Boundaries, Districts, and Zones in New York City: Political Districts

This guide covers how to find cartographic materials related to the internal boundaries, districts, and zones of New York City.

Political Districts

Within New York City, there are a number of districts that are zoned for various political offices. Using maps to get a better understanding of these political divisions within a neighborhood, you can answer questions like:

  • How has this political district's boundaries changed over time?
  • Who has represented this political district?
  • What is this political district typically affiliated with?

To answer these types of questions, please see below for examples of the different political district types.

  • Election District: A district that is created to administer elections. Sometimes referred to as a voting district or electoral district. 
  • Assembly District: Elected representatives that represent a district serve a two-year term at the NYS Assembly - the lower house of the NYS Legislature.
  • Senatorial District: Elected representatives that represent a district serve a two-year term at the NYS Senate - the upper house of the NYS Legislature.
