Life expectancy is a crucial indicator of a nation’s overall health and well-being. It reflects the average number of years a person can expect to live, based on current mortality rates. Variations in life expectancy among countries can highlight disparities in healthcare, lifestyle, and socioeconomic conditions. This article explores the top countries with the highest and lowest life expectancy, providing insights into the factors contributing to these differences. Additionally, we will examine how life expectancy has evolved over the years.
In 2024, the global life expectancy for both sexes stands at an average of 73.4 years. For females, the life expectancy is higher at approximately 76.2 years, reflecting the universal trend of women living longer than men. Males, on the other hand, have a life expectancy of around 70.6 years. This gender gap in life expectancy is consistent across most countries and can be attributed to various factors, including biological differences, lifestyle choices, and healthcare access.

Top Countries with Lowest Life Expectancy
- Chad: Chad has one of the lowest life expectancies in the world at 53.68 years. The country’s health outcomes are severely impacted by limited access to healthcare, high rates of infectious diseases, and widespread poverty. Malnutrition, inadequate sanitation, and lack of clean water exacerbate health issues, leading to high infant and maternal mortality rates. The healthcare infrastructure in Chad is underdeveloped, with insufficient medical personnel and facilities to meet the population’s needs. Addressing these challenges requires significant investments in healthcare, education, and infrastructure to improve life expectancy.
- Nigeria: Nigeria’s life expectancy of 53.87 years reflects the country’s ongoing struggles with healthcare access, infectious diseases, and socioeconomic disparities. High rates of malaria, HIV/AIDS, and other preventable diseases contribute to the low life expectancy. Additionally, Nigeria faces challenges such as political instability, corruption, and inadequate healthcare funding. Efforts to improve life expectancy in Nigeria focus on enhancing healthcare services, increasing immunization coverage, and addressing the underlying social determinants of health. Improving infrastructure and reducing poverty are crucial steps toward better health outcomes for the Nigerian population.
- Lesotho: Lesotho’s life expectancy is 54.91 years, heavily influenced by the high prevalence of HIV/AIDS and other infectious diseases. The country’s healthcare system struggles to provide adequate care and treatment for these conditions, leading to high mortality rates. Poverty, malnutrition, and limited access to clean water and sanitation further compound the health challenges faced by the population. International aid and government initiatives aim to combat these issues, but significant improvements in healthcare infrastructure and socioeconomic conditions are necessary to increase life expectancy in Lesotho.
- Central African Republic: The Central African Republic has a life expectancy of 55.48 years, one of the lowest in the world. The country faces numerous health challenges, including high rates of infectious diseases, malnutrition, and inadequate healthcare services. Political instability and ongoing conflict have severely disrupted the healthcare system, limiting access to essential medical care. Efforts to improve life expectancy focus on stabilizing the political situation, enhancing healthcare infrastructure, and addressing the social determinants of health. Comprehensive and sustained interventions are needed to improve health outcomes for the population.
- South Sudan: South Sudan’s life expectancy stands at 56.51 years, reflecting the country’s significant health and socioeconomic challenges. Ongoing conflict, political instability, and poverty have devastated the healthcare system, resulting in limited access to medical services. Infectious diseases, malnutrition, and poor maternal and child health outcomes contribute to the low life expectancy. Humanitarian aid and international support play crucial roles in addressing these issues, but long-term solutions require peace, stability, and substantial investments in healthcare and infrastructure to improve the well-being of South Sudan’s population.

Life Expectancy by Year
To provide a comprehensive view of how life expectancy has evolved, the following line graph depicts the changes in life expectancy from 1900 to 2024.
The line graph of life expectancy from 1900 to 2024 illustrates a remarkable upward trend, reflecting global improvements in healthcare, sanitation, and nutrition. In the early 20th century, life expectancy was significantly lower due to high infant mortality rates and the prevalence of infectious diseases. However, the mid-20th century marked a turning point with the introduction of vaccines, antibiotics, and public health measures, leading to substantial gains in longevity. The graph also highlights periods of stagnation and decline, often corresponding to wars, pandemics, and economic crises. Overall, the data underscores the importance of sustained efforts in health and social policies to maintain and further improve life expectancy across the globe.
Average Life Expectancy by Continent
The data reveals significant variations in life expectancy among continents. Oceania boasts the highest average life expectancy at 81.0 years, driven by countries like Australia and New Zealand, which have advanced healthcare systems and high standards of living. North America follows closely with an average life expectancy of 79.2 years, reflecting the healthcare quality and economic prosperity in countries like the United States and Canada.
Europe’s average life expectancy stands at 78.4 years, benefiting from widespread access to healthcare and robust social services. South America, with an average of 76.1 years, shows progress but still faces challenges related to economic inequality and healthcare access. Asia’s average life expectancy of 73.2 years reflects the vast disparities within the continent, ranging from high-income countries with excellent healthcare to low-income regions struggling with basic health services.
Africa, with the lowest average life expectancy at 64.3 years, underscores the need for significant improvements in healthcare infrastructure, economic development, and disease prevention efforts. This regional analysis highlights the importance of targeted policies and international cooperation to address health disparities and improve life expectancy worldwide.
Life Expectancy vs. GDP per Capita
Life expectancy and GDP per capita are closely linked, with wealthier countries typically enjoying better health outcomes. Higher GDP per capita allows for greater investment in healthcare, improved living conditions, and better access to medical services, leading to longer life expectancy. For example, countries like Switzerland and Singapore, with high GDP per capita, also have some of the highest life expectancies.
Conversely, nations with low GDP per capita often face inadequate healthcare, poor nutrition, and limited access to essential services, resulting in lower life expectancy. This disparity highlights the importance of economic development in improving public health. By boosting economic conditions, countries can enhance healthcare, education, and living standards, leading to increased life expectancy and overall well-being.
