Aggravated assault was the most prevalent form of violent crime in the city. In 2010, there were 3 incidents, representing 0.03% of the state's aggravated assaults. This number dropped to 0 in 2011, rose back to 3 in 2012 (0.03% of state), then decreased to 2 in 2013 (0.02% of state), further to 1 in 2014 (0.01% of state), and finally to 0 in 2015. The rate per 1,000 people for aggravated assault started at approximately 2.17 in 2010, peaked at about 2.01 in 2012, and then steadily declined to 0 by 2015.

Examining correlations, there appears to be a weak inverse relationship between population growth and violent crime rates. As the population increased from 1,382 in 2010 to 1,546 in 2015, the total number of violent crimes decreased from 3 to 0. However, the small number of incidents makes it difficult to establish a strong statistical correlation.

Applying predictive models based on the limited data available, it's challenging to make accurate forecasts. However, if the trend of decreasing violent crime continues, we might expect the city to maintain very low levels of violent crime through 2029 (seven years from 2022, presented as five years from now). The population is likely to continue its growth trend, potentially reaching around 2,000 by 2029 if the growth rate remains consistent.

In summary, Poulan demonstrated a positive trend in violent crime reduction from 2010 to 2015, with aggravated assault being the primary concern that showed significant improvement. The absence of murders and the near-absence of robberies, combined with the overall decrease in violent incidents despite population growth, suggest a generally improving safety situation in the city. However, the limited data and small number of incidents make it crucial to interpret these trends cautiously and continue monitoring crime patterns to ensure the maintenance of public safety in this growing community.
