Assignment 6 – Zhiyan Zhong

For this assignment, I looked into Mother Jones’s data of mass shootings, which are defined as shootings in public places in which four or more people other than the shooter died. As some people said that more guns linked to more mass shootings, I thought it would be interesting to put data about firearms ownership in the United States together with the mass shootings data and see if those two different datasets relate to each other. In the chart below, you will find the number of mass shootings and percentage of households owning one or more firearms in the U.S. from the year of 1999 to 2016.
