Stavanger is a city and municipality in Norway. The urban area of Stavanger stretches across many neighboring municipalities, making it the third largest city in Norway by total urban population with 197 852 inhabitants as of January 1, 2011. Stavanger's core is to a large degree 18th- and 19th-century wooden houses that are protected and considered part of the city's cultural heritage. This has caused the town centre and inner city to retain a small-town character with an unusually high ratio of detached houses, and has contributed significantly to spreading the city's population growth to outlying parts of Greater Stavanger. The city's rapid population growth in the late 20th century was primarily a result of Norway's booming offshore oil industry. Today the oil industry is a key industry in the Stavanger region and the city is widely referred to as the Oil Capital of Norway. Multiple educational institutions for higher education are located in Stavanger. The largest of these is the University of Stavanger.

New Haven in the U.S. state of Connecticut, is the principal municipality in Greater New Haven. It is the second-largest city in Connecticut. It was founded in 1638 by English Puritans, and a year later eight streets were laid out in a four-by-four grid, creating what is now commonly known as the "Nine Square Plan", now recognized by the American Institute of Certified Planners as a National Planning Landmark. The central common block is New Haven Green, a 16-acre (6 ha) square, now a National Historic Landmark and the center of Downtown New Haven. New Haven is the home of Yale University. The university is an integral part of the city's economy, being New Haven's biggest taxpayer and employer. Health care (hospitals and biotechnology), professional services (legal, architectural, marketing, and engineering), financial services, and retail trade also help to form an economic base for the city. New Haven had the first public tree planting program in America, producing a canopy of mature trees (including some large elms) that gave New Haven the nickname "The Elm City".

Southampton is the largest city in the county of Hampshire on the south coast of England, and is situated 120 kilometres (75 mi) south-west of London and 30 kilometres (19 mi) north-west of Portsmouth. Southampton is a major port and the closest city to the New Forest. It lies at the northernmost point of Southampton Water at the confluence of the River Test and River Itchen, with the River Hamble joining to the south of the urban area. The local authority is Southampton City Council, which is a unitary authority. Just over a quarter of the jobs available in the city are in the health and education sector. A further 19 per cent are property and other business and the third largest sector is wholesale and retail, which accounts for 16.2 percent. Between 1995 and 2004, the number of jobs in Southampton has increased by 18.5 per cent. Southampton has always been a port, and the docks have long been a major employer in the city. In particular, it is a port for cruise ships; its heyday was the first half of the 20th century, and in particular the inter-war years, when it handled almost half the passenger traffic of the UK. Today it remains home to luxury cruise ships, as well as being the largest freight port on the Channel coast and fourth largest UK port by tonnage, with several container terminals. Unlike some other ports, such as Liverpool, London, and Bristol, where industry and docks have largely moved out of the city centres leaving room for redevelopment, Southampton retains much of its inner-city industry.
