Resurgent attention to past victims of police violence following George Floyd’s death and other periods of interest to Black Lives Matter.

We consider four periods of spikes in attention relevant to #BlackLivesMatter: November 24th–December 8th, 2014 (Deaths and non-indictments in the cases of Michael Brown, Tamir Rice, and Eric Garner), July 13th–July 26th, 2015 (death of Sandra Bland), July 5th–July 13th, 2016 (deaths of Philando Castile and Alton Sterling), August 12th–August 22nd, 2017 (“Unite the Right” Charlottesville rally), and May 25th–June 6th, 2020 (death of George Floyd). The number of names that received increased attention during a spike period is reported, as well as the percentage of those that had not received any measurable attention in the 30 days prior to the spike. The average change in average relative frequency is calculated for the difference between 30 days before the spike period and during it, and 30 days before and after it. Statistical significance is indicated by * for α = 0.05 and ** for α = 0.01.
