Robbery rates in Laddonia have remained at zero throughout the observed period from 2015 to 2018. This consistent absence of robberies, maintaining a 0% share of the state's total, suggests effective crime prevention or a lack of targets for such crimes in this small community.

Aggravated assault trends show some variation. In 2015 and 2018, no incidents were reported. However, in 2016, there was one case (1.71 per 1,000 people), and in 2017, two cases were reported (3.15 per 1,000 people). These incidents represented 0.01% of the state's total aggravated assaults in both years. The spike in 2017 is notable, but without more long-term data, it's difficult to determine if this represents a trend or an anomaly.

When examining correlations, there appears to be a weak relationship between population density and violent crime rates. As the population density increased from 805 per square mile in 2015 to 873 in 2018, violent crime incidents fluctuated without a clear pattern. The racial distribution remained relatively stable during this period, with the white population consistently comprising 97-98% of the total, showing no strong correlation with crime rates.

Applying predictive models based on the limited data available, it's challenging to forecast with high confidence. However, if current trends continue, we might expect violent crime rates to remain low and sporadic in Laddonia through 2029. The city may experience between 0 to 2 violent crimes annually, with aggravated assault being the most likely type of incident.

In summary, Laddonia demonstrates a pattern of low violent crime rates with occasional incidents. The most significant finding is the consistent absence of murders and robberies, coupled with sporadic occurrences of rape and aggravated assault. These trends, set against the backdrop of a slowly growing population, suggest that Laddonia maintains a relatively safe environment for its residents, with violent crime being an infrequent occurrence rather than a persistent issue.
