DC Real Property Tax Sales Jennifer Hsu University of Maryland
“There’s a lot of data out there. But hardly any of it has been processed and turned into insight.” —JaidevShergill Source: “Turning Data Into Money”, L. Burkitt, Forbes.com
Background • Discovery of Tax Sale • Tax sale mechanism • Process
Data Sources • Cfo.dc.gov publishes properties subject to tax sale each year in pdf format • Internet Archive (www.archive.org) sometimes saves a copy even when DC does not • Files are in a slightly different format each year
Raw data • What is published is the tax owed on each property (square, suffix, lot), and owner of record • Not all lots can be mapped to the (completely wonderful!) GIS layers made available by dcgis.dc.gov • Summarized the tax obligation to the tax square
Web-based? • How best to present data to, say, the average resident of DC? • Constraints: • Attention span • Variable technology • Accessibility • Visual Presentation
Final Product • Layers, raw data, credits will be published here: http://www.umiacs.umd.edu/~kobi/aag
Thank You • DCGIS • Census Bureau • DC Tax Office • Internet Archives
