How to Use the Calculator
- Select Mortality Rate Type: Choose the specific type of mortality rate you want to calculate (e.g., infant, maternal, or Proportionate).
- Enter the following:
- Deaths due to particular causes: The number of deaths from a specific cause or overall deaths.
- Total population size: The size of the population during the specified period.
- Calculate: Press the calculate button to obtain the mortality rate, expressed as the number of deaths per the selected unit of population.
What’s a Healthy or Unhealthy Range?
The definition of a healthy or unhealthy mortality rate depends on the context and the population being studied. Here are some general guidelines:
- Infant Mortality Rate: Developed nations often have rates below 5 per 1,000 live births, whereas rates above 50 per 1,000 indicate significant healthcare challenges.
- Maternal Mortality Rate: Rates below 10 per 100,000 live births are considered low, higher rates suggest healthcare disparities.
- Proportionate Death Rate: A higher proportionate death rate for a specific cause may indicate significant health challenges or underlying issues in healthcare access and disease prevention.
What Does Mortality Rate Mean?
The simplest mortality rate definition is the measure of the frequency of death in a specific population measured over a defined time period. It's usually expressed per 10ⁿ people. For example, a mortality rate of 8.91 per 10,000 (n = 4) means that approximately 8.91 people out of every 10,000 died over the specified time.
Difference Between Morbidity and Mortality
- Morbidity: Refers to the prevalence of diseases, not necessarily fatal.
- Mortality: Refers specifically to death. A high morbidity rate may lead to an increased mortality rate. For example, controlling disease spread can reduce deaths, emphasizing the importance of preventive measures like vaccination and hygiene.
How to Calculate Mortality Rate
- Identify the number of deaths and the population size.
- Apply the formula:
The crude death rate formula can be expressed as:
death rate = deaths / population × 10ⁿ
where,
deaths — Deaths measured within the specified time interval for a certain population
n — The exponent gives you the answer per every 10n people. So, for example, if you choose n = 3, you obtain the death rate for every 1000 people.
The critical thing to note is that this mortality rate formula also works for specific and combined cases. The only difference is that you use numbers for your chosen group instead of the whole population.
For an infant mortality rate calculation, we use the formula:
Infant mortality rate = deaths among children / live births × 10ⁿ,
If you are wondering how to calculate the maternal mortality ratio, here is your answer:
maternal mortality rate = deaths during pregnancy / live births × 10ⁿ,
where both variables are measured over the same time interval, and deaths during pregnancy include those that happened within 42 days of its termination.
High Mortality Rate: What Does It Mean?
High mortality rates often signal significant public health challenges, such as:
- Disease outbreaks (e.g., pandemics, epidemics).
- Limited access to healthcare.
- Socioeconomic issues, such as poverty or war.
Importance in Epidemiology
Mortality rate calculations provide vital insights into:
- Population health risks.
- Effectiveness of healthcare systems.
- Long-term demographic trends.
Use this calculator as a step towards understanding and addressing critical health challenges in any population.
