France's cheapest square metres sit on near-average incomes
Overlay income and price on France's communes and earnings barely move as prices climb: the cheapest quarter of the property market sits on a median income of 20,450 per year, against 24,320 in the dearest — a gap of under a fifth.
GeoDwel's French map lets you stack two official layers on the same commune: median disposable income from INSEE Filosofi, and the median transaction price per square metre from the DVF deeds register. Across metropolitan France the middle commune earns 22,060 per year and trades at 1,593 per square metre. The interesting reading is not the averages but how loosely the two move together.
Price climbs, income holds
Sort communes into four equal price bands and local earnings barely stir. The cheapest quarter — from 159 to 1,189 per square metre — sits on a median income of 20,450 per year, only a little below the national middle. The dearest quarter costs several times as much per square metre yet its residents earn 24,320, less than a fifth more. Property is doing almost all the moving.
The gradient runs the other way
Read the layers from the income side and the slope is far steeper. Communes in the top income quartile trade at 2,377 per square metre; those in the bottom at 1,215 — close to double. Higher earnings pull prices up hard; higher prices pull earnings up gently. For a buyer that asymmetry is the point: France's cheapest square metres are not, on the whole, its poorest places.
The inconvenient trait
Two gaps sit under the map. DVF only prices communes with at least five recorded sales, so the thinnest inland villages — often the cheapest of all — simply drop out; 31,105 communes carry a price. Income is missing for more still. And the national extremes belong to large towns: among communes above 5,000 residents, price runs from 624 to 14,628 per square metre. The affordable inland pocket is real, but the map cannot see the smallest of them.
