Much research shows that there is a link between historic lynching in a community and contemporary issues such as housing patterns or incarceration rates. In this study, Probst and her colleagues analysed the association between a history of lynching within a county and the county's present mortality rates.

From the Equal Justice Initiative, the researchers obtained county-level data about the number of lynchings between 1877 and 1950 for 1221 counties in 12 Southern states. Counts were standardized to the 1930 population figures, then divided into four categories, from lowest (no lynchings) to highest.
