We know that Cambridge is Britain’s best city for business and London is the best for tourism and entertainment, but which city is Britain’s smartest?

Now, while ‘smartest’ is quite difficult to define, average reading level, or a person’s comprehension abilities, is not.

Turning to Twitter, we’ve used a computer algorithm to score tweets based on spelling, grammar and word choice.

Studying each city and county right across the UK, we have examined the reading levels of over 100,000 Twitter messages posted by users within the boundaries of each area.

What exactly did we look at?

  • Grammar
  • Spelling
  • Style
  • Flesch Reading Ease
