The robbery statistics for St. Francis mirror those of murder and rape, with zero incidents reported in both 2016 and 2018. The robbery rate per 1,000 residents is 0, and the city does not contribute to the state's robbery figures. This consistency in the absence of robberies is noteworthy, especially given the population changes.

Aggravated assault is the only violent crime category showing any incidents in St. Francis. In both 2016 and 2018, there was 1 reported case of aggravated assault. With the population decline, the rate of aggravated assault per 1,000 residents increased slightly from 0.53 in 2016 to 0.53 in 2018. The city's contribution to the state's aggravated assault cases remained constant at 0.02% for both years. This suggests that while the absolute number of assaults didn't change, the relative impact on the community increased marginally due to the smaller population base.

Examining correlations between violent crime trends and other factors, there appears to be a weak relationship between population density and aggravated assault rates. As the population density decreased from 2,202 per square mile in 2016 to 2,200 in 2018, the aggravated assault rate remained stable. The median rent increased from $560 in 2016 to $624 in 2018, but this doesn't seem to correlate strongly with the violent crime trends. The racial distribution remained relatively stable during this period, with the white population comprising 94% of residents in both years, showing no apparent correlation with crime rates.

Applying predictive models to forecast violent crime trends for the next seven years (up to 2029, which we'll present as five years from now), it's likely that St. Francis will continue to experience very low levels of violent crime. If the current trend holds, the city may continue to see approximately one aggravated assault per year, with the possibility of this number fluctuating between 0 and 2 cases annually. The rates for murder, rape, and robbery are predicted to remain at or near zero, barring any significant changes in local conditions.

In summary, St. Francis demonstrates a remarkably low and stable violent crime profile. The consistency in crime rates, particularly the absence of murders, rapes, and robberies, suggests a relatively safe community environment. The slight increase in the per capita rate of aggravated assault, due to population decline rather than an increase in incidents, warrants attention but does not indicate a significant deterioration in public safety. As St. Francis moves forward, maintaining these low crime rates while addressing the challenges of a shrinking population will be crucial for the city's overall well-being and development.
