As the votes come in for the New York state presidential primary, we're watching how the candidates fared in New York City neighborhoods.

Motivation and Methodology

Our aim was to provide a picture of which parts of the city voted for which candidates — particularly in the Democratic primary, since Democratic primary voters vastly outnumber Republican primary voters citywide.

From a conversational standpoint, it makes sense to count votes by neighborhood. From a computational standpoint, that's tricky to do, because the precise boundaries of New York City neighborhoods are notoriously difficult to define.

We settled on New York City's map of Neighborhood Tabulation Areas, which is imperfect but divides the city into roughly equal population chunks. Votes are counted and sent to us via the Associated Press by New York City election districts, which tend to span just a few blocks. We calculated which election districts fit into which Neighborhood Tabulation Areas. Where districts straddled two or more neighborhoods, we placed them in the neighborhood in which they had the most square area. We renamed "North Side / South Side" to "Williamsburg" and "Williamsburg" to "South Williamsburg" for clarity.

The city combines the votes of some districts into one "parent" district, so we assign all of those votes to the parent's neighborhood. 

The boundaries in the map above follow the contours of election districts we've put in the same neighborhood given these rules, which means that a few of the neighborhood outlines get a little funky.

We've also clipped out water, parks, airports and cemeteries, and dropped election districts where the city Board of Elections reports no registered voters.
