The cluster categories were high-high, low-low, low-high, high-low, nonsignificant, and missing. Both data sets had a significant high-high cluster in the Southeast (Alabama, Louisiana, and Mississippi in GVA; plus Arkansas and Tennessee in CDC data), but when the 2 datasets were compared, the rate differences were nonsignificant. There was a significant low-low cluster in the GVA data set in the Northeast (Massachusetts and Vermont); however, data suppression in CDC WONDER did not allow for evaluation of a similar cluster in the Northeast. — Cluster maps of the spatial dependency of gun violence mortality rates across the contiguous United States, by state, in 2017 in 2 data sets: the Centers for Disease Control and Prevention (CDC) Wide-ranging OnLine Data for Epidemiologic Research (WONDER) database (1) (panel 2a) and the Gun Violence Archive (GVA) (2) (panel 2b). Panel 2c shows the rate differences between the 2 data sets. Population data are from the US Census Bureau (3). Local Moran’s I (4) was used to calculate mortality rate differences between the states. States with missing data were suppressed because of small numbers in CDC WONDER.
