A recent groundbreaking analysis conducted by researchers at NYU Tandon School of Engineering revealed that New York City is positioned in the top 15 percent of safest cities among over 800 cities in the United States. The study underscored the efficacy of the city’s initiatives in reducing homicides.
The research team, in a published paper, delved into the correlation between a city’s population size and the occurrences of gun-related homicides, gun ownership, and the presence of licensed gun vendors. Surprisingly, the study uncovered that these factors do not exhibit a linear relationship with population size. This implies that as cities grow in population, the rates of gun homicides, ownership, and availability of gun sellers do not increase proportionally in a straightforward manner across different cities.
To address this complexity, the researchers introduced a data analytics metric known as Scale-Adjusted Metropolitan Indicators (SAMIs). This measure effectively filters out the population effects, enabling a fair comparison between cities of varying sizes and facilitating a more nuanced analysis of the dynamics between firearm violence, ownership, and accessibility.
The senior author of the paper highlighted that the conventional approach of evaluating per capita rates of gun violence to assess the effectiveness of gun laws may not provide a complete picture. The SAMI analysis revealed that certain large cities with higher per capita gun violence rates might actually be more successful in mitigating gun-related harms compared to smaller cities with lower per capita rates.
Further analysis using SAMI demonstrated that firearm homicide and robbery rates tend to escalate disproportionately in larger cities like NYC. Conversely, gun ownership rates exhibit a sublinear scaling pattern, indicating that larger cities have fewer guns per capita compared to their smaller counterparts. The study attributed higher gun violence rates in densely populated cities to various contributing factors such as income disparities and population density.
The researchers also identified a correlation between rising homicide rates and increased firearm ownership, possibly driven by concerns for self-protection. Additionally, easier access to licensed gun sellers was found to directly influence gun ownership, with smaller cities having greater accessibility to such vendors.
The study’s findings challenged the common perception of New York City as unsafe, revealing that the city’s per capita homicide rates are significantly lower than expected based on urban scaling laws models. This suggests that NYC outperforms other major metropolitan areas in the country in terms of homicide prevention.
The research not only provides valuable insights into the dynamics of firearm prevalence and violence in the U.S. but also lays the foundation for future studies on a global scale to unravel the intricate dynamics shaping cities worldwide.
