Uber's surge-pricing algorithm in Washington D.C. was found to provide systematically worse service (longer wait times) to neighborhoods with higher percentages of people of color, even when controlling for income, poverty, and population density.
A Washington Post analysis of Uber data collected over four weeks (February 3 to March 2) from 276 locations in Washington D.C. revealed racial disparities in service quality. The analysis used Uber's API to collect wait time and surge pricing data every three minutes, focusing on uberX cars. The study found that census tracts with more people of color experienced longer wait times, with some areas like Congress Heights, Bellevue, Washington Highlands, and southern Southwest D.C. averaging almost seven minutes for an uberX ride. In contrast, majority white areas like Dupont Circle, Logan Circle, and Georgetown averaged just over four minutes. The disparities persisted even when controlling for household income, poverty rate, and population density. Areas with more people of color also experienced surge pricing less frequently (16-47% of the time), making them less attractive to drivers seeking higher earnings. The algorithm's design redistributes existing driver supply geographically rather than increasing absolute supply, creating a zero-sum situation where improved service in some areas comes at the expense of others. The analysis suggests this creates a negative feedback loop where poor service quality may reduce demand in affected neighborhoods.
