What the sales data say about Aosta Valley
The Aosta Valley tops the regional table on sales relative to its size. Its 2024 rate of 18.1 transactions for every 1,000 people living there compares with 12.5 for Italy, and no other region comes first on this measure.
In absolute terms the numbers are modest: 2,216 sales in 2024 in the OMI series of the Agenzia delle Entrate, with a provisional 2,561 for 2025 (+15.5%). The valley accounts for 0.3% of Italian transactions and 0.2% of the national population according to ISTAT, so a handful of deals can shift the rate noticeably.
The whole region forms a single province in the series, so there is no provincial breakdown to examine. What can be read is the role of Aosta, the regional capital: the city accounts for 18.5% of valley sales, and the remaining municipalities for the rest. A buyer targeting one commune should treat the regional rate only as background, since volumes say nothing about price levels.
