The Evolution of Life Expectancy Globally
A Historical Overview of Life Expectancy
The past two hundred years have witnessed considerable advancements in human health and longevity. In the early 1800s, the average life expectancy worldwide did not exceed 40 years, a reflection of the harsh realities of extreme poverty, inadequate medical services, and unsanitary conditions. However, by the mid-20th century, significant improvements were evident, particularly in Europe, North America, and certain regions of South America, where the average life expectancy had risen above 60 years. For instance, Norway had a life expectancy of 72 years, whereas Mali had a significantly lower life expectancy of 26 years.
Progress in Life Expectancy from 1950 to 2000
The latter half of the 20th century saw remarkable progress, especially in Asia and Latin America, mirroring global initiatives to enhance health and living standards. The UN World Population Prospects 2022 anticipates these trends to persist, predicting that by 2050, most regions worldwide will have an average life expectancy exceeding 80 years at birth. This infographic encapsulates these transformative changes, offering an optimistic perspective on the future of global health.

Factors Contributing to Improved Life Expectancy
The increase in life expectancy can be credited to several factors, including advancements in medical technology, improved healthcare infrastructure, enhanced sanitation, access to clean water, and heightened awareness about health and nutrition.
Life Expectancy in Historical Context
While it may seem like the rise in life expectancy is a given in today's world, it's important to remember that for much of history, this wasn't the case. As indicated in the chart, for the majority of human history, life expectancy at birth hovered around the 20-30 year range. It wasn't until the mid-19th century that improvements in sanitation, access to clean water, and other factors led to the consistent and exponential progress we witness today.
