Bus, and accessible to our campus users.
"The majority of the data is USA data. The core data sets involve US macroeconomic data (that is, for the whole US), but the bulk of the data is employment data by local area -- state, county, MSA, and many cities and towns."
