FRED redistributes series from the US statistical agencies, the Federal Reserve system and a number of international sources in one consistent format. It is free, and most of its US-government series are in the public domain.
All US indicators on worldstat.us come through FRED, as do a few OECD-sourced series for Japan and India. The series identifiers, such as SAHMREALTIME or T10Y3M, are printed on each indicator page.
