Number of shootings by Year

This chart was compiled using the data set of the number of shooting incidents reported on school campus, K-12, college and universities from 1850 until mid-2018, shown in red. In green is the population in millions taken from census data.

The number of shooting incidents shows a disturbing upward trend, with both the National Firearms Act and the Gun Free School Zone Act predating the exponential rise in incidents in this century.

Population growth shows a nearly linear expansion during this same time period. No correlation with population data could be found with the number of shooting incidents on school campus.
