The 60 members of the Chamber of Deputies were elected by proportional representation in four multi-member constituencies; 9 in North constituency, 7 in East, 23 in South and 21 in Centre. Voters could vote for a party list or cast multiple votes for as many candidates as there were seats. Seat allocation was calculated in accordance with the Hagenbach-Bischoff quota.
Voting was compulsory for all citizens between the age of 18 and 75, whilst those over 75 and citizens living abroad were the only ones allowed to vote by post. Failure to vote could have resulted in a fine of between €100 and €250.
The CSV was the largest party in almost every commune (in orange) — as in all elections since the CSV was founded. The DP was the largest in four (in blue) and the LSAP the biggest in three (red).
As in 2004 and 2009, the CSV won pluralities in each of Luxembourg's four circonscriptions. However, the CSV's performance declined in all circonscriptions from 2009. The CSV held up the best in Centre, where it lost only 3.29% compared to its 2009 result. The CSV's sharpest decline was in Nord, where the party lost 5.91%. It nonetheless held a 10% lead over DP in Nord; Nord was the last constituency to not vote for the CSV at the national level, when the DP beat the CSV by 2% in Nord in 1999. Overall, despite a relative decline, the CSV retained a comfortable lead in all circonscriptions, both in votes and in seats.
