The day of Donald Trump's election victory - 9 November - was the UK's most miserable day in over six years, according to the makers of a mood-monitoring smartphone app.
The Mappiness app has been gauging the mood of the nation since 2010 and has built up a database of 3.5 million responses contributed by 65,000 users.
New analysis of that data shows that, at only 57.7% happy, Trump’s election victory was more thoroughly depressing than the gales, floods and power cuts of Storm Imogen (Monday 8 February 2016, 57.9% happy, rank #2).
It was also worse than news of the UK’s decision to leave the EU (Friday 24 June 2016, 59.2% happy, rank #4).
Conversely, the happiest day over the full period of the Mappiness study to date was Christmas Day 2010 (75.7% happy), followed by Christmas Day 2011 (74.2% happy).
Dr George Mackerron, lecturer in the School of Business, Management and Economics at the University of Sussex and co-creator of Mappiness, has published a blog today (Monday 16 January 2017) about the new analysis.
