QuickStats: Age-Adjusted Homicide Rates,* by Sex and Type of Locality† — United States, 2007–2009

The figure indicates that during 2007–2009 the homicide rate in the United States was highest in large central metropolitan counties. For males, the age-adjusted homicide rate in large central metropolitan counties was 76% higher than the rate in medium metropolitan counties (14.4 versus 8.2 per 100,000 population) and more than double (122%–129% higher) the rates in other types of localities. In each type of locality, the homicide rate was much higher for males than females.

* Per 100,000 standard population. Deaths from homicide are those coded *U01–*U02, X85–Y09, and Y87.1 in the International Classification of Diseases, 10th Revision.

Counties were classified into urbanization levels based on a classification scheme that considers metropolitan/nonmetropolitan status, population, and other factors.

Among males and females, the homicide rate during 2007–2009 was highest in large central metropolitan counties. For males, the age-adjusted homicide rate in large central metropolitan counties was 76% higher than the rate in medium metropolitan counties (14.4 versus 8.2 per 100,000 population) and more than double (122%–129% higher) the rates in other types of localities. For females, the homicide rates ranged from a high of 2.9 in large central metropolitan counties to 1.9 in large fringe metropolitan counties. In each type of locality, the homicide rate was much higher for males than females. Overall, the homicide rate was 9.1 per 100,000 population for males and 2.5 for females.
