Bad Data

Real-world examples of how not to do data

Bad Data is a site providing real-world examples of how not to prepare or provide data. It showcases the poorly structured, the mis-formatted, or the just plain ugly.

Its primary purpose is to serve as an educational tool for governments and other organizations – though there may also be some aspect of entertainment.

It is also a good source of practice material for budding data wranglers—those tasked with cleaning and transforming data (in fact the repo in fact began as a place to keep practice data for Data Explorer).

What information to provide

What's we'd like to see in a good example is:

Optional (but desirable): a backup of the data in case it goes away! (If the file is more than ~100kb please provide a chopped down version illustrating the main "badness").

Also don't forget to credit yourself in an appropriate way (if you want to be credited!).

Lastly, note that your contribution will be licensed under this site's general CC Attribution License.

  4. Edit the ex/{your-slug}/index.md file

    • Change the frontmatter attributes (i.e. key/value items at very top of file) as appropriate
    • Add the description (markdown formatted) to the main section of that page
  5. Commit the new file
