Homicide statistics vary from jurisdiction to jurisdiction both within the United States and internationally. The most recent year for which crime statistics are generally available is 2004. International homicide statistics which examine the international rate of homicide by world region are available.
Crime statistics are available for the United States and are divided in two ways. Crime statistics and homicide statistics are available for states which demonstrate the rates on a State by State basis for 2004. The homicide statistics and crime statistics have also been published in the Federal Bureau of Investigation Uniform Crime Reports which show the crime and homicide rates for the twenty largest cities in the United States in 2007.
Homicide statistics compiled by the Geneva Declaration on Armed Violence and Development show that an estimated 490,000 international homicides were committed in 2004. International homicide statistics for 2007 reveal that Southern Africa has the highest homicide rates in the world.
In Southern Africa, there was a homicide rate of 37.3 homicides for every 100,000 people in the region. This was well above the estimated global rate of 7.6 international homicides per 100,000 individuals.
Western and Central Europe have the lowest reported intentional homicide statistics in the world, with only 1.5 homicides for every 100,000 people. Africa as a whole, Central and Southern America, the Caribbean, and Eastern Europe all fall above the global rate. Homicide statistics reveal that North America, Asia, the Near and Middle East, Transcaucasia, Oceania, and South Eastern, Western, and Central Europe all have homicide rates below the international rate.
Crime statistics are available for the twenty largest cities in the United States from 2007. Homicide statistics for these cities only include homicides which occurred within the jurisdiction of the particular city's police department. Homicide statistics report that Detroit, Michigan had the highest homicide rate with 46 murders or non-negligent manslaughter crimes for every 100,000 people in a population of 860,971.
Crime statistics also reveal that Detroit was the city with the highest violent crime rate with 2,289 incidents of violent crime for every 100,000 people. Homicide statistics show that El Paso, Texas, the twentieth largest city in the country, had the lowest rate with only 3 criminal murders happening for every 100,000 people, out of a population of 616,029.
Homicide statistics are also available by State. Three states have a homicide rate of only 1.4 homicides per 100,000 people. These states are Maine, New Hampshire, and North Dakota. Louisiana has the highest rate in the country when evaluated on a per capita basis for more than twenty years. In 2007 there were 12.7 homicides for every 100,000 people in the State. The national homicide rate is 5.5 homicides per every 100,000 people.
Crime statistics are also available on a State by State basis. The national violent crime rate is 465.5 violent crimes per every 100,000 people. Violent crime statistics show that the highest incidence of violent crime is in the District of Columbia, which has 1,371.2 violent crimes per 100,000 people. This sample size is not very conclusive, however, because the population of Washington, D.C. is less than 535,000 people. Violent crime statistics reveal that New Mexico has the highest rate of violent crime, with 687.3 violent crimes being committed per every 100,000 residents.
The majority of homicide victims know their killers beforehand. Homicide statistics from 2001 suggest that 45 percent of all homicides involved individuals in an intimate relationship with each other. Ten percent of all homicides involved the killing of a child by a parent. One in four homicides involved incidents of one friend killing another friend. Despite greater media attention paid to random victimization, there were no relationships between the murderers and their victims in less than ten percent of all homicides.
