A "World City," also known as a global city, is a significant urban center that plays a crucial role in the global economy. These cities are characterized by their influence in areas such as finance, culture, and politics. Examples of world cities include New York, London, and Tokyo, which are known for their diverse populations and international connections. World cities often serve as hubs for multinational corporations, major financial institutions, and cultural institutions. They attract talent and investment from around the world, making them vital for global trade and communication. Their infrastructure, such as airports and public transport, supports their status as key players in the global landscape.
