 After World War II, three new neighbourhoods named Westwout, Vogelweide and Bloemenweide were built on the west side of the town, giving the town its current function as the heart of the Zoeterwoude municipality, and a residential center.Attempts to discover more information about the origins of the town were thwarted in October 1981, when an archaeological survey in the centre of the town failed to unveil anything of note.In 2015, the town of Zoeterwoude-Dorp had 4205 inhabitants, which means that in the previous four years the population has shrunk by 280.
