FRED has multiple layers of checks to ensure the accurate publication of data from trusted sources. When data releases are added or updated, FRED validates the data against data already published by the same source. The Data Desk looks for comparable structure and scope of the data and investigates deviations from past date releases. Each FRED graph also includes links back to the source materials, making it easy for FRED users to verify the accuracy of the data themselves and understand the methodology for a specific series.
