This indicator shows the health impacts on New Zealanders from exposure to air pollutants. The indicator focuses on hospital admissions that are the result of exposure to fine particles (ie particles less than 2.5 micrometres in diameter, PM2.5) from human-generated sources, for example, burning wood for home heating.
This measure still needs to be developed.
Currently we are using a proxy measure that models the health impacts of PM10. PM10 is a pollutant of concern because it can cause respiratory problems, and reduce lung development and functioning.
Note: The number of health effects from exposure to PM₁₀ were modelled.
The number of cases per 100,000 population for mortality and hospital admissions were rounded to the nearest whole number and restricted activity days to the nearest 100.
The number of cases per 100,000 population were determined using raw unrounded data.
Population estimates are based on estimated resident population data at 30 June of the given year.
