Between 1972 and 2002, there were increases in life expectancy at birth in 88% of territories. Large increases occurred in Northern Africa (an extra 10 years), Southern Asia (an extra 13 years) and Asia Pacific (an extra 14 years). Increases were smaller where life expectancy was already relatively high, such as Western Europe and North America. Worldwide the increase was 9 years.
The 12% of territories with no area on this map are those with no change in life expectancy, or a decline. Most of these territories are in sub Saharan Africa where many people live with HIV, and die young.
