Overall crime rate is calculated by dividing the total number of reported crimes of any kind by the total population, then multiplying the result by 100,000 (because crime rate is typically reported as X number of crimes per 100,000 people). Crime rates vary greatly from country to country and are influenced by many factors. For example, high poverty levels and unemployment tend to inflate a country's crime rate. Conversely, strict police enforcement and severe sentences tend to reduce crime rates. There is also a strong correlation between age and crime, with most crimes, especially violent crimes, being committed by those ages 20-30 years old.
The overall crime rate in the United States is 47.70. The violent crime rate in the United States has decreased sharply over the past 25 years. Crimes rates vary significantly between the states, with states with such as Alaska, New Mexico, and Tennessee experiencing much higher crime rates than states such as Maine, New Hampshire, and Vermont. Some of the world's lowest crime rates are seen in Switzerland, Denmark, Norway, Japan, and New Zealand. Each of these countries has very effective law enforcement, and Denmark, Norway, and Japan have some of the most restrictive gun laws in the world.
