?The authors hypothesized that there is a positive relationship between income inequality and

mass shootings. Furthermore, these authors also hypothesize that mass shootings vary based on

regional locations. The authors of these articles aimed at extending the previous research that

finds stronger evidence regarding the positive relations between income inequality and mass

shootings. Authors of the study employed previous research that finds a strong positive

relationship between income inequality and mass shootings through examining the impact of the

family’s income and the association between inequality and income. In order to perform the

analysis regarding the effects of the family’s income and the interaction between inequality and

income, authors compiled data from 3,144 nations from 1990 to 2015. The outcome of this study

indicates that even though the income inequality and income alone are the predictors of the mass

shootings, the impacts of mass shootings are stronger when combining via interaction. The

results also show the highest number of shootings are those that combine both high levels of

inequality and high levels of income. To handle the epidemic issue of mass shootings, it is

important to have a clear understanding of how to tackle the rise in inequality and unstable

environments which leads to the existence of inequality.?This study is important since it gives

some of the reasons why there are high incidences of a mass shooting in some regions as

compared to others. Therefore, it gives a direct solution to ensure that there is equal distribution

of resources and equal employment opportunities to ensure that the issue of mass shootings is

dealt with. This study also indicates that effective solutions to mass shootings need to involve the

understanding of the main causes of mass shootings.
