Robbery trends showed a more positive development. The number of robberies decreased from 96 in 2010 to 80 in 2020, a 16.7% reduction. The robbery rate per 1,000 residents fell from 1.123 in 2010 to 0.939 in 2020. The city's share of state robberies remained relatively stable, fluctuating between 0.15% and 0.27% over the decade, suggesting that the city's robbery trends generally aligned with state-wide patterns.

Aggravated assaults experienced a significant decline. In 2010, there were 225 reported cases, which decreased to 131 in 2020, a 41.8% reduction. The rate per 1,000 residents dropped from 2.633 in 2010 to 1.538 in 2020. The city's percentage of state aggravated assaults decreased from 0.3% in 2010 to 0.15% in 2020, indicating that the city made more progress in reducing aggravated assaults compared to the state average.

A strong correlation was observed between violent crime rates and median rent. As median rent increased from $1,174 in 2013 to $1,587 in 2020, violent crime rates generally decreased. This suggests that improving economic conditions may have contributed to reduced violent crime. Additionally, there appears to be a correlation between the Hispanic population percentage and violent crime rates. As the Hispanic population increased from 66% in 2013 to 68% in 2020, violent crime rates showed an overall downward trend, indicating that demographic shifts may have influenced crime patterns.

Applying predictive models to forecast violent crime trends for the next five years (up to 2029), we anticipate a continued overall decrease in violent crime rates. Based on historical trends, murders may stabilize around 3-4 per year, rape incidents could potentially decrease to around 15-20 annually, robberies might further reduce to approximately 70-75 cases per year, and aggravated assaults could potentially decline to around 100-110 incidents annually.

In summary, Whittier has shown mixed trends in violent crime over the past decade, with significant reductions in aggravated assaults and robberies, but concerning increases in murders and rapes. The city's overall violent crime rate has decreased, outpacing population growth. Economic improvements, as indicated by rising median rents, appear to correlate with reduced violent crime rates. These trends, combined with demographic shifts, suggest a complex interplay of factors influencing crime patterns in Whittier, pointing towards a generally improving safety situation with specific areas requiring continued attention and intervention.
