A Union-Tribune analysis examined data for nearly 500,000 stops conducted by the two largest law enforcement agencies in the county — the San Diego Police Department and the San Diego Sheriff’s Department. Combined, the two agencies made contact with some 560,000 people.

Nearly 20 percent of the stops made by San Diego police officers from July 2018 through December 2020 involved Black people, who make up about 6 percent of the city’s population.
