COVID-19 changed people’s lifestyles all over the world. This event will focus on analyzing resident housing property sales data in New York City from 2019 to 2023, before, in, and after COVID periods. By examining trends in sale prices, property characteristics, and neighborhood differences, this analysis aims to uncover key insights into the residential real estate market. Furthermore, machine learning techniques will be applied to predict property values and classify neighborhoods based on various factors such as location and building type. An end-to-end data pipeline process will be demonstrated in this talk (data collection, wrangling, visualization, feature engineering, machine learning modeling) via the python notebook.

Join Columbia’s Center for Spatial Research and Stamen Design as they introduce Mapping Historical New York (mappinghny.com), a tool and data resource that provides Census data from 1850 to 1940 at the individual level. The Digital Atlas breaks new ground by locating each person counted in the Census at their home address, sometimes before the street grid was even established. This is a living project that will expand to include all five boroughs up to the 1940 census. Learn how the data were created, how to use the tool, and download the data to make your own maps.
Join us for an exciting set of back-to-back presentations featuring Cornell Tech researchers and practitioners as they share their real-world applications of NYC Open Data.

This event is part of an Open Data Week series hosted by Cornell Tech on Wednesday, March 26 from 5-8pm. We’d love for you to join us for both sessions— though it is not required! We’ll kick off at 5:00 pm with a hands-on Discovering NYC Open Data class from the Open Data Ambassadors, where you’ll learn the fundamentals of NYC Open Data. Following that, at 6:30 pm, Cornell Tech researchers and experts will discuss their real-world applications of open data, during Open Data in Action: Driving Academic Research and Government Collaboration at Cornell Tech. Join us for a post-event happy hour next door at Anything at All!
There are many easy ways to get to Cornell Tech, located on Roosevelt Island. For maps and directions see here.
NYC School of Data is a community conference that demystifies the policies and practices around open data, technology, and service design. This year’s conference helps conclude NYC Open Data Week and features 30+ sessions organized by NYC’s civic technology, data, and design community! Our conversations and workshops will feed your mind and inspire you to improve your neighborhood.
To attend, you need to purchase tickets. The venue is accessible, and the content is all-ages friendly! If you have accessibility questions or needs, please email us at schoolofdata@beta.nyc.
Thank you to Reinvent Albany and Esri for helping to cover conference costs and making it possible to meet in 2025.
And If you can’t join us in person, tune into the main stage live stream provided by the Internet Society New York Chapter. Follow the conversation #nycsodata on Bluesky.

This presentation will showcase the technical aspects of the Property Tax Forecasting included in New York City Council’s Economic and Tax Forecasting Report. The event will include an introduction to the revenue unit team, fundamentals of the property tax system, and the data collection and the forecasting model used. This report gets published by the New York City Council as part of the budgetary oversight three times a year.
The presenters are Dilara Dimnaku, Chief Economist at the New York City Council and Andrew Wilber, Supervising Economist at New York City Council Finance Division, Revenue Unit.
This event will be beneficial to other data science and analytics teams that are using similar data sources by providing use cases along with domain knowledge in housing and tax related administrative data. Participants will be able to ask questions at the end of the presentation.
- How confidently can we predict the impacts of zoning change on housing supply?
- Can we use AI to create novel datasets that may allow us to better understand housing phenomena?
- What would it take to model a reality in which we build 1 million housing units?
These were some of the questions that led Janita Chalam, an independent researcher with a background in software engineering and machine learning, to begin their research journey into discovering how open data, statistical modeling, and AI can help us tackle the housing affordability crisis.
This presentation will walk through what Janita has learned about the variables at play in NYC’s housing landscape and present a statistical analysis of the Bloomberg-era upzonings as a case study in examining the frictions to building more housing in NYC.
Finally, Janita will propose some ideas for what kind of data and methodologies we might need in order to make bolder claims about what it takes to get us out of the housing crisis. By the end of this talk, we will hopefully have a better understanding of the role that data and empiricism can and should play in our conversations about housing policy.
This talk is for anyone interested in housing affordability and will not require any expertise in the technologies mentioned.
Join nonprofits JustFix and University Neighborhood Housing Program (UNHP) for a virtual presentation on how they used open data and open-source community tools to build a dashboard that supports tenant organizing in buildings impacted by the collapse of Signature Bank.
Signature Bank financed some of the city’s worst slumlords for years, underwriting their unscrupulous business practices premised on neglect, displacement, and deregulation of rent-stabilized apartments. The bank collapsed in 2023 and the FDIC took over the mortgages for 2,000+ buildings with over 30,000 units of rent-stabilized housing. This changed the incentives to make it possible to hold landlords accountable and allow tenants to use their power in new ways to get meaningful repairs made and even take control of their buildings through collective ownership models.
Ana Peña (Community Research & Data Analyst at UNHP) and Maxwell Austensen (Software Engineer at JustFix) will share the background on Signature Bank and opportunities presented in the wake of its collapse, how they worked with various stakeholders to guide the project, how they used open data and open-source tools to create the data dashboard, and how tenants, organizers, and other groups are utilizing the dashboard to build power and improve housing conditions.
This presentation is open to all, requires no specialized knowledge or skills, and might be most relevant to:
– NYC tenants interested in the situation with Signature Bank and how data can support organizing
– Government agency workers interested in seeing how their open data can be used for good.
– Civic tech enthusiasts interested in ways to access and utilize open data in new ways.
