The age pyramid
Each bar is a five-year band, men on the left and women on the right, scaled to the commune's largest band. A dip between 20 and 35 marks a commune young adults leave for want of housing they can afford; a bulge at 40-55 with plenty of children, a commune of settled families.

Since 2020
Working residents and jobseekers living in the commune, whatever country they work in. The rate is the second over the active population — it says nothing about the cross-border workers who commute in.
STATEC attaches a warning to this table, repeated here: IGSS and ADEM place a resident in a commune by postal code, and some postal codes straddle two communes. The series is for reading a commune against the country and against its own past; it is not for separating two neighbouring villages by a decimal.

The largest communities
This says where a community is present, not whether it is organised: a commune can be 30% Portuguese with no association, and 4% British with a rugby club. Read it as a clue to the language you will hear in the supermarket.

How to read these shares
The register counts every nationality held: Luxembourg naturalises without requiring the first passport to be surrendered, so a sizeable share of residents appears twice. Country totals run about 18% above the population nationally. Every share shown here is therefore taken against the population, which makes the Luxembourgish share exact and lets the communities add up to more than 100 per 100 residents.
The 100 Luxembourgish communes only. The register is national, and the French, Belgian and German equivalents are neither harmonised with each other nor published per commune for the border strip — so the 27 neighbouring cities in the perimeter get no page here rather than an estimate.
