Enter the number of murders and the population into the calculator to determine the murder rate per 100,000 people.

Murder Rate Formula

The following formula is used to calculate the murder rate:

MR = (M / P) * 100,000

Variables:

  • MR is the murder rate per 100,000 people
  • M is the number of murders
  • P is the population

To calculate the murder rate, divide the number of murders by the population and then multiply by 100,000.

What is a Murder Rate?

The murder rate is a measure used to determine the frequency of murder in a given population size. It is typically expressed as the number of murders per 100,000 inhabitants over a specific time period, usually one year. This rate allows for comparisons between areas of different population sizes and can be used to assess the safety and security of a region.

How to Calculate Murder Rate?

The following steps outline how to calculate the Murder Rate.


  1. First, determine the number of murders (M).
  2. Next, determine the population (P).
  3. Next, gather the formula from above = MR = (M / P) * 100,000.
  4. Finally, calculate the Murder Rate (MR) per 100,000 people.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

number of murders (M) = 50

population (P) = 150,000
