New York City is broken up into 51 City Council Districts. Republicans currently hold 3 of them – districts 50 and 51 on Staten Island, and 32 in Queens.
I’ve estimated the percentage of the vote Clinton, Trump and others won in 2016 using the CCD and precinct shapefiles. This may not be perfect, as the shapefiles are not perfect, and I had to allocate precinct fragments to the larger entity, which might not be correct. However, as you can see on the map below the jump, according to my estimates, Trump won 4 NYC CCDs – Republican-leaning 50 and 51 on Staten Island and the heavily-Orthodox Jewish 44 and 48 in Brooklyn:
Note that Trump did not win Eric Ulrich’s CD 32 in Southeast Queens. In fact, as the charts below show, he lost it 38%-60%:
I can’t find the 2012 precinct-level results, but the 2008 results, based on a shapefile analysis of the VTD estimates from Dave’s Redistricting App versus the 2013 NYC CCD shapefile lines appears to be similar – McCain won the same 4 current NYC CCDs. These results, however, are fraught with even more potential estimation errors, as I could not fully reconcile the total vote to CCDs. The 2008 map is below:
Finally, I’ve made a map of the predominant racial group residing in each CCD, as of the 2010 Census. This is based on archived data from the NYC entity responsible for redistricting, so it should be accurate:
Note that Trump didn’t even come close to winning in many of NYC’s non-Hispanic white plurality and majority districts.
I’m sure those posters who are more familiar with NYC geography than I am can add more analysis. I can also add more maps (like the overall percentage of votes won by a particular candidate in each NYC CCD or percentage of a particular racial group in each NYC CCD) upon request.
