The crime rate in an area is a measure of the number of crimes committed per capita for a given area or population during a given period of time, usually per year. It is usually represented in crime incidents or violations per 100,000 people.
Crime rates of cities vary drastically based on the city and its location. Cities in densely populated areas often have higher crime rates than rural or suburban settings, sometimes called crime indices.
According to Nambio, the crime index is an estimate of the overall level of crime in a particular city or country, and the data platform has its own index.
Numbeo’s index is based on surveys of visitors to its website. The questions in these surveys are similar to many types of scientific and government surveys. Each entry in the survey is saved as a number in the range [-2, +2]Also -2 means strongly negative and +2 means strongly positive.
Numbeo filters the survey to eliminate potential spam, such as people entering large amounts of data that differ from the average value.
Crime levels below 20, crime levels between 20 and 40 are low, crime levels between 40 and 60 are moderate, crime levels between 60 and 80 and finally crime levels above 80 are very high.
In Nambio’s Global Crime Index list, 17 African cities are featured and the following 10 countries have the lowest crime index.
