Template:Inflation/doc/cpi-ch

This sub-template returns the associated country's CPI for a specific year. It's used by undefined 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 Deflating Swiss Prices over the Past Five Centuries for 1501 to 1813, and Federal Statistics Office, CPI, Global index on all index bases for 1814 to 2021.

Usage
Providing no parameter or providing an invalid parameter will result in the "default" CPI, what usually means the latest one.
