We have estimated the size and location of undocumented residents in New York City down to the census tract level. These estimates are available in sum and split by country of origin.

We have a custom interactive map — along with descriptive methodology if you'd like to replicate our method — available for anyone to use upon request.

Do you have good use for our data? Email us! We don't bite.


This tool is the product of a class project at NYU CUSP, Spring 2014.
