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 information in this dataset is manually input from Consumer Prices and Expenditure Patterns in Australia 1850–1914 for 1850-1900 and Australian Bureau of Statistics (2019) 6461.0 - Consumer Price Index: Concepts, Sources and Methods, 2019 §3.11 for later years.
