Robbery trends remained relatively low throughout the period. The city reported no robberies in most years, with single incidents in 2015, 2016, 2018, and 2022. The robbery rate per 1,000 people never exceeded 0.18 (in 2016). The city's contribution to state robbery statistics was minimal, reaching a maximum of 0.01% in 2022.

Aggravated assault showed the most variability among violent crimes. The number of incidents ranged from 0 in 2014 to a peak of 12 in 2017, which corresponded to a rate of 2.18 per 1,000 people. The city's contribution to state aggravated assault statistics was highest in 2017 at 0.02%. By 2022, aggravated assaults had decreased to just 1 incident, or 0.18 per 1,000 people.

Analyzing correlations, there appears to be a weak inverse relationship between population density and violent crime rates. As population density increased from 1,293 per square mile in 2010 to 1,352 in 2022, overall violent crime rates tended to decrease, particularly in recent years. However, this correlation is not strong enough to suggest causation.

Applying predictive models based on recent trends, it's projected that violent crime in Caldwell will continue to decrease over the next five years. By 2029, the total number of violent crimes could potentially drop to 1-2 incidents per year, assuming current socio-economic conditions and law enforcement strategies remain consistent.

In summary, Caldwell has shown a generally positive trend in reducing violent crime over the past decade, particularly in recent years. While sporadic incidents of serious crimes like murder and rape have occurred, their frequency has diminished. The most significant improvement has been in aggravated assaults, which have seen a substantial reduction. These trends, if maintained, suggest that Caldwell is moving towards becoming an increasingly safer community for its residents.
