Robbery rates in Filer have remained at zero for the entire period from 2010 to 2022. This consistent absence of robberies, even as the population increased, indicates a very low risk of this type of crime in the community. The city's contribution to state robbery statistics has consistently been 0%, further emphasizing the rarity of this crime in Filer.

Aggravated assault has been the most prevalent form of violent crime in the city. The number of cases fluctuated, with notable peaks of 7 cases in 2011 (1.36 per 1,000 people) and 6 cases in 2018 (1.02 per 1,000 people). The most recent data from 2022 shows 2 cases (0.31 per 1,000 people). The city's contribution to state aggravated assault cases has varied, peaking at 0.46% in 2011 and most recently at 0.08% in 2022. This trend suggests that while aggravated assault remains a concern, its prevalence relative to the population and state figures has generally decreased over time.

There appears to be a correlation between population density and violent crime rates in Filer. As the population density increased from 5,058 per square mile in 2010 to 6,258 per square mile in 2022, there were fluctuations in violent crime rates. However, the relationship is not straightforward, as periods of higher density did not always correspond to higher crime rates. For instance, despite the highest population density in 2022, the violent crime rate was lower than in some previous years with lower densities.

The racial composition of Filer has remained predominantly white throughout the observed period, with the white population consistently above 86%. There doesn't appear to be a strong correlation between changes in racial distribution and violent crime rates in this case.

Applying predictive models based on the historical data, it's projected that violent crime rates in Filer will likely remain low over the next five years, potentially averaging around 3-4 incidents per year by 2029. However, this prediction should be interpreted cautiously given the historical volatility in the data.

In summary, Filer has maintained relatively low violent crime rates despite significant population growth. The absence of murders and robberies, coupled with infrequent rape cases, paints a picture of a generally safe community. Aggravated assault remains the primary violent crime concern, though its prevalence has generally decreased relative to population growth. The city's contribution to state crime statistics has remained minimal across all categories of violent crime, further emphasizing its overall safety profile.
