DataTown allows you to download the underlying data as well. And we've just added a new feature - the ability to create graphics that compare communities! We built DataTown for you so check it out, and email us with what you loved and how we can make it better.

TODEX & Residensity

TODEX is short for Transit-Oriented Development Explorer. Developed in 2019, this tool allows you to review densities at all 261 Greater Boston transit stations and picture the great opportunity we have to build more housing near transit. An accompanying research brief estimates that 250,000 more housing units could be added if we boosted the median density around all stations from 6.2 to 10 homes per acre. In 2023, we expanded on the TODEX methodolgy by launching Residensity. This allows users for the first time to do analysis for any parcel in Massachusetts by individual property or by neighborhood.

Policy Archive

To foster a deeper understanding of housing and its relationship to economic growth, we maintain a library of resources which including our own reports, recent news releases and related studies and articles on housing and growth from around the U.S.
