Politics and news often influence economic performance. Here's what was happening at the time:

- The League of Nations' first assembly takes place in Paris.
- The British Parliament passes the Fourth Home Rule Act, dividing Ireland into two parts and leading to a yearlong Anglo-Irish war in the southern counties.
- The Catholic Church canonizes Joan of Arc, formally making her a saint.
- The 19th Amendment to the constitution is ratified, granting U.S. woman suffrage for the first time.

Raw data for these calculations comes from the government of Canada's annual Consumer Price Index (CPI), established in 1914 and computed by Statistics Canada (StatCan).
