Robbery trends show a slight overall decrease from 2010 to 2022. In 2010, there were 7 robberies reported, which increased to 14 in 2011 but then gradually decreased to 11 in 2016. By 2022, the number had returned to 14. The robbery rate per 1,000 residents has remained relatively stable, ranging from 0.10 to 0.21. The city's percentage of state robberies has increased slightly from 0.04% in 2010 to 0.13% in 2022, indicating a marginal rise in the city's contribution to state robbery statistics.

Aggravated assault incidents have shown significant fluctuations. In 2010, there were 40 reported cases, which increased to 49 in 2011. The numbers then decreased to 28 in 2016 before rising again to 46 in 2022. The aggravated assault rate per 1,000 residents has ranged from 0.40 to 0.72 over the period. The city's percentage of state aggravated assaults has varied from 0.06% to 0.36%, with the highest percentage occurring in 2022. This suggests that aggravated assault has become a more significant issue in recent years relative to state trends.

When examining correlations, there appears to be a moderate relationship between population density and violent crime rates. As the population density increased from 4,756 per square mile in 2010 to 4,948 in 2022, violent crime rates showed some fluctuations but generally remained within a similar range. Additionally, there seems to be a weak correlation between the changing racial demographics and crime rates. The percentage of white residents decreased from 64% in 2013 to 57% in 2022, while the Hispanic population increased from 19% to 24% during the same period. However, these demographic shifts do not show a strong direct correlation with violent crime trends.

Applying predictive models based on the available data, it is estimated that by 2029 (five years from now), Des Plaines may see a slight increase in violent crimes, potentially reaching around 75-80 incidents per year. This prediction assumes that current trends and factors influencing crime rates remain relatively stable.

In summary, Des Plaines has experienced a complex pattern of violent crime over the past decade. While overall violent crime has decreased slightly, individual categories such as aggravated assault have shown recent increases. The city's contribution to state crime statistics remains relatively small but has grown in some categories. As Des Plaines continues to evolve demographically and economically, ongoing monitoring and targeted prevention strategies will be crucial in maintaining public safety and addressing emerging crime trends.
