evidence: The U.S. murder rate rose 30% between 2019 and 2020 – the largest single-year increase in more than a century, according to data published this month by the Centers for Disease Control and Prevention (CDC). The findings align with a separate tabulation of the nation’s murder rate published in September by the FBI. [...] The year-over-year increase in the U.S. murder rate in 2020 was the largest since at least 1905 – and possibly ever, according to provisional data from the CDC. (Final data is not expected to differ much from the provisional data.) There were 7.8 homicides for every 100,000 people in the United States in 2020, up from six homicides per 100,000 people the year before. The rise in the nation’s murder rate last year far exceeded the 20% increase measured in 2001, which was driven by the terrorist attacks of Sept. 11. Last year’s increase in the murder rate may have even exceeded the one measured in 1905, according to Dr. Robert Anderson, who oversees mortality statistics for the CDC’s National Center for Health Statistics. Anderson noted earlier this month that the 1905 increase was at least partly due to more states submitting data to the national death registry, as opposed to an actual rise in murders.
