Grosseto, the heart of the Maremma
Grosseto is the main town of the Tuscan Maremma: a lowland city on the river Ombrone, a few kilometres from the Tyrrhenian Sea, which grew mostly after the marshes around it were drained. Its old core is still enclosed by the hexagonal Medici walls, and the municipal area reaches the coast at the seaside village of Marina di Grosseto.
Among Tuscany's provincial capitals, Grosseto has one of the lowest seismic classifications: zone 4, the lowest of Italy's four classes. Its province is mixed, with 10 municipalities in zone 4, 16 in zone 3 and 2 in zone 2. Expected ground acceleration in the built-up area is about 0.065 g, moderate but close to the low band. Zone 4 does not mean ignoring the issue entirely: for an older building, the state of the structure is still worth asking about.
The population is growing. At the end of 2023 there were 81,482 residents, 3.6% more than in 2011, which is 37.8% of the entire province. The town is also younger than the area around it: an estimated average age of 47.6 against 49.1 for the province, with over-65s at 26.4% compared with 29.0%. Foreign residents make up 9.3%.
Overture Maps data show 93 healthcare facilities in Grosseto (1.14 per 1,000 residents, above the provincial average of 0.69) and 120 sports facilities. The Ministry of Health lists 26 pharmacies, 0.32 per 1,000 residents, below the provincial average of 0.43.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Grosseto too, so the report can reach the sheet and parcel numbers (foglio and particella) from an address. On a plain crossed by a large river and facing the coast, flood and landslide hazard and the local price range should be checked at the precise address.

Overview
Grosseto is the capital of the province of Grosseto, in Toscana. At the end of 2023 it had 81,482 residents, the most populous municipality in the province. 38% of the province's residents live here.
Earthquakes
For Italy's Civil Protection Department, Grosseto is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Only 10 of 28 municipalities in the province are in zone 4.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.065 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.
In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.
Population
Compared with the 2011 census, the resident population has grown by 3.6%. The estimated average age is 48 years, lower than the province average (49). 26% of residents are over 65 (the regional figure is 26%). Foreign residents make up 9.3% of the population. On average, a household has 2.1 members.

In tax year 2024, taxpayers in Grosseto declared an average taxable income of 24,352 euros, above the provincial average (22,706 euros). The Italian average is 24,895 euros.
Grosseto is in climate zone D, with 1,550 heating degree days: heating may be switched on from 1 November to 15 April, for up to 12 hours a day. The same table puts the town hall at 10 metres above sea level.

Radon and contaminated sites
Grosseto is not among the radon priority areas designated by the Regione Toscana in 2025. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.
Official databases list 8 contaminated sites, or sites still under investigation, in Grosseto, and 18 more have been cleaned up or closed. The report tells you whether one is close to the address.
Landslides and flooding
Landslide and flood hazard changes from one street to the next even within Grosseto: the report checks the address against the ISPRA maps.
House prices
The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.
Land registry
The cadastral maps for Grosseto are public: from the address the report finds the sheet and parcel number.
Liveability area by area
The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 937 inhabited census areas in Grosseto. Half of the residents live in areas scoring 70 or more.
Residents by band
- modest 1.1%
