Robbery trends in the city show minimal activity. From 2010 to 2018, there were no reported robberies. However, in 2019, there was a single robbery incident, which represented 0.03% of the state's total robberies for that year. This translates to a rate of approximately 0.54 robberies per 1,000 people in 2019, based on the estimated population of 1,850. In 2020, the robbery rate returned to zero. This isolated incident in 2019 does not indicate a concerning trend, given the overall low crime rates in the city.

Aggravated assault has been the most prevalent form of violent crime in Trimble. In 2010 and 2012, there was one reported case each year. The rate remained at zero from 2013 to 2017. However, in 2018, there was a spike with 4 reported cases, representing 0.02% of the state's total aggravated assaults. This spike translated to approximately 1.95 assaults per 1,000 people, based on the 2018 population of 2,053. In 2019, the number decreased to 1 case, or about 0.54 per 1,000 people, before returning to zero in 2020. These fluctuations, while noticeable in a small community, still represent very low overall rates of aggravated assault.

There appears to be a weak correlation between population density and violent crime rates. For instance, the spike in aggravated assaults in 2018 coincided with an increase in population density to 3,175 people per square mile, up from 2,900 in 2017. However, this correlation is not consistent across all years, and the overall low crime rates make it difficult to establish a strong relationship.

Applying predictive models to forecast violent crime trends for the next five years (up to 2029) suggests that Trimble is likely to maintain its low violent crime rates. Based on the historical data, we can expect the number of violent crimes to remain between 0 and 4 incidents per year, with aggravated assault being the most likely form of violent crime to occur. However, given the small population and infrequent nature of these crimes, any single incident could significantly impact the year-to-year statistics.

In summary, Trimble has maintained remarkably low violent crime rates over the past decade, with no reported murders or rapes, a single robbery in 2019, and sporadic cases of aggravated assault. The city's ability to maintain such low crime rates while experiencing population growth is noteworthy and speaks to the overall safety of the community. As Trimble continues to grow, maintaining these low crime rates will be crucial for the well-being and quality of life of its residents.
