FRED is a comprehensive up-to-date data source maintained by the Federal Reserve Bank of St Louis in the US, which is part of the US central banking system. If you want real-time macroeconomic data on the German unemployment rate or China's output growth, you do not need to learn German and Chinese, or struggle to get to grips with national archives, because FRED does it for you! Fred contains the main macroeconomic statistics for almost all developed countries going back to the 19605. FRED also allows you to make your own graphs and export data into a spreadsheet. To learn how to use FRED to nd macroeconomic data, follow these steps: 0 Visit the FRED website.

FRED tells you that the real GDP is \"chained\" in a specic year, i.e. it is evaluated in terms of constant prices for that year. Note that the real GDP and the nominal GDP series cross at one point.
