Data for Democracy

Data for Democracy's mission is to be an inclusive community for data scientists and technologists to volunteer and collaborate on projects that make a positive impact on society.

Who runs D4D?

The community does! Anybody who wants to contribute to making D4D better is highly encouraged to do so! Everything in D4D thus far has come from grassroots ideas proposed and pushed forward by a community member just like you and there's always more room for improvement. Whether it's starting a new project or proposing a new tool for the community to use, don't hesitate to just go for it!

Across the Community

While most of our work is project based, the community is large and vibrant enough that we're looking for common needs across projects that the organization can support. These are ongoing roles that can be time consuming, but are also essential to making the community helpful to our partners and a valuable experience for our volunteers.


All of our projects are doing some interesting data gathering and analysis that we regularly share with the world on our blog and our YouTube channel. If you'd like to help with this, ping @lillianj in Slack!


The community has grown to a point where there is a lot of activity and a steady stream of new volunteers, which is awesome! We could use more people who know about the various projects that are happening along with the skills of the incoming volunteers, and can both match people to projects (ideally, to specific tasks), along with routinely surfacing new opportunities to the broader community for folks to get involved at all skill levels. Ping @gecky in Slack if this sounds like fun to you!

Project Leads

You've probably noticed that there are a few people in every active project keeping the group on track, taking questions, and helping new folks get settled in -- that's by design. Leading a project can be a big time commitment, but it's hugely valuable to making sure we're doing useful work, and volunteers are getting the most out of volunteering. You don't need to be super technical, just organized and enthusiastic! Ping @mo in Slack if you're interested in leading a project.

City groups

Data for Democracy volunteers are all over the world, and many cities have dedicated channels in Slack, and even regular in-person meetups to collaborate in person and work on data projects specific to their city or state. This is mostly US-based for now, but that's not on purpose, so feel free to spin up a group where you live! (We're looking at you London, Berlin, Warsaw, Bangalore, Sydney, and...). And of course, if you are in the US, there are probably at least a few D4D-ers where you live, so don't hesitate to start your own city group!

Current projects

We have many projects going in our slack community. Below is a list of some of our more active projects that are actively seeking help.

Boston Crash Modeling

Project Description: This is an official collaboration between the City of Boston's Analytics Team and Data for Democracy. We want to build a crash prediction modeling application. This would combine things like our crowdsourced safety concerns dataset and crash reports with a wide range of other data from our own open data portal as well as from other sources like the state's transportation and transit agencies, weather conditions feeds, and traffic reports from sites like Google. The end result will be a set of dynamic predictions we can use to identify potential trouble spots and direct timely safety interventions--everything from protected bike lanes and better-marked crosswalks to new street lights and traffic light timings. We'll make this publicly-available to everyone through a hosted map application, and develop the project as an open source template that can be adapted for use by other cities.

Slack: #boston-crash-modeling

Project Leads: @therriault (City of Boston lead), @niccolley (Data for Democracy lead)

Election Transparency

Slack: #election-transparency

Project Description: Aggregating and normalizing county-level election results to be shared with the broader community. This team now has a fantastic dataset that's difficult to obtain. In addition to the ongoing data engineering effort, they could use help from statisticians, political scientists, and anyone ready to analyze this data.

Project Leads: @chris_dick, @scottcame, @rachelanddata


Immigration Connect

Project Description: Collecting, analyzing, and modeling data related to immigration. We're also building tools (visualizations, email parsers, matching algorithms to connect to connect pro bono lawyers with immigrants in need) to support the work of organizations working on immigration law and other immigration related issues.

Slack: #immigration-connect

Project Leads: @tylerjrichards @jtorrez @chavan
