Referendum petition data examined

You may have noticed that on 23rd June 2016 the UK held a referendum about whether to remain as a member of the European Union.

When the result didn't go quite the way they wanted, some people participated in an online petition with the goal of having parliament consider re-running the referendum to try to obtain a more significant resulting margin.

The apparent popularity of the petition attracted attention on social and conventional media, so I decided to take a look at the data.

There isn't a lot of information that is exposed, basically a breakdown of numbers by country of residence and a breakdown of numbers by constituency.

By loading the data into an application and sorting it and printing it out I noticed something conspicuous - Vatican City showing up as one of the most popular countries of residence.

Hold on, isn't that one of the least populated countries in the world?

Sure enough, the numbers involved exceeded the public stats of the total population - that literally didn't add up.

Myself and a few others flagged this up on Twitter, so the relevant parties did some checks and figured out how to filter out dodgy data and block later attempts at automated contributions.

My code is available on github.  By looking into the Git history you can see for yourself how the data for country counts changed over time.

The code for the petition site itself (not by me) is also on GitHub:
