You don’t usually associate spreadsheets and dashboards with justice. But you should.
Because behind every budget line, every policy, every new law—there’s a story about who gets what, who’s left out, and whether anyone will be held accountable. In the real world, data isn’t just numbers on a screen. It’s power. And when that power is used to serve the public, the rules change.
That’s why transparency matters. Not because it sounds good in a report, but because if people can’t see how a decision was made, they won’t—and shouldn’t—trust it. Reproducible analysis isn’t a technical feature. It’s how you keep the process honest.
So when we sat down with Alaa Moussawi, Chief Data Scientist at the NYC Council, we weren’t just curious—we were moved. His team isn’t building tools for vanity metrics or quarterly dashboards. They’re making data work for the people who need it most. Quietly. Deliberately. Without the hype.
The New York City Council isn’t just a policy-setting body—it’s the legislative branch of the city government, responsible for drafting laws, approving budgets, and overseeing agencies. It’s essentially the city’s Congress.
Alaa’s team plays a pivotal role in helping the Councilmake evidence-based decisions. His work spans two disciplines: one half focuses on advanced data science, the other on building the custom software systems that power everything from legislative drafting to constituent services.
And it’s all done with a surprisingly lean team: about a dozen data scientists and ten software engineers managing tools for over 50 council members and their staff.
This team doesn’t just report on data—they use it to influence real-world outcomes.
Take NYC’s pay equity analysis. Alaa’s group worked with city datato analyze salaries across race, gender, title, and experience for every public employee in the city. The result was a robust statistical study, made publicly available and peer-reviewable, aimed at driving meaningful policy.
Or consider the gun violence reduction initiative known as Cure. NYC has spent nearly half a billion dollars on this program since its inception. Alaa’s team applied spatial modeling to assess whether gun violence behaves like an epidemic—spreading from one area to another—and found evidence supporting the intervention’s public health framing. But more importantly, they were able to verify that the funds were well spent, demonstrating through a cost-benefit analysis that the city was reaping 6.5x what it paid in benefits.
What stood out wasn’t just the sophistication of the analysis—it was the transparency behind it. The team publishes code to GitHub, shares preprints, and stress-tests their results with robustness checks before drawing conclusions. Their goal isn’t speed. It’s trust.
This commitment to openness extends beyond the team.
NYC’s Open Data Law, originally drafted by the Council, mandates that city agencies publish datasets for public use. Alaa’s team goes further, building internal tools—like demographic dashboards and paperless hearing systems—that make these datasets actionable for Council staff.
These tools aren’t just about convenience. They enable fact-based legislation, especially when geography and population estimates don’t align neatly with political boundaries. By re-aggregating census data using building footprints and population density models, the team gives lawmakers an accurate view of their districts—without waiting on outdated or misaligned third-party data.
Alaa’s team builds almost everything in-house. From community voting tools to CRM systems and hearing software, their stack is open source—Postgres, Python, R, Django, React, and more. This isn’t just a budgetary decision. It’s a values-based one.
"Open source ensures reproducibility," he told us. "If we’re going to impact people’s lives, the analysis must be transparent, the software must be inspectable, and the results must be accountable."
That mindset stands in stark contrast to many private-sector deployments of machine learning, where results are often opaque, irreproducible, and unexplainable.
What makes Alaa's team exceptional isn't just what they build—it's how and why they build it. Theirs is a model of civic data work shaped by discipline, restraint, and a clear sense of responsibility.
One example? Despite assumptions that public agencies have easy access to vast datasets, the reality is often the opposite. "Having the right data to perform a great analysis requires the stars to align," Alaa told us. Data is often siloed, inconsistently reported, or unavailable due to legal and political constraints. That makes the work both harder and more important.
In response, Alaa’s team does more than build tools—they educate, enable, and elevate. They conduct internal trainings to help policy staff become smarter consumers of data. They advocate for more disaggregated data, knowing that better questions lead to better decisions.
And then there’s the engineering craftsmanship: one standout is a tool that allows analysts to recalculate population data across nonstandard geographic boundaries. By combining census estimates with building-level data, they can generate accurate demographic breakdowns at the council district level—unlocking insights where raw data alone falls short.
Even their use of AI shows intentionality. Years ago, before the rise of GenAI, the team built a vector-based search tool to check for duplicate legislative proposals. It isn’t flashy, but it is useful. And crucially, it is never allowed to make determinations. It is used as a tool, and the onus of fact checking the output remains on the end user.
Alaa didn’t start in public policy. He came from a physics PhD and spent time building machine learning systems at Los Alamos. But when he began working on civic data, he shifted gears—emphasizing statistics over machine learning, and transparency over automation.
Why? Because in high-impact settings, rigor matters more than novelty. And reproducibility builds more trust than velocity ever could.
Talking with Alaa was humbling. In a time when we're all too willing to hand the reins to algorithms we barely understand, it was refreshing—honestly, grounding—to see someone doubling down on clarity, accountability, and work that invites inspection, not evasion. No smoke, no mirrors. Just good data, good questions, and the kind of transparency that keeps the whole thing honest. That when data is applied thoughtfully, it can do more than just drive better business outcomes.
