By the numbers: In the last month — counting the week even before the movement began with Floyd’s killing — there were 1.04 billion social media interactions (likes, comments, shares) on stories related to police conduct, police reform, racial inequality, Black Lives Matter and the cases of George Floyd, Breonna Taylor and Ahmaud Arbery.

That’s far more than the next biggest social change movement over a 28-day period during the Trump era: the fight for gun control following the shooting at Marjory Stoneman Douglas High School in Parkland, Fla. in February 2018. That event drew 153 million interactions.

The third biggest was the backlash to Trump administration immigration policies in June and July 2018, including ICE practices and family separation (121 million interactions).
