Data.gov

Artickle from the Hill Library:

Federal government agencies produce enormous amounts of data; some statistics and information sources are well-known, while others less so. Whether it’s a list of failed banks, BP oil recovery data, or a map of income and employment patterns back to the 1970s, it’s likely the available information is of interest to someone, somewhere.

An Open Government Initiative by the current administration, Data.gov’s purpose is to help the general public more easily find, download, and use datasets that are generated and held by the Federal Government.

The site provides descriptions of the available datasets, information about how to access them, and links to tools that leverage them. While still not completely comprehensive, datasets continue to be added all the time. Geodata have recently been added as well.
