What is FRED?
 Short for Federal Reserve Economic Data, FRED is an online database 
consisting of more than 72,000 economic data time series from 54 
national, international, public, and private sources. FRED, created and 
maintained by Research Department at the Federal Reserve Bank of St. 
Louis, goes far beyond simply providing data: It combines data with a 
powerful mix of tools that help the user understand, interact with, 
display, and disseminate the data. In essence, FRED helps users tell 
their data stories. The purpose of this article is to guide the 
potential (or current) FRED user through the various aspects and tools 
of the database.
As mentioned above, as of the time of this writing, FRED contains 
more than 55,000 data series from over 40 sources. These are not static 
figures. The Research Department has a firm commitment to the growth
 of the database. Since its inception, FRED has contained many of the 
more popular figures reported by the Board of Governors, Bureau of 
Economic Analysis, Bureau of Labor Statistics, and Census—among others. 
Through time, FRED has expanded its collection to include many more 
international, national, and regional data series. More recently, it has
 become clear that data surrounding other topics and geographies must 
also be included if FRED is to best serve its users. Naturally, care 
must be taken to add data in a thorough and prudent manner; 
nevertheless, the data content will continue to grow and evolve.
Certain data, as it travels through time, is subject to revision. 
Anyone who follows GDP long enough will be familiar with the BEA 
revising (up or down) their quarterly released figure. The FRED database
 always contains and displays the most recent revision—or vintage—of the
 data available. But FRED’s real-time relative, the aforementioned ALFRED
 (ArchivaL Federal Reserve Economic Database), captures all of these 
individual revisions to a data series. This means that collectively, 
FRED and ALFRED data can literally be used as a data time machine, 
allowing users access to the precise data that their predecessors used. 
Researchers often attempt to replicate results of previous academic 
papers or use data to “train” economic models; in these instances, the 
relevance of these FRED tools becomes clear.
