Measure of America, a program of the Social Science Research Council (SSRC), is in the process of revamping DATA2GO.NYC, a free, easy-to-use online mapping and data tool that brings together federal, state, and city data on a broad range of issues critical to the well-being of all New Yorkers. The revamp will include updated data in addition to a redesign to ensure DATA2GO’s continued usefulness to people and organizations requiring easily accessible and understandable data on well-being, equity, needs, and resources to address those needs in NYC.

We are interested in the civic community’s input into this redesign and would love to hear your thoughts to help us help you measure what matters for community well-being. The event will begin with a description of the project roadmap and proceed to breakout rooms, polls, and other sharing opportunities to ensure that all attendees have a voice in contributing their thoughts and ideas to the DATA2GO redesign. Attendees will be acknowledged on the DATA2GO site in appreciation of their time. We hope to see you there!

This redesign effort is informed by a diverse advisory panel and is supported by the Leona M. and Harry B. Helmsley Charitable Trust, the original funders of DATA2GO.NYC.

The health data resources on the New York City Health Department website can help you incorporate data into research, planning, or evaluation. Learn how to access and use Health Department data from the experts who work on these public-facing data resources!

New York City agencies create and publish a huge volume of geospatial data each year. We use geographic information systems (GIS), computer-based tools to store, visualize, and analyze this geographic data. This panel will review publicly available tools and data sets, discuss the state of GIS technology in the city, and consider how the City uses geospatial data to serve NYC residents. Join this conversation with agency GIS leaders about new maps & tools, geospatial data, and initiatives for 2024.


  • Lee Ilan, Mayor’s Office of Environmental Remediation (moderator)
  • Matt Croswell, NYC Department of City Planning
  • Josh Friedman, NYC Emergency Management
  • Chris Gettings, NYC Department of Health & Mental Hygiene
  • Carlos Piedad, Mayor’s Office of Climate & Environmental Justice

The Mayor’s Office of Climate & Environmental Justice (MOCEJ) will introduce and provide a live demonstration of the soon-to-be-released Environmental Justice NYC (EJNYC) Mapping Tool.

This exciting new tool allows users to view and interact with a wide variety of data layers to better understand the distribution of environmental burdens and benefits across the city on a neighborhood-by-neighborhood level. Over 100 datasets related to environmental justice concerns have been compiled and processed into a single platform, providing access to information and data that can help community-based organizations and residents advocate for the best outcomes in their communities.

MOCEJ staff will also give an overview of the City’s first-ever Flood Vulnerability Index (FVI), which is making its debut in the EJNYC Mapping Tool. Similar to the City’s Heat Vulnerability Index (HVI), the FVI quantifies and maps vulnerability to flood hazards. The FVI reflects each of the three components of vulnerability: exposure to a hazard, harm from the exposure, and capacity to recover (Cutter et al 2009). It demonstrates how these dimensions of vulnerability are distributed across areas that have different social, political, and economic capacities to guide policies and programs to address vulnerability to multiple sources of flooding in the city.

This event is open to all, no prior expertise is required! The EJNYC Mapping Tool is meant to be a useful and accessible resource for all. If you are interested in environmental justice, climate justice, pollution reduction, or public health, we encourage you to attend!

Rats in NYC are widespread, as they are in many densely populated areas. As of October 2023, NYC dropped from the 2nd to the 3rd place in the annual “rattiest city” list released by a pest control company.

Join Dr. Jun Yan and data science students from the University of Connecticut for presentations that delve into the presence of rats in the city, including a detailed analysis of city-wide rat sighting and rodent inspection data from the City’s Health Department. The student’s work includes descriptive statistics and visualizations of rat sightings across the city. The maps will be further analyzed to uncover correlations between rat sightings and various factors, including sociodemographic profiles, housing characteristics, and the physical landscape of the city. Additionally, we will share our investigation into the broader impact of rat sightings on other civic functions within NYC, like restaurant inspections, by integrating other NYC Open Data sources.

This engaging and informative workshop will be conducted by a selected group of students from the University of Connecticut, enrolled in the Introduction to Data Science course. These students have completed this work as part of their midterm assignment. They will show the results from their analyses as well as the Python code that generated the analyses. The workshop is open to anyone who is interested in urban challenges or data science.
