People everywhere are living longer, according to the "World Health Statistics 2014" just published by WHO. Based on global averages, a girl who was born in 2012 can expect to live to around 73 years, and a boy to the age of 68. This is six years longer than the average global life expectancy for a child born in 1990.

 “An important reason why global life expectancy has improved so much is that fewer children are dying before their fifth birthday,” says Dr Margaret Chan, WHO Director-General. “But there is still a major rich-poor divide: people in high-income countries continue to have a much better chance of living longer than people in low-income countries.”

Gaps between rich and poor countries

A boy born in 2012 in a high-income country can expect to live to the age of around 76 – 16 years longer than a boy born in a low-income country (age 60). For girls, the difference is even wider; a gap of 19 years separates life expectancy in high-income (82 years) and low-income countries (63 years).

Wherever they live in the world, women live longer than men. Women in Japan have the longest life expectancy in the world at 87 years.

 “In high-income countries, much of the gain in life expectancy is due to success in tackling non-communicable diseases,” says Dr Ties Boerma, Director of the Department of Health Statistics and Information Systems at WHO. “Fewer men and women are dying before they get to their 60th birthday from heart disease and stroke. Richer countries have become better at monitoring and managing high blood pressure for example.” Declining tobacco use is also a key factor in helping people live longer in several countries.

At the other end of the scale, life expectancy for both men and women is still less than 55 years in nine sub-Saharan African countries. ■
