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

- Margaret Thatcher becomes leader of the British Conservative Party, after defeating Edward Heath.
- Ethiopia abrogates its 3,000-year-old monarchy.
- Bill Gates and Paul Allen found Microsoft.
- The US signals the beginning of the end of its involvement Vietnam, after it begins to evacuate its citizens from Saigon.
- Gough Whitlam is removed by Governor General Sir John Kerr: the first time an elected Prime Minister had been deposed in 200 years (Australia).

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.
