Which is the 1st richest city in India

Mumbai is India's richest city when measured by total economic output, wealth concentration, and number of high-net-worth individuals, functioning as the country's financial capital and commercial hub. The city generates approximately 6-7% of India's entire GDP despite housing only about 1-2% of the population, hosts the headquarters of the Reserve Bank of India, both major stock exchanges (BSE and NSE), most large banks and financial institutions, and serves as home to the majority of India's billionaires and millionaires. Mumbai's economy spans finance, entertainment (Bollywood), trade, manufacturing, and services, with the Mumbai Metropolitan Region representing one of the world's most economically productive urban agglomerations.

However, when measuring by per capita income or average prosperity per resident, Delhi/New Delhi and certain tier-2 cities show higher numbers, as Mumbai's enormous population (over 20 million in the metropolitan region) includes vast slum settlements alongside extreme wealth, creating stark income inequality. Bengaluru has challenged Mumbai's dominance in recent years through IT sector growth and startup valuations, while Delhi serves as the political capital with significant governmental and service sector wealth. For businesses and job seekers, Mumbai remains India's primary destination due to unmatched opportunities in finance, corporate headquarters, creative industries, and international connectivity through its port and airport. The city's wealth is visible in its luxury real estate (some of the world's most expensive per square foot), high-end retail districts, stock market activity, and concentration of corporate decision-making, though this prosperity contrasts sharply with challenging living conditions for millions of residents struggling with housing costs, congestion, and infrastructure strain.
