2020 has been a killer year in every way, including murder. The United States has experienced the largest single one-year increase in homicides since the country started keeping such records in the 20th century, according to crime data and criminologists. The data collected so far is stark a 20.9 percent increase in killings nationwide, in the first nine months of the year, according to the FBI, and even bloodier increases in many major cities, due largely to gun violence. Homicides recorded by 57 U.S. police agencies found a 36.7 percent increase for a similar time frame, according to figures compiled by Jeff Asher, an analyst and consultant who studies crime data. "Like everything else in 2020, the crime data was a disaster. There was a huge spike in murder, and it's hard to say just how bad it is, but it's fairly clear we are going to see the largest single-year rise," Asher said. Experts agree the pandemic has played a huge role in the rise in killings, but it has also probably contributed to a significant decrease in nonviolent crimes, which the FBI data shows fell by more than 8 percent in the first nine months of the year, possibly because there were fewer people on the street. It's not just big cities that are seeing rising homicides. According to the FBI data, small cities with fewer than 10,000 residents saw more than a 30 percent increase in killings in the first nine months of this year " a data point Asher called "insane."the main resource for national crime data, the FBI, will not report final figures for 2020 until September 2021.
