Robbery trends in the city show some variability. The highest number of robberies occurred in 2010 with 2 incidents, followed by single incidents in 2011, 2017, 2018, and 2019. In terms of population-adjusted rates, this translates to approximately 1.17 robberies per 1,000 residents in 2010, decreasing to about 0.57 per 1,000 in 2019. The city's contribution to the state's total robbery cases ranged from 0% in years with no incidents to 0.01% in years with reported cases. This low and decreasing trend in robberies, despite population growth, suggests improving safety conditions.

Aggravated assault in Hillsboro Beach has shown a sporadic pattern. The highest number of incidents was 3 in 2011, with single incidents reported in 2010, 2015, 2018, 2019, and 2020. When adjusted for population, the rate peaked at about 1.75 assaults per 1,000 residents in 2011, dropping to approximately 0.53 per 1,000 in 2020. The city's contribution to the state's total aggravated assaults remained minimal, ranging from 0% to 0.01%. This overall low occurrence of aggravated assaults, especially in recent years, indicates a generally safe environment.

Examining correlations, there appears to be a weak inverse relationship between violent crime rates and population density. As the population density increased from 4,664 per square mile in 2010 to 6,084 in 2022, the overall violent crime rate showed a general downward trend. Additionally, there seems to be a slight correlation between median rent increases and decreases in violent crime. The median rent rose from $1,326 in 2013 to $2,740 in 2022, coinciding with generally lower crime rates in later years.

Applying predictive models to forecast violent crime trends for the next five years (up to 2029), based on the historical data and current trends, it's projected that Hillsboro Beach will likely continue to experience very low violent crime rates. The model suggests that the city may see between 0 to 2 violent crimes annually, with a possible slight increase in robberies or aggravated assaults as the population continues to grow. However, the rates per 1,000 residents are expected to remain well below national averages.

In summary, Hillsboro Beach has demonstrated a remarkably low and generally decreasing trend in violent crimes from 2010 to 2022, despite significant population growth. The absence of murders and rapes, combined with infrequent robberies and aggravated assaults, paints a picture of a safe community. These trends, when considered alongside increasing population density and rising median rents, suggest that Hillsboro Beach has managed to maintain and even improve its safety profile while experiencing economic growth and development.
