Public Health & Safety: Evidence-Based Practice

Introduction

Public safety is one of the foundational standards of managing citizens’ needs, yet it is quite difficult to attain due to the multiple factors that affect public safety negatively. Ranging from health issues to disasters, threats to public safety are often uncontrollable and unpredictable (Purnell, 2018). However, with the adoption of innovative tools, the levels of safety can be monitored, which the latest tools for data visualization provide. Due to the ability to embrace an extensive amount of data and arranging it carefully, the data visualization by Law Enforcement Officers Killed and Assaulted (2019) (LEOKA) and the National Institute of Corrections (2019) (NIC) can be regarded as superior.

Goals and Key Insights

In order to produce a detailed account of changes in public safety and the impact of factors that define it, one needs to consider a huge amount of information and arrange it in a way that will be easy to perceive and understand by an average user. Herein lies the secret of LEOKA’s success in managing public safety data (). Despite containing very diverse information and incorporating a vast array of facts about public safety and the threats to it, the data sets organized in charts and maps are fully clear and accurate (). The use of a three-color scheme in the map to delineate the type of murder was quite effective. For the same reason, the NIC dataset was deemed as excellent since the agency has managed to map the key information to visualize it in the best way possible.

Conclusion

Deploying different types of data visualization is critical when addressing public health concerns since none of the methods allows illustrating every aspect of particular concern. In the case under analysis, diagrams allow showing the general trend in the levels of violent crimes, whereas the application of color maps delineates the areas that require particularly strong concern. Therefore, the information provided by LEOKA and NIC can be seen as very valuable for managing violent crimes in the U.S.
