Overall Global Leading Cause of Death

  • Ischemic heart disease (coronary artery disease) – Still the #1 cause of death worldwide.
  • Followed by: Stroke, chronic obstructive pulmonary disease (COPD), lower respiratory infections, and cancer (e.g., lung, liver, colorectal).

Breakdown by Category

By Age

Age GroupLeading Cause(s) of Death
Infants (<1)Neonatal conditions, birth complications, infections
Children (1–14)Accidents (injuries), infections (low-income countries), cancers (e.g., leukemia)
Youth (15–24)Road injuries, suicide, homicide (varies by country)
Adults (25–44)Injuries (road, drug overdose), suicide, HIV/AIDS (in some countries), heart disease
Middle Age (45–64)Heart disease, cancer (esp. lung, colorectal, breast), liver disease
Older Adults (65+)Heart disease, stroke, cancer, Alzheimer’s disease

By Gender/Sex

GroupLeading Cause of Death
Cisgender MenHeart disease, cancer (lung, liver), accidents
Cisgender WomenHeart disease, cancer (breast, lung), stroke
Transgender IndividualsElevated risk from violence, suicide, and HIV/AIDS (especially trans women of color); limited large-scale data
Non-binaryInsufficient population-specific data, but risks often parallel those of trans populations or assigned sex at birth

By Race/Ethnicity (Example: United States)

GroupTop CausesUnique Issues
White (non-Hispanic)Heart disease, cancer, drug overdose
Black or African AmericanHeart disease, cancer, higher stroke risk
Hispanic/LatinoHeart disease, cancer, diabetes
Native AmericanAccidents, liver disease, diabetes, suicide
Asian AmericanCancer (leading cause), stroke, heart disease

Note: Disparities arise from systemic inequalities, access to care, and social determinants of health.


By Sexuality (LGBTQ+)

  • Limited global data, but in many regions:
    • Higher risk of suicide, mental health disorders, substance abuse, HIV/AIDS (especially among MSM and trans women).
    • Discrimination and healthcare avoidance contribute to worsened outcomes.
  • Common causes of death still include heart disease and cancer, with higher rates of premature death linked to stigma and healthcare disparities.

By Geographic Region

RegionLeading Cause(s)
High-Income CountriesHeart disease, cancer, Alzheimer’s, stroke
Low- and Middle-Income CountriesInfectious diseases (TB, HIV), maternal mortality, stroke, heart disease
AfricaHIV/AIDS, malaria, lower respiratory infections
AsiaStroke, heart disease, chronic lung disease
North AmericaHeart disease, cancer, drug overdose (opioid crisis)
EuropeHeart disease, stroke, cancer
Latin AmericaViolence (in younger adults), heart disease, diabetes

By Profession

  • Agricultural/farm workers: High injury rates, pesticide exposure, suicide
  • Construction workers: Falls, injuries, exposure to toxins (e.g., asbestos)
  • Healthcare workers: Infectious disease, burnout, mental health risks
  • Military/first responders: Combat-related injuries, PTSD, suicide
  • Office workers: Sedentary lifestyle risks (heart disease, diabetes)

Occupation-linked deaths often relate to environmental exposures, physical risks, or psychological stressors.


Conclusion:

Across almost all demographics, heart disease remains the leading cause of death, followed by cancer, stroke, and—in certain populations—accidents, suicide, or infectious diseases. However, the underlying causes (social, economic, political) differ significantly based on identity, geography, and profession.

Fact. Truth. Belief. They are related but distinct. Here’s a clear explanation showing how they differ and interact:Fact. Truth. Belief. They are related but distinct. Here’s a clear explanation showing how they differ and interact:


1. Fact

Definition:
A fact is something that is objectively real and can be proven to be true. It exists independently of what anyone thinks or believes.

Example:

  • It is a fact that Australia is in the Southern Hemisphere.

Key Points:

  • Facts don’t change based on opinion.
  • They can be verified with evidence (e.g. scientific data, observation, reliable records).
  • Facts are the foundation upon which truth claims and beliefs can be tested.

2. Truth

Definition:
Truth is a quality of a statement or belief that accurately reflects reality or fact.

Example:

  • “Australia is in the Southern Hemisphere” is a true statement because it corresponds with the fact.

Key Points:

  • Truth depends on alignment with facts.
  • Truth is often expressed in language or claims (“That’s true”, “That’s not true”).
  • Something can be true even if no one believes it (e.g. the Earth orbited the Sun even when most people thought otherwise).

3. Belief

Definition:
A belief is something a person thinks or accepts as true, whether or not it actually is.

Example:

  • Someone might believe that kangaroos can be kept as pets in all Australian states — but that belief isn’t necessarily true or factual.

Key Points:

  • Beliefs are subjective — they vary between individuals and cultures.
  • A belief can be true or false, depending on whether it aligns with facts.
  • People often act based on their beliefs, regardless of whether they are accurate.

How They Interact

  • A belief can be true or false:
    → If your belief aligns with fact, it’s true.
    → If not, it’s false — even if sincerely held.
  • Truth depends on fact:
    → A statement is true if it correctly describes a fact.
  • Facts stand alone:
    → They are not changed by belief or opinion.

The stages of change modelThe stages of change model

‘The stages of change model’ was developed by Prochaska and DiClemente. Heard of them? It informs the development of brief and ongoing intervention strategies by providing a framework for what interventions/strategies are useful for particular individuals. Practitioners need an understanding of which ‘stage of change’ a person is in so that the most appropriate strategy for the individual client is selected.

There are five common stages within the Stages of Change model and a 6th known as “relapse”:

1. In the precontemplation stage, the person is either unaware of a problem that needs to be addressed OR aware of it but unwilling to change the problematic behaviour [or a behaviour they want to change. It does not always have to be labelled as “problematic”].

2. This is followed by a contemplation stage, characterized by ambivalence regarding the problem behaviour and in which the advantages and disadvantages of the behaviour, and of changing it, are evaluated, leading in many cases to decision-making.

3. In the preparation stage, a resolution to change is made, accompanied by a commitment to a plan of action. It is not uncommon for an individual to return to the contemplation stage or stay in the preparation stage for a while, for many reasons.

4. This plan is executed in the action stage, in which the individual engages in activities designed to bring change about and in coping with difficulties that arise.

5. If successful action is sustained, the person moves to the maintenance stage, in which an effort is made to consolidate the changes that have been made. Once these changes have been integrated into the lifestyle, the individual exits from the stages of change.

6. Relapse, however, is common, and it may take several journeys around the cycle of change, known as “recycling”, before change becomes permanent i.e., a lifestyle change; a sustainable change.
