Mortality Rate Formula:
| From: | To: |
The mortality rate is a measure of the number of deaths in a particular population, scaled to the size of that population, per unit of time. It is typically expressed in units of deaths per 1,000 individuals per year.
The calculator uses the mortality rate formula:
Where:
Explanation: The formula calculates the crude death rate, which is the simplest mortality measure representing the number of deaths per 1,000 people in a given population during a specified time period.
Details: Mortality rates are key indicators of population health and are used by epidemiologists, public health officials, and policymakers to assess health status, plan health services, and evaluate health interventions.
Tips: Enter the number of deaths and the total population count. The population must be greater than zero. The calculator will compute the mortality rate per 1,000 population.
Q1: What's the difference between mortality rate and fatality rate?
A: Mortality rate refers to deaths in a general population, while fatality rate refers to deaths among people with a specific condition.
Q2: What is a normal mortality rate?
A: Normal rates vary by country and age group. The global average is about 7.6 deaths per 1,000 people per year.
Q3: What time period does this calculate for?
A: This calculates the crude death rate which is typically annual, but you can use it for any time period as long as deaths and population correspond to the same period.
Q4: Are there more specific mortality rates?
A: Yes, there are age-specific, cause-specific, and other specialized mortality rates that provide more detailed information.
Q5: Why multiply by 1000?
A: Multiplying by 1000 converts the rate to "per 1000 population" which is easier to interpret than a decimal fraction.
