In 2015, another single case was reported, accounting for 0.01% of the state's total. In 2016, there were no reported cases.

Robbery incidents were consistently low in Johnson City. From 2010 to 2016, there were no reported robbery cases. This resulted in a robbery rate of 0 per 1,000 people throughout the period, and the city contributed 0% to the state's total robberies.

Aggravated assault showed some variation over the years. There were no reported cases from 2010 to 2012. In 2013, there were 2 cases, followed by none in 2014. The number increased to 2 in 2015 and then decreased to 1 in 2016. The rate per 1,000 people for aggravated assault peaked in 2013 at approximately 0.64, dropped to 0 in 2014, rose to about 0.63 in 2015, and then decreased to roughly 0.29 in 2016.

When examining correlations between violent crime trends and other factors, there appears to be a weak relationship between population growth and the number of violent crimes. As the population increased, there was a slight tendency for violent crimes to occur more frequently, but this correlation is not strong or consistent enough to draw definitive conclusions.

Applying predictive models to forecast violent crime trends is challenging due to the limited and inconsistent data available. However, if we assume the patterns observed from 2010 to 2016 continue, we might expect the number of violent crimes to remain low, potentially fluctuating between 0 and 3 incidents per year through 2029. This prediction should be treated with caution due to the small sample size and variability in the historical data.

In summary, Johnson City has maintained relatively low levels of violent crime from 2010 to 2016, despite a growing population. The absence of murders and robberies, coupled with sporadic occurrences of rape and aggravated assault, suggests that the city has generally been a safe community during this period. However, the fluctuations in crime rates and the small number of total incidents make it difficult to identify clear trends or make confident predictions about future crime patterns in this small Texas city.
