Robbery trends in Troy show a consistent pattern of zero incidents from 2010 to 2022. This absence of robberies has remained stable despite fluctuations in population. The robbery rate per 1,000 people has stayed at 0, and the city has not contributed to the state's robbery statistics during this period. The lack of robberies suggests a community where property-related violent crimes are exceptionally rare.

Aggravated assault has been the most prevalent form of violent crime in the city. The number of aggravated assaults fluctuated over the years, with peaks of 6 cases in 2010 and 4 cases in 2014, 2016, and 2022. The rate per 1,000 people varied accordingly, reaching a high of 5.06 per 1,000 in 2010 and 3.78 per 1,000 in 2022. The city's contribution to the state's aggravated assault cases has also varied, peaking at 0.72% in 2010 and ranging between 0.06% and 0.4% in subsequent years. This suggests that while aggravated assault occurs more frequently than other violent crimes, it remains relatively low compared to state levels.

Examining correlations between violent crime trends and other factors reveals some interesting patterns. There appears to be a weak inverse relationship between population density and violent crime rates. For instance, in 2010, when the population density was at its highest (1,400 per square mile), the city experienced its peak in violent crimes (6 cases). Conversely, in years with lower population densities, such as 2019 (1,052 per square mile), violent crime rates were also lower (1 case). However, this correlation is not consistent throughout the dataset and should be interpreted cautiously.

Applying predictive models to forecast violent crime trends for the next five years (up to 2029) suggests a potential slight increase in aggravated assaults, which have been the primary driver of violent crime in Troy. Based on the historical data, we might expect to see between 3 to 5 aggravated assault cases annually by 2029. Other violent crimes, including murder, rape, and robbery, are predicted to remain at or near zero, consistent with historical trends.

In summary, Troy, Montana has maintained relatively low violent crime rates over the past decade, with aggravated assault being the most common form of violent crime. The absence of murders and robberies, coupled with only isolated incidents of rape, paints a picture of a generally safe community. However, the fluctuations in aggravated assault cases highlight the need for ongoing community policing efforts and violence prevention programs to maintain and improve public safety in the years to come.
