NYC Election Maps is a website with interactive maps for elections within the five boroughs for which the Board of Elections made precinct-level results available.

These maps provide a unique way to find political and social patterns among communities throughout the five boroughs.

While some news outlets and academic organizations have mapped out high-profile races such as Mayor and Public Advocate, there haven’t been widely available maps using Election Districts (EDs) for smaller races such as Assembly, City Council or District Leader, among others.

This website provides a one-stop-shop to view mapped election results for many New York City elections within the past five years.


Where are the election results from? 
The City’s Board of Elections (BOE), which made these ED-level results publicly available on their website.

Why are older elections not available?
All maps use publicly released election results from the New York City BOE. Their website currently only shows results by Election District (ED) up until 2014. However, we are attempting to get pre-2014 ED-level results through FOIL requests and have already added some (see 2013 and 2009 Council races).

Why not map by Assembly District? 
Assembly Districts (ADs) are too large to properly delivery information of choropleth maps. For instance, an AD could include both very conservative and very liberal populations. With Election District (elsewhere and otherwise known as precinct), this is less likely due to the small district size.

Who is this website for?
Anyone who is interested in understanding communities and elections within New York City. This could include observers, candidates, consultants, journalists, academics and others.

How is opacity determined?
By the percentage of the winner. (Example: John (R) defeats James (D) in an election district with an 80-20 result. The district’s opacity would be 80 percent red.) Ties are displayed with a gradient. As a result, districts with lighter colors were more competitive while districts with darker colors were more heavily leaning towards one candidate.

Why are some EDs combined? 
Sometimes the BOE may choose to combine an ED with low turnout with a nearby ED for counting purposes. This is more common for special, primary and off-year elections where turnout is low and much less common for general elections in even-numbered years. 

Can I share screenshots of these maps?
Yes, but please make sure to also include a link to the map when sharing the image.
