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

• New Zealand becomes the only nation to legislate against nuclear power, when their Labour government legislates against nuclear weapons and nuclear powered vessels.
• Margaret Thatcher becomes the first British PM in 160 years to win a third consecutive term in office.
• The Dow Jones stock index falls by 508.32 points, the event is later known as Black Monday.

### Data Source & Citation

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.
