CUNY Election Atlas Reveals Citywide Voting Trends

Where did Bill Thompson and John Liu draw more voter support than Bill de Blasio in 2009? Who fared better in key African American, Latino and Asian communities in the primaries and runoffs that year? And what do voting patterns over the last eight years suggest for the November mayoral elections?

The answers to these and other questions about voters’ choices at the polls are a click away at the NYC Election Atlas 2013, a joint project of the Center for Urban Research at the CUNY Graduate Center, the CUNY Graduate School of Journalism, and the Center for Community and Ethnic Media (CCEM).

The first part of the Atlas, a series of maps that reveal how four of the current mayoral candidates have fared, is already available.  The site will soon add dynamic tables of demographic data for ethnic populations citywide, voting statistics for these groups, neighborhood-level information, and interactive maps.

The Atlas maps election results for all the Democratic mayoral candidates this year who have run for citywide office since 2005. You can see how well (or not) four of the seven candidates ­– Thompson, Liu, de Blasio, and Anthony Weiner – fared in recent primary, runoff, and general elections for mayor, comptroller, and public advocate. The results provide historical and social context for the 2013 mayoral race.

The Atlas presents the voting data in a new way using two techniques. First, it maps election results by Census block, instead of election districts. New York City’s 5,300 election districts comprise of 30,000 inhabited city blocks. Mapping the information at this level reveals voting patterns as specific as block by block in some areas, whereas election districts often cover much larger areas.

Second, each map uses shades of color to visualize turnout as well as vote share to show not only how strongly voters in a given area favored a candidate, but also how well each candidate mobilized their voter base to go to the polls.

The Atlas offers filters for information such as voting trends by ethnicity/race, neighborhood, household type, household income and occupation.

Another filter maps by demographics the voter support for President Barack Obama in 2008 and 2012, and Gov. Andrew Cuomo in 2010.

The new data and maps will be topic of a September 4 half-day conference for journalists hosted by CCEM at the CUNY journalism school.

The free conference will begin with a discussion about the Atlas with staff members from the Center for Urban Research at the Graduate Center and followed by two panels, “The role of immigrant voters in the 2013 elections” and “Using data and maps to improve political coverage.”

Participants include Steven Romalewski, director of CUNY Mapping Service; Joseph Pereira, director of CUNY Data Service; professor Doug Muzzio from Baruch College; Sayu Bhojwani, founding director of New American Leaders Project; Steve Choi, executive director of New York Immigration Coalition, and Jaime Estades, director of the Latino Leadership Institute at Hunter College.
