The robbery statistics for the city show a consistent pattern of zero incidents from 2010 to 2022. This translates to a robbery rate of 0 per 1,000 residents and 0% of the state's total robberies for each year data was reported. The absence of robberies suggests a relatively safe environment for residents and businesses in terms of this particular crime category.

Aggravated assault trends in the city have shown some variation over the years. There were no reported cases from 2010 to 2013. In 2017, there was one incident, representing a rate of approximately 1.32 per 1,000 residents based on the population of 756 that year. This single case accounted for 0.07% of the state's total aggravated assaults. In 2019, the number increased to 3 incidents, resulting in a rate of about 4.19 per 1,000 residents, given the population of 716. This spike represented 0.19% of the state's aggravated assaults for that year. However, in 2021 and 2022, the number of aggravated assaults returned to zero.

When examining correlations between violent crime trends and other factors, a potential relationship emerges with population density. The years with reported violent crimes (2014, 2017, and 2019) coincided with periods of relatively higher population density, ranging from 976 to 1,023 people per square mile. However, this correlation is not strong enough to suggest causation, given the low overall crime numbers and the fact that many years with similar population densities saw no violent crimes.

Applying predictive models to forecast violent crime trends for the next five years (up to 2029) is challenging due to the low and inconsistent number of incidents. However, based on the historical data, it's reasonable to project that the city will continue to experience very low violent crime rates, with the possibility of occasional isolated incidents, particularly in the category of aggravated assault. The forecast suggests that murder, rape, and robbery are likely to remain at or near zero, while aggravated assaults may occur sporadically, potentially not exceeding 1-2 cases per year.

In summary, Ennis demonstrates a remarkably low violent crime rate across all categories. The most significant finding is the complete absence of murders and robberies throughout the examined period, coupled with only one reported rape incident in over a decade. Aggravated assaults, while showing some fluctuation, remain infrequent. These discoveries paint a picture of Ennis as a generally safe community with minimal violent crime concerns, despite minor population fluctuations over the years.
