Jalandhar is the centre of the Doaba and one of Punjab's three largest urban economies. Its tehsils are Jalandhar, Nakodar, Phillaur and Shahkot.
Its industry is sports goods, leather, hand tools and publishing. The two Punjabi dailies and much of the Punjabi publishing sector are here.
It holds Phillaur fort, Nurmahal serai, Kartarpur, Talhan, Sansarpur which sent fourteen Olympians, the Desh Bhagat Yaadgar Hall built by the Ghadar returnees, and Dera Sachkhand Ballan, the centre of the Ravidassia movement.
Its Scheduled Caste share was nearly 39 percent at the 2011 census, among the highest in Punjab and among the highest anywhere in India, and it is the district in which the Ravidassia separation happened.
Its emigration is very large and very old, running to Britain from the 1950s and to Canada now.
What is not recorded: the district's village-level caste geography of separate gurdwaras and cremation grounds, which is universally known and nowhere written.
The district is the most densely populated in Punjab and the most urban of the Doaba districts, with Jalandhar city, Phillaur, Nakodar, Shahkot, Adampur and Goraya.
Adampur has the district's airport, opened to scheduled flights in 2016 and running mostly on emigrant traffic. Kartarpur's furniture trade, Goraya's foundries and the hosiery and hand tool workshops along the highway make one continuous industrial strip, almost all of it in units of under twenty workers and almost none of it recorded anywhere.
Its economy is sports goods, leather, rubber, publishing and the emigration business. Its agriculture is potato and vegetables as much as grain.
