The Digital Harrisburg project, in partnership with Messiah University, has compiled multiple data sets which include historical Census data, building footprints, and Sanborn maps. Geospatial processes were performed on each of these data sets and ultimately, an online interactive web map was constructed. The work done on Digital Harrisburg improved Census data, allowing a more accurate spatial analysis of the City of Harrisburg. As a result of the spatial analysis performed, trends of ethnicities and race movements across the city became apparent. This presentation will look at the population across Harrisburg from 1900 to 1930, exposing individual resident details such as race, immigration status and employment, and the patterns and trends of this population through time.
