The crime rate of an area is a measure of the number of crimes committed in that area or population during a specific time period, generally per capita per year. Often represented in criminal incidents or offenses per 100,000 people.
City crime rates vary drastically based on city and location. Cities in more densely populated areas often have higher crime rates, sometimes called crime indexes, than rural or suburban areas.
According to Numbeo, the Crime Index is an overall estimate of the crime rate in a given city or country, and the data platform has its own index.
The Numbeo Index is based on a survey of website visitors. The questions for this survey are similar to many similar scientific and government surveys. Each entry in the survey is stored as a number in a range [-2, +2]with -2 meaning very negative and +2 meaning very positive.
Numbeo filters surveys to remove potential spam, as people enter large amounts of data that differ from the median value.
The crime rate is lower than 20, the crime rate between 20 and 40 is low, the crime rate between 40 and 60 is moderate, the crime rate between 60 and 80 is high, and finally the crime rate is higher than 80 is very high. .
In Numbeo’s global crime index list, 17 African cities are shown, and below are the 10 countries with the lowest crime index.
