Serradifalco, wheat fields and hills in inland Sicily
Serradifalco is an inland Sicilian town at around 500 metres, surrounded by wheat fields, almond groves and olive trees. It lies in the western part of the province of Caltanissetta, towards Canicattì and the Agrigento area. For the hospital, public offices and secondary schools, people go to Caltanissetta, a short drive away.
The figure that matters most for the housing market is the falling population. At the end of 2023 there were 5,456 residents, down 12.9% on the 2011 census, or 809 fewer people. Emigration has been emptying many towns in the Sicilian interior. In the old centre it is easy to find houses that stand empty or open only in summer, often stone-built and in need of work, so low asking prices have to be weighed against renovation costs.
Residents are older than the provincial average: the average age is 47.0 against 45.2, and 25.8% are over 65 compared with 23.3%. Foreign residents are very few, at 2.0%. Average declared incomes are below the provincial figure. The climate is classed as zone D, with hot summers and winters cooler than on the coast, so heating is a real cost.
Compared with much of Sicily, earthquake hazard here is limited. Serradifalco is in seismic zone 3 of the Civil Protection classification, along with 17 other municipalities in the province, while 4 are in zone 2. The expected ground acceleration in the built-up area is about 0.066 g. In older houses the condition of the roof, the timber floors and the walls matters most.
The clay soils of this part of Sicily shift easily on slopes, so for houses on the edge of town it is worth checking how stable the ground is. The report does this for the address using the official maps, and the Revenue Agency (Agenzia delle Entrate) cadastral maps let it find the land parcel.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
