Robbery statistics for Ravenna show no reported incidents from 2011 to 2022. The robbery rate per 1,000 people and the percentage of state robberies consistently remained at 0% throughout this period. This absence of robberies contributes to the overall low violent crime profile of the city.

Aggravated assault figures mirror the trends seen in other violent crime categories, with no reported cases from 2011 to 2022. The rate of aggravated assaults per 1,000 people and the percentage of state aggravated assaults stayed at 0% for the entire period. This consistent lack of aggravated assaults further reinforces the low violent crime environment in the city.

When examining correlations between violent crime trends and other factors, the data does not support strong relationships due to the extremely low incidence of violent crime. The single reported violent crime in 2017 coincided with a population of 588, which was higher than most years in the dataset, but this isolated incident is insufficient to establish a meaningful correlation with population density or other factors.

Applying predictive models to forecast violent crime trends for the next five years (up to 2029) is challenging due to the extremely low base rate of violent crime. Given the historical data showing only one incident in over a decade, it's reasonable to predict that Ravenna will likely continue to experience very low rates of violent crime, potentially maintaining zero incidents in most years, with the possibility of isolated occurrences similar to the 2017 event.

In summary, Ravenna demonstrates an exceptionally low violent crime profile from 2011 to 2022, with only one reported incident throughout the entire period. This pattern suggests a consistently safe environment for residents, despite minor fluctuations in population. The city's ability to maintain such low crime rates over an extended period is noteworthy and likely contributes positively to the quality of life for its inhabitants.
