Caltanissetta, in the heart of inland Sicily
Caltanissetta is one of the few Sicilian provincial capitals with no coastline. It lies in the middle of the island, among wheat-growing hills and inland villages. For a long time its economy was tied to the sulphur mines of the surrounding area; today the city relies mainly on public offices, healthcare, education and retail.
One fact sets it apart from Sicily's other provincial capitals: it is classified in seismic zone 3, while all the others are in zone 1 or 2. Across the province, 18 municipalities share zone 3 and four are in zone 2. Expected ground acceleration in the built-up area is also modest, at about 0.073 g. Zone 3 means a moderate hazard, not an absent one: anti-seismic building rules still apply, and for any given building its age, structure and upkeep still count.
Caltanissetta is not the largest municipality among the 22 in its province; by population it comes second, after Gela. In 2023 it had 58,343 residents, 23.6% of the provincial total, compared with 61,711 in 2011, a fall of 5.5%. The estimated average age is about 45 and a half, 24.1% of residents are over 65 (23.3% in the province) and 5.3% are foreign nationals. Households average 2.26 people.
Its role as a provincial capital shows in the services. Overture's open map data count 51 healthcare sites, 55 education sites and 47 sports facilities; for healthcare and sport, provision per resident is well above the provincial rate. Supermarkets (35) are also proportionally more common.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the municipality, so the report can pinpoint the land parcel starting from an address. On hilly terrain cut by valleys and slopes, landslide and flood risk has no single answer for the whole city and needs checking at the precise address.

Caltanissetta is the capital of the province of Caltanissetta, in Sicilia. At the end of 2023 it had 58,343 residents, the second most populous in the province. 24% of the province's residents live here.
Earthquakes
For Italy's Civil Protection Department, Caltanissetta is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (18 of 22) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.073 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.
Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
Landslides and flooding
Landslide and flood risk changes from one street to the next, even within the same municipality: for this reason we do not summarise it as a single figure for the whole of Caltanissetta.
The report checks the exact address against the ISPRA national maps and tells you in plain words whether the building falls within an at-risk area. The official map is also available on IdroGEO.
House prices
We do not publish price tables by municipality. The report gives the minimum and maximum price per square metre for the address's zone, from the Revenue Agency's OMI valuations, with the reference half-year. It is a range for the zone, not the value of a specific home.
Population
Compared with the 2011 census, the resident population has fallen by 5.5%. The estimated average age is 46 years, in line with the province. 24% of residents are over 65 (the regional figure is 23%). Foreign residents make up 5.3% of the population. On average, a household has 2.3 members.
Services
In the official Ministry of Education and Ministry of Health lists, Caltanissetta has 55 schools and 18 pharmacies. The Overture Maps data also lists 35 grocery shops and supermarkets, 51 healthcare facilities, 47 sports facilities and 4 parks and green areas.
There are 0.9 healthcare facilities per 1,000 residents, more than the province average (0.5).
This data is gathered from several providers: services may be missing or closed businesses may still appear. The report counts services within 500 metres and 1 kilometre of the address.
Public transport
We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.
Land registry
The Revenue Agency publishes the cadastral maps for Caltanissetta: the report finds the building's parcel, that is its sheet and parcel number, starting from the address.
