San Giorgio Ionico, a short drive from Taranto
From San Giorgio Ionico to Taranto is only a few kilometres by road, and for many residents the city is where they work, study and go to hospital. The town lies on the plain east of Taranto, on slightly raised ground, surrounded by olive groves and vineyards like the small towns around it.
The population is falling: 14,062 residents in 2023, 10.3% fewer than in 2011, or 1,614 people. As across the Taranto area, many young people have left for northern Italy or abroad. The average age is 46.4, almost the same as the province, and foreign residents are few, at 2.0%.
For buyers this means a wide choice of detached houses and flats, often in need of renovation, at prices that stay moderate. Average income is slightly above the provincial figure. Overture Maps data record 18 supermarkets and 17 healthcare facilities, more per resident than the provincial average, a sign that the town also serves its neighbours.
Seismic hazard is low: San Giorgio is in zone 4 of the national classification, with an expected ground acceleration of about 0.061 g. In a 1960s or 1970s house, look above all at flat roofs and leaks, at the wiring and plumbing and at insulation. Winters are mild and summers long and hot, so keeping cool in August matters as much as heating.
In the lower parts of the countryside, where heavy rain collects, the report checks flood hazard for the address. It also measures how far schools, pharmacies and shops are from the exact house.
Key points
- A few kilometres east of Taranto, among olives and vines.

Overview
San Giorgio Ionico is a municipality in the province of Taranto, in Puglia. At the end of 2023 it had 14,062 residents, ranked 12 of 29 municipalities in the province.
Earthquakes
For Italy's Civil Protection Department, San Giorgio Ionico is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (19 of 29) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.061 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 fallen by 10.3%. The estimated average age is 46 years, in line with the province. 25% of residents are over 65 (the regional figure is 24%). Foreign residents make up 2.0% of the population. On average, a household has 2.4 members.

In tax year 2024, taxpayers in San Giorgio Ionico declared an average taxable income of 21,826 euros, above the provincial average (20,557 euros). The Italian average is 24,895 euros.
San Giorgio Ionico is in climate zone C, with 1,258 heating degree days: heating may be switched on from 15 November to 31 March, for up to 10 hours a day. The same table puts the town hall at 75 metres above sea level.
