Exposure of vulnerable populations to heatwaves

Description

Exposure to extremes of heat results in a range of health consequences, including heat stress and heat stroke, worsening heart disease, and acute kidney injury. Populations over 65, particularly vulnerable to these effects, are being exposed to heatwaves in increasing numbers. This indicator tracks the change in the number of heatwaves experienced by vulnerable populations around the world.

Caveats

As two distinct sources were used for population data, there may be some inconsistencies between the pre- and post-2000 values.
