The number of permits issued for Florida is from November 30, 2013. 1,045,551 Floridians have concealed handgun permits, that is almost 7 percent of Florida's adult population. Santa Rosa is the 30th largest of Florida's 67 counties. It has 17.7% of adults with permits. That makes committing a violent crime in Santa Rosa a lot more dangerous.
While I don't put much weight on purely cross-sectional data, Santa Rosa may be somewhat more populous than the median country, but it has the third lowest violent crime rate (157.7 per 100,000). That is much lower than the rate for the rest of the state. The average rate across counties was 418.3 and the median was 363.8. Indeed, its violent crime rate was very similar to the rates in the two less populous counties that that had lower violent crime rates.
WUFT has also done a study relating permit issuing rate and Stand Your Ground cases, but they can't find a correlation between the two.
