Difference Between Morbidity and Mortality with Examples

Difference Between Morbidity And Mortality is that morbidity refers to having a disease, illness, or medical condition. Mortality is the total number of deaths in a given population.

Krati Saraswat10 Jun, 2025

Difference Between Morbidity And Mortality: Morbidity and mortality, while related, have different meanings. Morbidity refers to an individual's illness or disease, whereas mortality refers to being on the path of death. These terms can apply to individuals or populations. Morbidity rates, for example, measure the disease occurrence rate in a specific population or geographic area over time, whereas mortality counts the number of deaths caused by a specific illness or condition.

An illness's impact is measured by its mortality rate, commonly expressed as the number of deaths per population. Morbidity and mortality are related because variations in a disease can affect the likelihood that a person will pass away from it. The article provided below details about the difference between morbidity and mortality.

Difference Between Morbidity And Mortality Overview

Mortality, or the death rate in a given population, is an important metric in public health assessment. It provides important information about the effectiveness of healthcare systems, disease burden, and overall population health status. The analysis of mortality data enables policymakers and healthcare practitioners to identify priority intervention areas, allocate resources efficiently, and implement targeted strategies to reduce preventable deaths. By thoroughly understanding mortality patterns, stakeholders can create evidence-based policies and interventions that improve health outcomes and lower premature mortality rates. Morbidity measures the number of cases of illness, injury, and disease in a population, indicating an individual's or community's health and quality of life. Unlike mortality, which only considers fatal outcomes, morbidity includes both non-fatal and fatal consequences, providing a more comprehensive view of health issues. Morbidity indicators such as incidence, prevalence, and disability-adjusted life years (DALYs) can help healthcare professionals identify emerging health trends, assess healthcare needs, and tailor interventions to specific health concerns. Furthermore, understanding morbidity patterns helps to develop targeted health promotion initiatives, preventive strategies, and healthcare delivery models that improve health outcomes and overall well-being. The article below details the difference between morbidity and mortality in tabular form.

Difference Between Morbidity And Mortality

Morbidity and mortality are key concepts in healthcare for assessing the health of individuals and populations. Morbidity refers to illness, disease, or injury frequency, whereas mortality refers to death. Morbidity includes fatal and non-fatal events, whereas mortality only refers to fatal outcomes. The methods and data used to calculate morbidity and mortality vary greatly. Mortality can have significant societal impacts, affecting families and communities, while morbidity can influence an individual's quality of life and healthcare needs. The table below shows the difference between morbidity and mortality.

Difference Between Morbidity And Mortality
Aspect	Morbidity	Mortality
Definition	Morbidity refers to the state of illness or poor health within a population.	Mortality is the term used to describe the number of deaths that occur within a population.
Demographic reference	Morbidity indicates the occurrence of health problems or diseases within a population.	Mortality refers to the incidence or number of deaths within a population.
Database / Reports	Common sources for morbidity data include World Health Statistics, MMWR, EMDB, and NHMD.	The Human Mortality Database is a key resource for mortality data.
Units of measurement	Morbidity scores or predicted morbidity are assigned to ill patients using SAPS II and III, APACHE II, Glasgow Coma scale, PIM2, and SOFA.	Mortality rates are typically expressed as the number of deaths per 1000 individuals per year.
Types of data	Morbidity data is collected based on disease type, gender, age, and geographic area.	The mortality rate can be categorized into various metrics such as crude death rate, perinatal mortality rate, maternal mortality rate, infant mortality rate, child mortality rate, standardized mortality rate, and age-specific mortality rate.

Morbidity

Morbidity refers to the state of being sick or in poor health. It refers to the occurrence or prevalence of illnesses, injuries, or disabilities within a population. Morbidity is caused by various factors, including genetic predisposition, environmental conditions, lifestyle choices, and infectious diseases, which significantly impact healthcare utilization and overall quality of life for individuals, families, and communities. Morbidity can be classified based on the type of disease or injury, its severity, duration, and impact on affected individuals. Acute morbidity refers to short-term illnesses or injuries that are typically self-limiting and resolve either spontaneously or with medical intervention. Chronic morbidity, on the other hand, refers to long-term conditions that can be managed but not cured, and that have a significant impact on those affected's physical, psychological, and social well-being. Morbidity measurement and monitoring are essential for effective healthcare planning, resource allocation, and disease prevention efforts.

Mortality

Mortality refers to death and is often utilized in research to quantify the number of deaths resulting from a particular event or ailment within a defined timeframe. Insurers and public health experts utilize these metrics to evaluate the impact of diseases on healthcare expenses or to determine the optimal allocation of healthcare resources. Mortality rates signify deaths within a specific population during a specified period. In national surveys, this is typically expressed as the number of cases per 100,000 individuals. (In smaller studies, mortality rates might be denoted as deaths per 1,000 or 10,000 individuals.) For example, in the United States, the male lung cancer mortality rate is approximately 40 per 100,000 people. Excess mortality occurs when deaths exceed expected levels. COVID-19 caused 50% more deaths than expected in 2020. The primary causes of death in the United States are several common diseases or occurrences, which account for approximately 75% of all deaths. Heart disease, cancer, chronic lower respiratory diseases like COPD and asthma, stroke, Alzheimer's disease, kidney disease, diabetes, and suicide are among the causes.

Difference Between Morbidity And Mortality FAQs

What is an example of morbidity?

Morbidity, also known as illness, refers to various concurrent health conditions that people may experience. These conditions, known as co-morbidities, range from Alzheimer's disease and cancer to traumatic brain injuries.

What is the measure of morbidity?

Morbidity typically denotes the presence of disease within a population. Accordingly, a morbidity rate serves as a gauge of the prevalence of that disease. This rate can be articulated as a prevalence rate, indicating the total number of cases within the population at a specific time, or as an incidence rate, reflecting the number of new cases within a given timeframe.

Is obesity a morbidity?

Obesity is characterized by an excess accumulation of body fat, which contributes to heightened morbidity and mortality rates.

How to calculate BMI?

Body Mass Index (BMI) provides a straightforward assessment of an individual's weight relative to height. The formula for BMI is BMI = weight (kg) / height (m^2). A BMI of 25.0 or higher indicates overweight status, while a healthy BMI falls within the range of 18.5 to 24.9. This calculation applies to most adults aged 18 to 65 years.
