According to CNN reporting on a Mother Jones study white perpetrators of mass shootings broadly follow the proportion of the white US population. Black and Asian perpetrators are slightly higher than their respective population share.
According to data compiled by Mother Jones magazine, which looked at mass shootings in the United States since 1982, white people -- almost exclusively white men -- committed some 64% of the shootings
Black people committed close to 16% of the mass shooting Mother Jones looked at, while Asians were responsible for around 9%. People identified as either Latino, Native American and unknown rounded out the study
Whites make up about 63% of the U.S. population, blacks 13%, and Asians 5%, according to the latest census numbers. Latinos account for some 17% of the total population
