The Grand Duchy of Luxembourg is divided into cantons, which group the communes (= municipalities).
Luxembourg was divided into three districts until their abolition in October 2015:[1] There are a total of 12 cantons, which were previously a subdivision of the districts but are now the first-level subdivision of Luxembourg:[1][2] The communes (municipalities) are the lowest administrative division in Luxembourg.
[2] Below the official administrative level of the commune, Luxembourg City has further unofficial administrative subdivisions, known as quarters.
The twenty-four quarters[3] of Luxembourg City are a de facto subdivision without legal basis used to simplify public administration.
[citation needed] There are four electoral constituencies of Luxembourg: Centre, East, North, and South.
