Deli Serdang (Indonesian: Kabupaten Deli Serdang) is a regency in the Indonesian province of North Sumatra. It surrounds the city of Medan, and also borders the chartered city Binjai, which is effectively a bedroom community for Medan. The capital of the district is Lubuk Pakam, which is located approximately 30 km east of Medan. Its 2010 census population was 1,789,243 people, but the latest official estimate (for January 2014)is 1,865,695 Medan's new airport in Kuala Namu is in this regency.
Deli Serdang has three plantations owned by London Sumatra (LONSUM).
In June 2004, farmers and indigenous peoples in a number of villages within the district had protested over land ownership of their villages (apparently, the government had leased the land in the villages to LONSUM, but they rejected such leasings and resisted moving). It is said that the authorities had shot farmers and indigenous people attempting to reoccupy the villages.
The national census of 2000 recorded 1,572,768 people, but by 2010 the regency's population increased by 13.76% to 1,789,243; the latest official estimate (for January 2014) is 1,865,695.
