Annual average levels of fine particulate matter in cities (population-weighted). The Urban Air Quality Indicator PM2.5 presents the evolution of the population-weighted average annual mean concentration of PM2.5 and compares it with the target value established since 2010 by current legislation.
They are calculated for the total population living in municipalities with more than 50,000 inhabitants. For each pollutant, the average value of all the stations belonging to each of the municipalities with more than 50,000 inhabitants with a sufficient number of valid data is calculated and multiplied by the population of that municipality. The sum of these values for all the populations divided by the total population of these cities or autonomous communities allows the weighted average to be obtained.
For the calculation of the indicators, those stations that have participated in the evaluation of air quality (of any type: traffic, industrial and background) that are located in municipalities with more than 50,000 inhabitants (urban environment) have been used. A city can have one or several stations, and each city is assigned the average of its stations as an indicator. The total number of stations considered in the calculation of the indicators varies throughout the period, and even in the evaluation of each variable, which is a very important aspect that conditions the final result.
To aggregate the different municipalities, the indicator for each city is weighted by its population.

Spain has always had high levels of particulate matter, the concentration of which is sporadically increased naturally by intrusions of African dust. For this reason, current legislation establishes a procedure whereby the contribution of PM10 and PM2.5 due to natural sources can be discounted for the purposes of compliance with the legislated values. Measurements of PM10 and PM2.5 in urban areas provide partial information on air quality problems and must be supplemented with information on other pollutants, as well as socio-demographic information and atmospheric conditions (precipitation levels, wind action) in urban areas.
The indicator is prepared by the Subdirectorate General for Clean Air and Industrial Sustainability. Directorate General for Environmental Assessment and Quality. Ministry for Ecological Transition and the Demographic Challenge, and is published annually as part of the products and services of the National Statistics Institute, as part of the quality of life indicators, section 8 Environment and surroundings, 8.1 Pollution and noise, indicator 8.1.3.
