This sub-template returns the associated country's CPI for a specific year. It's used by {{Inflation/doc}} 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 sources for this dataset are Consumer price indices, nominal / real wages and welfare ratios of building craftsmen and labourers, 1260-1913 from 1409 to 1913, and Inflation 1800-2000, for 1914 to 2007.
