About SF 311 Predictions

Why we built this:

The San Francisco 311 service is an important bridge between citizens and our government. In a small way, it allows us to feel empowered and heard and capable of improving our city. This was a natural draw for our team.

We also love data. It can tell stories, illuminate problems, rally people around causes, and much more. We know that the SF311 dataset reflects a rich, interesting political and social landscape and we want to tease meaningful inferences from the data.

Also, we hope that our analysis will have utility to the City government, and that some of the information we discover will help them operate more transparently and efficiently.

How we built this:

The site you're viewing is a simple Flask application using Bootstrap and deployed on Heroku. For information about the prediction and machine learning available on SF311.info, please see the How it Works page.

How you can help:

  • Do you have a burning curiosity to see if ____ impacts ticket resolution?
  • Do you have an explanation for one of our insights or a related anecdote?
  • Do you know someone who works for the city that should see this website?
  • Do you see a bug?
Please send us an email or open an issue on Github.
