The Stanford Geospatial Center has created this site to help people analyze the data related to the mass shootings in the United States over the past few decades.
Mass Shootings in America
This website has been built by the Stanford Geospatial Center with the purpose of understanding the history of mass shootings in the United States over the past few decades. It is hoped that by presenting the data in visual form patterns may emerge that can be studied to help prevent future tragedies and that this information contributes to the national debate.
These data are not comprehensive and many questions remain as to what to include on the site. The names of all shooters have been removed from the maps and data, the pertinent information about them such as age, sex, history of mental illness, and possible motive remain. We will continue to build out this website with pertinent state and federal regulatory information related to firearms and will continue to add to the dataset to make it more complete.
The data, map and graphics are free and may be embedded on any website with proper attribution. Please contact us if you would like access to the dataset or have suggestions to improve the site.
