Federal Reserve Economic Data is an online database consisting of hundred of thousands of economic data time series from scores of national, international, public, and private sources. FRED, created and maintained by the 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.
Allows you to retrieve vintage versions of economic data that were available on specific dates in history. In general, economic data for past observation periods are revised as more accurate estimates become available. As a result, previous vintages of data can be superseded and may no longer be available from various data sources. Vintage or real time economic data allows academics to reproduce others' research, build more accurate forecasting models, and analyze economic policy decisions using the data available at the time.
