"Death rates tend to be highest across middle-income countries
In contrast to the share of deaths that we studied before, death rates are not influenced by how other causes or risk factors for death are changing. Death rates from outdoor air pollution allow us to compare the differences in its mortality impacts between countries and over time.
In this map we see death rates from outdoor air pollution across the world. Death rates measure the number of deaths per 100,000 people in a given country or region.
The global distribution is reflected in the patterns we see when we look at death rates versus income. Death rates tend to rise as countries shift from low to middle-income through industrialization, before falling again at higher incomes as both air pollution and overall health improves."
"Deaths - Cause: All causes - Risk: Outdoor air pollution - OWID - Sex: Both - Age: Age-standardized (Rate)
Variable description	Variable calculated by OWID: the sum of ['Deaths - Cause: All causes - Risk: Ambient particulate matter pollution - Sex: Both - Age: Age-standardized (Rate)', 'Deaths - Cause: All causes - Risk: Ambient ozone pollution - Sex: Both - Age: Age-standardized (Rate)']
Variable time span	1990 – 2019
