The new National Officer-Involved Homicide Database (NOIHD), developed by the USC Dornsife Center for Economic and Social Research (CESR) and available to researchers and the public, is providing fresh insight regarding fatal encounters with police.

"Most research regarding homicides is based on data aggregated from a state or county," said Brian Finch, a researcher with CESR who led development of the database for more than three years. "We built the NOIHD to better understand the factors that may be related to deadly police incidents, such as the education and training requirements of officers, at a more micro level."

NOIHD data also includes whether the deceased was armed or not, the department that autopsied the deceased, municipal debt, and officers killed on duty. Sources of the data include , the FBI, U.S. census data and state governments.

"Officer-involved " refers to any death involving a , whether intentional, such as an officer shooting a suspect, or unintentional, such as an officer accidentally dropping a gun that then fires and kills someone.

The NOIHD supplements publicly available data available from the Fatal Encounters website, the most comprehensive online database of officer-involved homicides. Developed and managed by journalist D. Brian Burghart, who is now a research associate with CESR, Fatal Encounters includes the location of the homicide, cause of death, the poverty level of the area in which the killing took place, and the race and age of the decedent, as well as a brief description of the deadly incident, if available.

Finch, a professor of sociology and spatial sciences at USC Dornsife College of Letters, Arts and Sciences, says some preliminary findings (that have not yet undergone peer review) were unsurprising. "For example, departments that require officers to have more training and higher levels of education tend to have lower levels of homicide," he said.

What was surprising to Finch is that officer-involved homicides seem to be increasing faster in suburban and than in cities. His research also indicates that deadly incidents with the police seem to be less likely to show up in official sources if the medical examiner or coroner was overseen by the sheriff's department rather than another county department.

"In fact, two coroners in San Joaquin County resigned because they said the sheriff's department pressured them to report deaths as not being unrelated to law enforcement, when they clearly were," Finch says.

Finch is familiar with research that shows that when there's municipal debt, become more active in policing , imposing more frequent traffic and other fines. He plans to investigate whether there's a correlation between municipal debt and officer-involved homicides, which may result from over-policing. He and his colleagues are also exploring the effects of neighborhood gentrification on officer-involved homicides.
