Close behind are the United Kingdom (42.70), Slovakia (38.15), Albania (36.92), and Iceland (35.59). Surprisingly, even technologically advanced nations like the United States (33.26) and Sweden (30.96) appear on the top 10 list—underscoring the fact that this issue transcends borders and income levels.

Why are these numbers so high?

One of the key drivers behind these rising death rates is increased life expectancy. According to global health data, from 1990 to 2019, the incidence of Alzheimer’s disease and other dementias rose by a staggering 147.95%. As people live longer, particularly in high-income countries, the likelihood of age-related neurological decline becomes more prominent.

In Finland, one of the world’s most elderly populations, this demographic reality collides with genetic predisposition and lifestyle-related risk factors. Despite a robust healthcare system, the country is grappling with how to manage long-term care for those living with neurodegenerative diseases.

The role of diagnosis and reporting

Another significant factor contributing to higher death rates in countries like the UK, USA, and the Netherlands is more accurate diagnosis and cause-of-death reporting. In many lower-income nations, dementia may be underdiagnosed or misattributed to other illnesses, skewing global comparisons.

The United Kingdom, for example, has prioritised dementia awareness and early diagnosis through its National Dementia Strategy. While this increases reported death rates, it also reflects better tracking of the disease rather than a genuine spike in cases alone.

Lifestyle and environmental factors

Diet, physical activity, and cardiovascular health are all tied to brain health. Western nations with high rates of sedentary lifestyles, obesity, and heart disease are also seeing a corresponding rise in dementia-related conditions. Countries like the USA and Ireland, where fast food culture and stress-related disorders are prevalent, face additional burdens in this context.

On the other hand, Sweden and Iceland—despite traditionally health ier lifestyles—are also experiencing increases, likely tied to demographic aging and improved health data systems.

According to the latest figures from IHME Global Burden of Disease and Global Terrorism Database, 74% of global deaths are caused by noncommunicable diseases (NCDs)—long-term, often lifestyle-related illnesses that receive relatively little attention in public discourse compared to infectious diseases or violent conflict.

A breakdown of global mortality

The data segments the primary causes of death into three categories:

1. Noncommunicable Diseases (74%)

Leading this category:

This overwhelming majority underscores the need for urgent investment in public health systems, prevention campaigns, and healthier living initiatives to address the rising burden of chronic diseases—particularly in aging populations and increasingly urbanized societies.

2. Infectious diseases (14%)

Despite considerable progress in combating infectious diseases globally, they still represent a significant portion of deaths:

These diseases predominantly affect low- and middle-income countries and remain a top concern for global health organizations working to reduce mortality through vaccination, sanitation, and access to medical care.

3. Injuries, accidents , and other causes (12%)

This category includes both preventable and external factors:

Despite media focus, deaths from war, terrorism, and violence account for only a tiny fraction of global mortality.

Europe: 77.2 years

Europe boasts the highest life expectancy, with an average of 77.2 years. Countries like Spain, Italy, and Iceland have some of the highest life expectancies globally. This region is projected to approach 83 years by 2050.

Northern America: 76.9 years

Northern America, comprising the United States and Canada, has a life expectancy of 76.9 years. The United States has a life expectancy of 76.1 years, while Canada's is 81.1 years. By 2050, the continent is expected to be attaining 94 years.

Australia and New Zealand: 76.5 years

Australia and New Zealand have a combined life expectancy of 76.5 years. Australia's life expectancy is 75.6 years, while New Zealand's is 80.5 years. Australian and Oceanian elders are given a lifespan of 82.1 years in 2050.

Latin America and the Caribbean: 75.5 years

Latin America and the Caribbean have a life expectancy of 75.5 years. Countries like Chile, Costa Rica, and Cuba have made significant progress in increasing life expectancy. Interestingly, this region aims at 80.6 years by 2050.

Asia: 73.5 years

Asia's life expectancy is 73.5 years, with notable variations across countries. Japan has one of the highest life expectancies globally, at 87.2 years, while Afghanistan's is 64.1 years. By 2050, Asia's life expectancy is expected to approach 80 years.

Africa: 63.5 years

Africa has the lowest life expectancy, at 63.5 years. While some countries like Mauritius and Seychelles have made significant progress, others like the Central African Republic and Chad continue to face challenges. With the withdrawal of many health aids supported by USAID, the figures are likely to decline. The UN, however, sees a leap by 5 years in 2050.

According to data from World Population Review , here are the top 7 countries with the lowest cancer rates per 100,000 people:

Sierra Leone: With an age-standardized rate (ASR) of just 35.9 cases per 100,000 people , Niger has the lowest cancer rate globally.

Angola: Following closely, Angola reports an ASR of 76.8 cases per 100,000.

Gambia: Gambia reports an ASR of 79.2 cases per 100,000.

Republic of the Congo: DR Congo has an ASR of 80.7 cases per 100,000.

Nepal: This South Asian country has an ASR of 81.6 cases per 100,000.

Qatar: With an ASR of 82.4 cases per 100,000, Qatar ranks sixth.

Yemen: This Middle East nation reports an ASR of 83.1 cases per 100,000.
