Since July 2000, 22,500 Danes have moved to Scania. Apart from work related commuting, Swedes cross over to Copenhagen to enjoy shopping and nightlife, to attend cultural and educational institutions and to use Copenhagen Airport. The largest airport in Scania, Malmö Airport is located 47 km (29.2 mi) from Copenhagen Airport and has limited international air traffic. After the opening of the bridge in 2000, an 'Öresund identity' has been promoted in the region in order to counter-act various barriers to cross-border cooperation caused by nationalistic sentiments on both sides. In 1997, a consortium of twelve universities (four Swedish and eight Danish) from both sides of the Sound has been established, opening up all courses, libraries and other facilities to all students, teachers and researchers from the region. The universities have 150,000 students and more than 14,000 researchers combined. The secretariat is located at Lund University and at the University of Copenhagen. The commercial interaction across the border has also significantly increased. In 2018, an average of 19,100 vehicles crossed the bridge each day. The ports of Copenhagen and Malmö were merged in 2001 to form a single company, Copenhagen Malmö Port. This cross-border merger of two ports into one legal entity is the first in history, according to Copenhagen Malmö Port AB, the Swedish registered limited liability company operating the port, a company equally owned by Port of Copenhagen and Port of Malmö. In May 2018 the Øresundsmetro Executive was announced, formed of representatives from the two cities, industry and researchers, to explore the proposal to link Copenhagen and Malmö via a driverless metro system, with travel time of around 20 minutes compared to 35 minutes by train. According to the population registry, as of 2023, 12,872 Swedes live in the Danish regions of the Øresund region and 19,540 Danes in Scania as of 2021. While the number of Swedes in the Danish regions has steadily increased from 10,507 in 2008, the number of Danes living in Scania has decreased from nearly 24,000 in 2009 to 19,540 in 2021. 7,564 Danes live in Malmö, 2,052 in Helsingborg and 862 in Lund, while 5,539 Swedes live in Copenhagen, 937 in Frederiksberg and over 500 in both Gentofte and Helsingør. Political and administrative structure Since 1993, local, regional and national authorities have cooperated in a regional policy forum called the Øresund Committee - from 2016 The Greater Copenhagen & Skåne Committee.
