DATA IDENTIFICATION
-
-
Name
-
Annual mean levels of fine particulate matter ( e.g. PM2.5 and PM 10) in cities population weighted
-
Indicator purpose
-
The purpose of this indicator is to measure annual mean levels of fine particulate matter in urban areas (cities).
-
Abstract
-
The mean annual concentration of fine suspended particles of less than 2.5 microns in diameters (PM2.5) is a common measure of air pollution. The mean is a population-weighted average for urban population in a country and is expressed in micrograms per cubic meter [mg/m3].

Other characteristics
-
Air pollution consists of many pollutants, among other particulate matter. These particles are able to penetrate deeply into the respiratory tract and therefore constitute a risk for health by increasing mortality from respiratory infections and diseases, lung cancer, and selected cardiovascular diseases.

DATA CONCEPTS and CLASSIFICATIONS
-
-
Classification used
-
Air pollution is the contamination of the indoor or outdoor air by a range of gasses and solids that modify its natural characteristics.
-
Disaggregation
-
The indicator is available by 0.1° x 0.1° grid size for the world.
-
Key statistical concepts
-
The annual urban mean concentration of PM2.5 is estimated with improved modelling using data integration from satellite remote sensing, population estimates, topography and ground measurements.

OTHER ASPECTS
-
-
Recommended uses
-
This indicator is used by the Department of Environment (DOE) to ensure that Belize’s development is sound through effective environmental management for present and future generations.
-
Limitations
-
While the data quality available for urban/rural population is generally good for high-income countries, it can be relatively poor for some low- and middle-income areas. Furthermore, the definition of urban/rural may greatly vary by country.
