Fort-Mahon-Plage is easy to get around without a car: 53% of residents live within 800 m of a bakery, and 15% of working residents walk, cycle or take public transport to work. The weak point is cost of living (C−): at the median price, a 70 m² home costs 11.5 times the median annual income per consumption unit in the intercommunality.

Source: SSMSI (Interior Ministry), recorded crime by commune, 2023–2025 · Licence Ouverte · For other physical violence, burglary, vehicle theft and theft from vehicles, this figure isn’t published when it’s small (five or fewer in at least one of the last three years); the index uses the département’s average instead, 16.9% of the index here. As that share tops 10%, this Safety Grade carries more doubt than most. Crimes are counted in the commune where they happen, then divided by its residents, so a town that draws people in from around can look higher. The count covers the offense categories the Safety Grade uses.
