Islands stand out in the lower levels
According to , which cites the Security Barometer from the company Verisure Portugal, Porto Santo is described as “one of the safest areas in Portugal”, maintaining “the lowest levels of occurrences” in all the territories analyzed. The same trend is observed on Terceira Island, which presents similar values in the study.
According to the same source, the report is the result of data collected throughout 2025 through the company’s Alarm Receiving Center, which continuously monitors more than one million pieces of equipment across the country.

Lower population density associated with fewer occurrences

The same study adds that Lisbon, Porto, Setúbal and Faro concentrate around 66% of the incidents recorded in 2025.
