PITTSBURGH-An interactive map of the Nov. 4 presidential election returns from Allegheny County voting districts is now available through the Pittsburgh Neighborhood and Community Information System (PNCIS), a joint project of the University of Pittsburgh's University Center for Social and Urban Research (UCSUR) and the Pittsburgh Partnership for Neighborhood Development (PPND). The map indicates the percentage of voter turnout, the total number of voters, and the percentage of voters supporting each candidate for every voting district in the county.

The election data are available on the PNCIS Web site at To use the map, click on the tool bar "Map Contents" and then the plus sign next to "Pub-Election" to see the data categories. Clicking on the plus sign next to each category will display a map key. Additional maps are available for previous elections.

According to the data, President-elect Barack Obama partly owes his victory to at least half-and up to 80 percent-of voters living in Pittsburgh and the bordering districts, from Penn Hills to Mount Lebanon. Districts further outside Pittsburgh strongly supported Republican contender Senator John McCain. The data also reveal that voter turnout in the red-leaning areas was generally higher by percentage and total number of voters than in districts in Pittsburgh. For example, no Pittsburgh district reported a turnout greater than 80 percent, and the only district in the county to have less than a 20 percent turnout was in the city.

PNCIS is an information system that collects integrated information on community conditions and provides it to local stakeholders. UCSUR operates the PNCIS in agreement with PPND, which was instrumental in securing the financial support to build the PNCIS and expand and develop it over the years. Other partners in the PNCIS include the City of Pittsburgh.
