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

- Mohandas Gandhi protests British salt tax by a 200-mile-long walk.
- Clyde Tombaugh discovers Pluto.
- Lawrence Hyland discovers the first radar by accident.
- Roald Amundsen's leads the first expedition to reach the South Pole.

Raw data for these calculations comes from the composite price index published by the UK Office for National Statistics (ONS). A composite index is created by combining price data from several different published sources, both official and unofficial. The Consumer Price Index, normally used to compute inflation, has only been tracked since 1988. All inflation calculations after 1988 use the Office for National Statistics' Consumer Price Index, except for 2017, which is based on The Bank of England's forecast.
