Introducing ALFRED®: ArchivaL Federal Reserve Economic Data

Notify Me When New Series and Features Are Added

Using ALFRED® you can retrieve vintage versions of 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 As a result, previous vintages of data can be superseded and may no longer be available from various data sources.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 data allows academics to reproduce others' research, build more accurate forecasting models, and analyze economic policy decisions using the data available at the time.

Currently, vintage data are available for 236588 series in 8 FRED categories:

The earliest vintage available is 1927-01-26. Over time, we plan to increase the number of series and vintages available.

Note that there are two ways to download vintage data — directly from the ALFRED® website or by using 'My Data Lists.'

How to Retrieve Vintage Data from the ALFRED® website

Vintage data may be downloaded directly from the ALFRED website. The advantage of this method is that a user account is not needed to retrieve data. For further information, please see the Download Data Help and the ALFRED Help pages on the ALFRED website.

How to Retrieve Vintage Data Using a Data List

Vintage data may be downloaded using 'My Data Lists'. The advantages of this method are that you can create data sets containing different series, and your data list is stored on a web server for future use.

Note that a user account is required to download vintage data using a data list. For a step-by-step tutorial on how to set up a data list, please see How to Use 'My Data Lists'.

Conclusion

Vintage data allows academics to reproduce others' research, build more accurate forecasting models, and analyze economic policy decisions using the data available at the time. In the future we plan to add more features to 'My Data Lists' and the ALFRED® website.
