New York City publishes thousands of datasets about how the city actually works — and anyone can explore them for free.

We’re talking 311 complaint records going back over a decade. Every restaurant inspection grade in the five boroughs. Real-time subway performance. Tree inventories (yes, the city has counted every street tree in NYC — twice). Exposed vehicle collision data. Building permits. Dog licenses. Film shoot locations. Air quality readings block by block.

It’s a massive, fascinating, sometimes weird collection of data — and most New Yorkers have no idea it exists.

What We’ll Do

In this workshop, we’ll get hands-on with the NYC Open Data portal’s built-in explorer. No code, no downloads, no setup. Just a browser.

  • Find datasets — Learn how to search and browse the portal to find data that interests you
  • Explore in the browser — Use the portal’s built-in tools to filter, sort, and visualize data right on the site
  • Ask questions — We’ll dig into a real dataset together and show how to go from “I’m curious about…” to actual answers
  • Understand what you’re looking at — Column names, data types, update frequencies, and how to tell if a dataset is actually useful

Some Things You Might Want to Look Up

  • Which block in your neighborhood has the most 311 noise complaints
  • How your local restaurant scored on its last health inspection
  • Whether traffic injuries are going up or down on your commute route
  • How many dogs are registered in your ZIP code (and what breeds)
  • What films have been shot on your street

What You’ll Need

  • A computer with a web browser
  • That’s it

No coding. No spreadsheets. No experience necessary. Just show up curious.
