Paris is the capital city of France. Situated on the banks of the river Seine in north-central France, it is also the capital of the Île-de-France région, which encompasses Paris and its suburbs. The City of Paris had an estimated mid-2004 population of 2,144,700. The Paris urban area, extending well beyond the city boundaries, has today an estimated population of 9.9 million. The Paris metropolitan area (including satellite towns) stood at 11.5 million in 1999.
It produces more than a quarter of France's wealth, with a GDP of €478.7 billion in 2005. With La Défense, one of the largest business districts in Europe, Paris also hosts the head offices of almost half of the major French companies. Paris is a leading global cultural, business and political centre and has a major international influence in fashion, gastronomy and the arts. It is widely regarded as one of the world's major global cities, with notably the headquarters of many international organisations such as UNESCO, the OECD, the ICC.
