Robbery trends in the city show an absence of reported cases throughout the entire period from 2010 to 2022. The robbery rate per 1,000 people and the percentage of state robbery crimes attributed to the city remained at zero consistently. This indicates that robbery is not a significant concern for the community.

Aggravated assault has been the most prevalent form of violent crime in the city. The number of incidents fluctuated over the years, with notable peaks of 15 cases in 2018 and 7 cases in 2019. The aggravated assault rate per 1,000 people was highest in 2018 at 9.15, followed by 4.20 in 2019. The city's contribution to state aggravated assault crimes peaked at 1.19% in 2018 and 0.45% in 2019. These figures suggest that while aggravated assault is more common than other violent crimes, its occurrence is still relatively low and inconsistent.

Examining correlations, there appears to be a weak positive relationship between population growth and the number of aggravated assaults. As the population increased from 1,637 in 2010 to 2,008 in 2022, there was a general upward trend in aggravated assault cases, although with significant year-to-year variations. The racial composition of the city remained predominantly white throughout the period, with the percentage of white residents consistently above 90%, showing no strong correlation with crime trends.

Applying predictive models to forecast violent crime trends for the next five years (up to 2029), based on historical data, we can anticipate: Murder and robbery rates are likely to remain at or near zero, given the consistent absence of these crimes over the past decade. Rape incidents may continue to occur sporadically, potentially averaging less than one case per year. Aggravated assault cases are projected to fluctuate between 2 to 8 incidents annually, with an average of around 4-5 cases per year.

In summary, Manhattan has maintained relatively low violent crime rates despite its population growth. The absence of murders and robberies, coupled with infrequent rape cases, paints a picture of a generally safe community. Aggravated assault remains the primary violent crime concern, but its occurrence is still relatively low compared to larger urban areas. The city's consistent racial composition and steady population growth have not shown strong correlations with violent crime trends, suggesting that other factors may be more influential in determining crime rates in this small Montana community.
