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.
The formula to calculate the rate per 100,000 population is:
\[ \text{Rate per 100,000} = \left( \frac{\text{Number of Cases}}{\text{Population Size}} \right) \times 100,000 \]
Where:
Let's say there are 500 cases in a population of 1,000,000. Using the formula:
\[ \text{Rate per 100,000} = \left( \frac{500}{1,000,000} \right) \times 100,000 \]
We get:
\[ \text{Rate per 100,000} = 50 \]
So, the rate per 100,000 population is 50.
