Safety, air quality and noise in Trofa

Safety — higher is safer

Trofa scores 6.9 out of 10 for safety, where higher is safer.

Measured figure: 73.9 recorded offences in 2 published categories per 10,000 residents.

Safety uses 73.9 recorded offences in 2 published categories per 10,000 residents for the whole município, from Offences recorded by the Portuguese police forces (PSP, GNR and the municipal and maritime police), compiled by the Direção-Geral da Política de Justiça and published by INE by município, 2021 to 2025, 2025, so this figure describes the whole region, not a neighbourhood inside it.

Clean air — higher is cleaner

Trofa scores 7.9 out of 10 for clean air, where higher is cleaner.

Measured figure: 7.7 micrograms per cubic metre PM2.5 annual mean.

Clean air uses a median of 7.7 micrograms per cubic metre of PM2.5 across 75 points sampled evenly across this NUTS 3 region, an annual mean from the Copernicus CAMS regional background surface. This figure is approximate: a regional background estimate rather than a local modelled surface.

This score is approximate.

Quiet — higher is quieter

Trofa scores 6.4 out of 10 for quiet, where higher is quieter.

Measured figure: 48.0 decibels (modelled).

Quiet uses a median of 48 decibels of modelled outdoor sound across 75 points sampled evenly across this NUTS 3 region, a day-evening-night level from the national major-road traffic noise model, where a lower reading means a quieter area. Points are spread by area rather than by population, so a large rural district reads quieter than the towns inside it. This figure is approximate: modelled from the major-road network rather than a local noise surface.

This score is approximate.
