The town has 8,397 residents and lies in Loire-Atlantique, Pays de la Loire.
A town with more to fix than most. Crime is the sore point: an average of 12.4 recorded violent incidents and 21.6 recorded burglaries, vehicle thefts, thefts from vehicles and acts of criminal damage per 1,000 residents a year, 2023–2025. Trignac’s overall grade of C− puts it better than 15% of compared French towns, #87 of 93 in Loire-Atlantique. It also trails on health (C−): after allowing for care homes, deaths from 2016 to 2025 were 1% below expected, against 12% below for the median of compared French towns. Fewer journeys need a car (B+): 52% of residents live within 800 m of a bakery, and 16% of working residents walk, cycle or take public transport to work. At the median price of €2,496/m², a 70 m² home costs 6.8 times the median annual income per consumption unit in the Communauté d'agglomération de la Région Nazairienne et de l'Estuaire (CARENE).
