Leading Causes Of Death In The World, & In Different Countries

Becoming aware of leading causes of death can be a good way to make changes today that could contribute to lowering mortality rates in the future.

In this guide, we list the leading causes of death worldwide, and in specific countries.

 

Summary – Leading Causes Of Death

Diseases that affect the heart, along with cancer are some of the most common leading causes of death worldwide

Having said that, causes of death can vary between countries, and especially between developed and developing countries (e.g. non communicable vs infectious diseases)

In countries with access to adequate sanitation, healthcare and nutrition, the risk of falling victim to a leading cause of death can be significantly lowered, and preventative measures can be taken. For example, good nutrition, exercise, keeping a healthy weight, not smoking, drinking in moderation, and a healthy lifestyle might help lower the risk of leading causes of death like heart diseases. Deaths in developed countries tend to be largely preventable or treatable, and tend to be chronic, or slow to progress/develop causes

Some countries have non preventable factors at play, like lack of access to proper resources and healthcare (for prevention and treatment). But, the good news is that access to basic healthcare is increasing worldwide, and other key measurements like child mortality rates are dropping (or trending in the right direction)

In the US specifically, heart disease has been trending down, whilst cancers have been trending up over the last few decades. 

Leading causes of death can change over time as lifestyles, technology, and other social and economic variables change. Pandemics and related causes can also skew data in a given year or multi year period

 

A few other notes worth mentioning are:

Leading causes of death can be expressed in a number of different ways – total deaths, deaths as a % of total deaths, and deaths per 100,000 people are a few main examples

Leading causes of death can differ by age group

Leading causes of death can differ by gender

Leading causes of death can differ by race

Leading causes of death can differ by country or region

Leading causes of deaths can also be calculated by occupation in terms of deaths per 100,000 people in a profession or industry

 

Leading Causes Of Death In The World

According to healthline.com:

In 2015, of the estimated 56.4 million people that died worldwide, 68% were due to slowly progressing diseases

In 2015, the top 4 causes of death were …

Ischemic heart disease, or coronary artery disease (8.8 million, 15.5% of deaths)

Stroke (6.2 million, 11.1% of deaths)

Lower respiratory infections (3.2 million, 5.7% of deaths)

Chronic obstructive pulmonary disease (3.1 million, 5.6% of deaths)

Smoking is a common contributing factor to several of the leading causes of death worldwide

Due to a range of factors, there’s some clear trends of increasing and decreasing death rates of some of the leading causes of death between developed, and developing countries.

Many of the diseases on the list are preventable and treatable

 

According to bbc.com:

In 2016 …

Cardio vascular diseases (which affects the heart and arteries) are responsible for 32.3% of deaths, Cancers 16.3%, and there is a big drop off from there to respiratory diseases at 6.5%, diabetes at 5.8%, and other causes of death

More than 70% of people die from non-communicable, chronic diseases. These are not passed from person to person and typically progress slowly

Worldwide, we can see the child mortality rate has severely dropped since 1950

 

According to ourworldindata:

In 2017 …

Cardiovascular diseases are the leading cause of death globally. The second biggest cause are cancers.

Causes of death vary significantly between countries: non-communicable diseases dominate in rich countries, whereas infectious diseases remain high at lower incomes.

Fewer people die at a young age. Almost half of all people who die are 70 years and older.

Leading risk factors for premature death globally include high blood pressure, smoking, obesity, high blood sugar and environmental risk factors including air pollution.

[There tends to be a big difference in what is actually causing people to die, and what types of deaths receive news and media coverage]

 

Leading Causes Of Death In The United States

According to healthline.com:

Heart disease (635,260) and Cancer (598,038) are responsible for 46 percent of deaths in the US, and are the two most common causes of death

Smoking/the use of tobacco, and being overweight/obese are a few of the common causes to the leading causes of death

Heart disease related deaths have been falling over the last few decades whilst cancer related deaths have been rising

[Data is from the CDC 2017 report]

This wikipedia.org resource also has graphs for the leading causes of death in the United States by age group, and also shows the death rate per 100,000 workers by occupation. Cell tower construction, fishing, logging and aircraft pilots and flight engineers all rate amongst the highest occupational death rates.

What Can Be Learnt From Looking At The Leading Causes Of Death

From looking at leading causes of death, we can:

Gain awareness of the leading causes of death

Find out if there are growing epidemics in healthcare i.e. if one or several leading causes are becoming significant for any reason

Find out what causes of death are increasing in frequency and which ones are trending down

Determine what people (and also what regions and countries) might be at risk of certain leading causes of death. We can also see leading causes of death by age group, by gender, and also death rates per capita by occupation

Gain awareness of the things that are risk factors and contributing factors to a leading cause of death

Identify preventable, partially preventable, and non preventable contributing factors to leading causes of death (and example of a non preventable factor might be lack of access to preventative or quality healthcare) 

Spread awareness about prevention measures and things that can lower risk for a leading cause of death Generally, good nutrition and exercise, avoiding smoking and drinking, and proper hygiene can lower the risk of several leading causes of death in developed countries. Better sanitation, hygiene, nutrition, vaccination and basic healthcare can lower risk in developing countries
