Robbery cases remained at 0 for both 2017 and 2019. Similar to murder, this consistency suggests that robbery is not a prevalent issue in the city. The robbery rate per 1,000 people stayed at 0, and the city's contribution to the state's robbery cases remained at 0%.

Aggravated assault cases saw the most significant increase, rising from 1 in 2017 to 4 in 2019. This 300% increase resulted in the aggravated assault rate per 1,000 people rising from 0.27 in 2017 to 1.14 in 2019. The city's contribution to the state's aggravated assault cases also increased from 0% to 0.01%. This trend suggests a growing concern regarding violent confrontations within the community.

Examining correlations, there appears to be a potential link between the increase in violent crime and changes in racial demographics. The percentage of white residents increased from 49% in 2017 to 50% in 2019, while the percentage of Black residents decreased from 38% to 35%. Concurrently, median rent increased from $517 in 2017 to $493 in 2019. These shifts coincided with the rise in violent crimes, particularly aggravated assaults.

Applying predictive models to forecast violent crime trends, if current patterns persist, we might expect to see approximately 12-15 violent crimes annually by 2029. This projection suggests a continued upward trend in violent crime, with aggravated assaults likely to be the primary contributor.

In summary, Sumner has experienced a notable increase in violent crimes, particularly aggravated assaults, despite a decrease in population. The absence of murders and robberies provides some reassurance, but the rise in assaults and the occurrence of rape indicate growing concerns about public safety. These trends, coupled with demographic and economic changes, suggest a complex interplay of factors influencing the city's crime landscape. As Sumner moves forward, addressing these rising violent crime rates while maintaining its murder-free status will be crucial for ensuring the safety and well-being of its residents.
