Enter the number of events and the total population into the calculator to determine the rate per 100 individuals. This calculator helps to understand the frequency of an event in a population.

Rate Per 100 Formula

The following formula is used to calculate the rate per 100 individuals in a population.

Rate Per 100 = (Number of Events / Total Population) * 100

Variables:

  • Number of Events is the count of occurrences of a specific event.
  • Total Population is the number of individuals in the group being studied.

To calculate the rate per 100, divide the number of events by the total population and then multiply the result by 100 to get the rate per 100 individuals.

What is Rate Per 100?

Rate per 100 is a way to standardize the frequency of an event in a population, making it easier to compare across different populations or time periods. It is often used in fields such as epidemiology, public health, and statistics to report the occurrence of events, such as the incidence of a disease, in a standardized format.

How to Calculate Rate Per 100?

The following steps outline how to calculate the Rate Per 100.


  1. First, determine the number of events that have occurred.
  2. Next, determine the total population size.
  3. Use the formula: Rate Per 100 = (Number of Events / Total Population) * 100.
  4. Finally, calculate the Rate Per 100 to understand the frequency of the event per 100 individuals in the population.
  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.
