Mumbai, formerly known as Bombay, is the capital of the Indian state of Maharashtra and one of the most populous and vibrant cities in the world, with a metropolitan population of over 20 million. Located on the western coast of India along the Arabian Sea, Mumbai is the country's financial, commercial, and entertainment hub. It is home to the Bombay Stock Exchange (BSE), Reserve Bank of India (RBI), major corporate headquarters, and Bollywood, the world’s largest film industry by volume. The city is a melting pot of cultures, languages, and religions, with Marathi as the official language, though Hindi and English are widely spoken. Mumbai has a tropical climate, characterized by hot summers, a heavy monsoon season from June to September, and mild winters. The city’s infrastructure is a mix of colonial-era buildings, high-rise modern developments, and sprawling informal settlements, reflecting its economic contrasts. Public transportation is extensive and includes the local suburban train network, metro lines, buses, auto-rickshaws, and taxis, making it one of the most connected urban areas in India. Mumbai is known for its fast-paced lifestyle, vibrant street food, cultural festivals, and 24/7 energy. It’s also a city of resilience, having weathered numerous challenges including natural disasters and economic disparities. The cost of living can be high, especially in South Mumbai, but the city also offers a wide range of accommodations, services, and experiences for all budgets. Safety is generally good, particularly in central and tourist areas, though like any large city, caution is advised in crowded places. With a strong blend of tradition and modernity, Mumbai is a city that offers both cultural depth and global ambition, serving as a gateway to India’s diverse identity
