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

- The occupying powers grant full Sovereignty to West Germany.
- The Mainau Declaration against nuclear weapons is signed by 18 Nobel laureates.
- Rosa Parks is arrested in Montgomery, Alabama for refusing to give her seat to a white person and move to the back of the bus.

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.
