96 departments, 34,848 communes. Start from a region you have heard of, then narrow to a town — median income is free for every one of them, with no account.
Median household income — what people who live there earn. This is not what houses cost.
Town size — how many people live there. The track is logarithmic, so villages get as much of the slider as cities do.
Reading the town data — the dials wake up when it lands.
Eight more criteria come with a subscription — see what each would narrow before you pay for it.
96 of 96 departments have towns that match
Each department shows the median income of its towns — counting every town once, so one city cannot speak for a whole department — and how many towns it holds.
