The Survival Gap: Why Women Live Longer in Every Corner of the World

Imagine telling your great-grandparents that most people today live past 65. They probably wouldn't believe you. According to research published in The Lancet, global life expectancy has more than doubled since 1900. Yet something even more fascinating emerges when we dig deeper: women consistently outlive men in almost every country on Earth.

The maps below created by Vivid Maps tell this remarkable story. Watch as survival rates change from 1960 to 2015:

The difference is striking, isn't it? According to the World Health Organization, women today outlive men by an average of 5 years globally. But why?

The Science Behind the Gap

The answer isn't as simple as you might think. According to research from Harvard Medical School, several factors contribute to this survival gap:

Biological Advantages

Women have a built-in edge. Their estrogen helps protect against heart disease until menopause, and they have stronger immune systems. Plus, that extra X chromosome provides backup copies of crucial genes.

Behavioral Differences

Here's where it gets really interesting. Studies from the NIH show that men:

Are more likely to skip regular health checkups
Take more physical risks
Are less likely to talk about mental health concerns

The Modern Twist

While better healthcare has helped everyone live longer, the gender gap persists. According to Our World in Data, even in countries with the highest life expectancy, women still live 3-5 years longer than men on average.

A Closer Look at Change

The most dramatic improvements in survival rates happened where you might not expect. For example, research from NLM shows that some countries in Asia have seen life expectancy increase by more than 20 years since 1960.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

Moose population in North America

The moose ( Alces alces ) is the largest member of the deer family, characterized by its massive size, long legs, and distinctive broad, palmate antlers found in males. They have a dark brown or black coat and a humped shoulder. Moose are primarily found in the boreal and mixed deciduous forests of North America, Europe, and Asia. They are solitary animals, often found near bodies of water, and are herbivores that feed on leaves, bark, twigs, and aquatic vegetation. Despite their size, moose are strong swimmers and can run up to 35 miles per hour. The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range. In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale. In 2014-2015, the North Americ...

Map of Fox Species Distribution

Foxes are small to medium-sized members of the Canidae family, which also includes wolves, dogs, and other related animals. There are about 37 species of foxes distributed around the world, and they inhabit a wide range of environments, from forests and grasslands to deserts and urban areas. Below is the map of fox species distribution created by Reddit user isaacSW Here are some of the most well-known fox species and their distribution: Red Fox ( Vulpes vulpes ): The red fox is one of the most widely distributed fox species and is found in North America, Europe, Asia, and parts of North Africa. They are adaptable and can live in a variety of habitats, including forests, grasslands, and urban areas. Arctic Fox ( Vulpes lagopus ): The Arctic fox is found in the Arctic regions of North America, Europe, and Asia. They have adaptations that help them survive in cold climates, such as a thick coat that changes color with the seasons. Gray Fox ( Urocyon cinereoargenteus ): The gray ...
