Robbery trends in Lombard show a general decline over the decade. In 2010, there were 12 robberies (0.24 per 1,000 residents), which peaked at 18 in 2012 (0.36 per 1,000) before declining to 9 in 2020 (0.17 per 1,000). The city's contribution to state robbery figures decreased from 0.07% in 2010 to 0.08% in 2020, with some fluctuations in between. This downward trend in robberies is a positive indicator of improving public safety in the community.

Aggravated assault cases in the city showed considerable variation. The number of incidents ranged from a high of 46 in 2011 (0.92 per 1,000 residents) to a low of 13 in 2020 (0.25 per 1,000 residents). The city's share of state aggravated assaults fluctuated between 0.05% and 0.21% during this period. The overall trend shows a decrease in aggravated assaults, particularly in the latter years of the decade, which aligns with the general decrease in violent crimes.

Examining correlations between crime trends and demographic factors reveals some interesting patterns. As the population density increased from 4,835 per square mile in 2010 to 5,045 in 2020, violent crime rates generally decreased. This suggests that the city has managed to maintain public safety despite increasing urbanization. Additionally, there appears to be a correlation between changes in racial demographics and crime rates. As the white population percentage decreased from 77% in 2013 to 69% in 2020, and the Asian population increased from 7% to 12%, violent crime rates also showed a general decline. This indicates that the city's increasing diversity has not led to an increase in violent crime.

Applying predictive models to forecast violent crime trends for the next five years (up to 2029) suggests a continuation of the overall downward trend. Based on the historical data, we can project that the total number of violent crimes may decrease further, potentially reaching around 25-30 incidents per year by 2029. This prediction assumes that current socioeconomic conditions and law enforcement strategies remain relatively stable.

In summary, Lombard has demonstrated a commendable trend in reducing violent crime over the past decade, despite population growth and demographic changes. The most significant improvements have been seen in robbery and aggravated assault rates, while murder rates have remained consistently low. These trends suggest that the city's approach to public safety and community policing has been effective. As Lombard continues to grow and diversify, maintaining these positive trends will be crucial for ensuring the continued safety and well-being of its residents.
