While doing my research, and inferring that firearm ownership in households may not have a correlation with the amount of mass shootings occurring, I came across information that over 44 million Americans have mental health and substance use conditions. Since 2015, Mental Illness in the United States has worsened. Youth with severe depression has increased from 5.9% to 8.2% in 2015. 76% of youth are left with either insufficient or no treatment for their mental illness or condition. 56% of Americans with a mental illness do not receive treatment, which is a staggering fact to come across. When I investigated Mass shootings in the United States, majority of the suspects had mental illness conditions, which were either not treated or discovered by their friends and family. Several of them had fanatic ideologies involving patriotism in this country, and 70 % of suspects after opening fire committed suicide at the end of the mass shooting. This shows that mental illness is directly linked to the amount of mass shootings in the United States. In a recent study by CNN, the horrifying numbers of Mass Shootings in the United States may be caused by the “copycat phenomenal”, meaning that each Mass shooting inspires the next one. Many researchers believe that mass shootings are contagious; one mass shooting may increase the chances that another will occur within two weeks, known as an “infection” which can last for 13 days. Along with America’s mental illness conflicts among citizens, and the easy access to guns in the country, Mass shootings have increased, and may continue to increase even more after Donald Trump being in office to inspire false patriotism, as well as American soldiers returning home with PTSD. Results and Conclusion In conclusion, my analysis rejects my hypothesis. I hypothesized that the higher the percentage of households with firearms, the higher the number of people killed in mass shootings would be. Unfortunately, the graph does not fully agree with that hypothesis. The regression line is not steep at all, however it is increasing. Therefore, the two variables affect affect one another, however not very significantly. There are other variables that affect Mass shootings in the United States, and guns in households is not necessarily the factor affecting it. Mental Health, political situation, and the healthcare system are more of the contributing factors affecting Mass shootings in the United States.
