Enter the number of cases and the population size into the calculator to determine the rate per 100,000 population. This calculator helps to standardize the measurement of events across different population sizes.

Rate per 100,000 Population Formula

The following formula is used to calculate the rate per 100,000 population.

Rate per 100,000 = (Number of Cases / Population Size) * 100,000

Variables:

  • Number of Cases is the count of events or occurrences (e.g., diseases, crimes).
  • Population Size is the total number of individuals within the demographic of interest.

To calculate the rate per 100,000 population, divide the number of cases by the population size and then multiply by 100,000 to standardize the rate.

What is Rate per 100,000 Population?

Rate per 100,000 population is a measure used in epidemiology and public health to compare the occurrence of events, such as diseases or crimes, across different population sizes. It allows for a standardized comparison by scaling the rate to a population of 100,000, which helps to understand the relative magnitude of the event in different populations.

How to Calculate Rate per 100,000 Population?

The following steps outline how to calculate the rate per 100,000 population.


  1. First, determine the number of cases.
  2. Next, determine the population size.
  3. Use the formula: Rate per 100,000 = (Number of Cases / Population Size) * 100,000.
  4. Finally, calculate the rate per 100,000 population.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
