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 Nominal Wage, Cost of Living, Real Wage and Land Rent Data for Korea 1906-1939 for 1906 to 1911, and Consumer Prices and Real Wages in Taiwan and Korea under Japanese Rule for 1912 to 1939.
