The combined municipality has approximately 92,650 inhabitants (January 2024)[7] and is thus the third most populated municipality in Limburg (after Maastricht with 125,000 and Venlo with 103,000 inhabitants). Since February 2020, the city has been governed by a coalition of CDA (Christian Democrats), GroenLinks (Green) and the local parties GOB and Stadspartij.[8]
The highway connecting the centres of Sittard and Geleen, the Rijkswegboulevard, has been rebuilt to be a main route for cycling and walking. The cycling and walking provision is both generous and continuous. Side road junctions, or crossroads, are made 'subordinate'. The carriageways have been narrowed to one 3m lane in each direction. Parking places have been made, in small groups, at the side of the carriageways. These are made to be "not easy to use for larger vehicles," so the road centre is marked as a place for delivery vehicles to stop.[9]
To the west, Sittard-Geleen borders on Belgium, while to the east, it borders on Germany.
