Robbery trends in the community show a consistently low rate. From 2010 to 2022, there were no reported robberies. This translates to a robbery rate of 0 per 1,000 people throughout the entire period, regardless of population changes. The city's contribution to the state's robbery statistics has remained at 0%, indicating that it has not been a factor in the state's overall robbery figures.

Aggravated assault has shown the most variation among violent crimes in the city. In 2010, there were 8 reported cases, which then dropped to zero for several years. In 2017, 2 cases were reported, followed by another period of no incidents until 2022, when 1 case was recorded. The rate per 1,000 people has fluctuated accordingly: 3.34 in 2010, 0.97 in 2017, and 0.52 in 2022. The city's contribution to state aggravated assault statistics has varied from 0.07% in 2010 to 0.02% in 2017, and 0.01% in 2022, showing a decreasing trend in the city's impact on state figures.

Examining correlations, there appears to be a moderate inverse relationship between population density and violent crime rates. As population density decreased from 736 per square mile in 2010 to 593 in 2022, violent crime incidents generally trended downward, with some fluctuations. Additionally, there seems to be a weak positive correlation between median rent and crime rates. As median rent increased from $493 in 2013 to $791 in 2022, violent crime incidents showed a slight uptick in later years, though the relationship is not strong enough to draw definitive conclusions.

Applying predictive models to forecast violent crime trends for the next five years (up to 2029), based on the current data and assuming continuation of recent trends, we might expect the following: Murder rates are likely to remain at zero, given the consistent absence of such incidents. Rape incidents may occur sporadically, potentially averaging one case every 3-4 years. Robbery rates are expected to stay at zero, barring any significant changes in local conditions. Aggravated assaults may continue to occur at a low rate, potentially averaging 1-2 cases per year.

In summary, Enigma has demonstrated a generally positive trend in violent crime reduction over the past decade. The most significant changes have been in aggravated assaults, which have shown a marked decrease both in number and as a percentage of state totals. The city's ability to maintain zero murders and robberies throughout the period is noteworthy, especially given the population fluctuations. While sporadic incidents of rape and assault still occur, their frequency and rate per capita have generally decreased. These trends, coupled with the declining population, suggest that the city may continue to experience low levels of violent crime in the near future, barring any significant societal or economic changes.
