From the Introduction: "In 2020, a year defined by the COVID-19 [coronavirus disease 2019] pandemic, the crime rate in California's 72 largest cities declined by an average of 7 percent, falling to a historic low level. From 2019 to 2020, 48 cities showed declines in Part I violent and property felonies, while 24 showed increases. The 2020 urban crime decline follows a decade of generally falling property and violent crime rates. These declines coincided with monumental criminal justice reforms that have lessened penalties for low-level offenses and reduced prison and jail populations."
