City of Change: Occupancy Density in Detroit's Residential Neighborhoods

Data Driven Detroit (D3)   (Detroit)

November 2014

In 2009, Data Driven Detroit (D3) participated in the Detroit Residential Parcel Survey (DRPS), collecting data on roughly 350,000 structures and vacant lots in the city of Detroit.  The survey captured information on the physical condition of Detroit’s residential neighborhoods and empty lots.  Eventually, passage of time rendered the DRPS dataset less representative of current conditions in the city and thus less useful for decision-makers.  In the winter of 2013, the Motor City Mapping project once again undertook the collection of parcel-level data in Detroit.  Using teams of resident surveyors and volunteer drivers, Motor City Mapping covered nearly 380,000 parcels in only six weeks of field work, providing information on structural condition and occupancy.   In addition, D3 incorporated more than twenty other datasets into Motor City Mapping, creating the most comprehensive property database ever for Detroit.

“City of Change” is a D3 blog series dedicated to using these newly available data to explore how Detroit has changed over the past five years. This third blog (the first two appeared o November 11 and 18) discusses changes in occupancy density in Detroit's residential Neighborhoods.
