Helsingborg is a town and the seat of Helsingborg Municipality, Skåne County, Sweden. It had 97,122 inhabitants in 2010. Helsingborg is the centre of the northern part of western Scania. There is no formal metropolitan area, but the municipality of Helsingborg City and its neighbouring five municipalities (within Scania) had in spring of 2013 a population of 269.489 inhabitants at an area of 1.353 square kilometres (0.522 square miles), a population density of 200 people/km2. This makes Helsingborg the fourth largest population area in Sweden.
The city is also Sweden's closest point to Denmark, with the Danish city Helsingør clearly visible on the other side of the Øresund about 4 km (2 mi) to the west, closer than to the city's own remoter areas. If including all population around the northern part of Øresund, as a Helsingborg-Helsingør metropolitan area, its population increases to 732.450 at an area of 2.802 square kilometres (1.082 square miles).
The busy ferry route, known as the HH Ferry route has through history been operated by several shipping lines. As of 2014 more than 70 car ferries departures from each harbour every day.
From the middle of the 19th century onwards, however, Helsingborg was one of the fastest growing cities of Sweden, increasing its population from 4,000 in 1850 to 20,000 in 1890 and 56,000 in 1930 due to industrialization. From 1892 a train ferry was put in service, connecting Helsingborg with its Danish sister city Helsingør. A tramway network was inaugurated in 1903 and closed down in 1967. Plans are underway to reintroduce trams in the city.
