This sub-template returns the associated country's CPI for a specific year. It's used by {{Inflation/GR}} for calculating the inflation rate between two given years, which in turn is used by {{Inflation}} to calculate inflated values. It usually isn't meant to be called directly. The source for this dataset is Inflation 1800-2000. From 1833-1913 the source is South-Eastern European Monetary and Economic Statistics from the Nineteenth Century to World War II.
{{Inflation/GR/dataset|year}}
Providing no parameter or providing an invalid parameter will result in the "default" CPI, what usually means the latest one.
