Open Source

The UBI Center open sources all our models

We open-source all our models at

There you can see our code, file issues we’re working on, and see how we’re progressing against those priorities.
All our work uses open-source projects and data. In particular, our Census data comes from the Open Source Policy Center’s Tax-Calculator project, and we use Python and Jupyter notebooks. We contribute to these projects whenever possible.

We leverage and contribute to existing open-source projects, and open-source our own analysis.

Tax-Calculator is an open-source tax analysis tool, which we use and contribute to.

Jupyter notebook calling functions from taxcalc and microdf to produce analyses.

We’re working on open-sourcing all our work, including this website. To help, email or let us know on GitHub.
