Robbery figures in Emma mirror the trends seen in other violent crime categories, with zero incidents reported from 2011 to 2015. The robbery rate per 1,000 people is 0, and the city's share of state robbery statistics remains at 0% for the entire period. This consistency is notable given the population changes during these years.

Aggravated assault data for Emma follows the same pattern as other violent crime categories, with no incidents reported from 2011 to 2015. The rate of aggravated assaults per 1,000 people is 0, and the city's contribution to state aggravated assault statistics is 0% throughout the period. This trend has remained stable despite the declining population.

Given the consistent zero violent crime rate across all categories, there are no meaningful correlations to be drawn between violent crime trends and other demographic factors such as population density, median rent, or race distribution in Emma.

Applying predictive models to forecast violent crime trends for Emma is challenging due to the consistent zero-rate history. Assuming this trend continues, the prediction for violent crime in the city for the next seven years (until 2029, which we'll present as five years from now) would remain at zero across all categories. However, it's important to note that even a single incident in a small population can significantly impact the crime rate, so continued vigilance would be prudent.

In summary, Emma presents a unique case of a small Missouri community that has maintained a zero violent crime rate across all categories from 2011 to 2015, despite experiencing population decline. This consistent safety record is a notable achievement for the city and sets a high standard for community safety. As Emma moves forward, maintaining this exemplary public safety record while addressing its population decline could be key focuses for local policymakers and community leaders.
