(CNN) Here is a list of the deadliest mass shootings in modern US history (1949 to present).

Suicides, gang-related incidents and deaths resulting from domestic conflicts are not included. "Deadliest" includes shootings with 10 or more fatalities. Shooters are not included in fatality totals.

Because there is no universal definition of mass shootings or central database tracking them, this list is based primarily on media reports and may not be complete or representative of all mass shootings.
