It is bounded by Pakistan and the Arabian Sea to its west and the Gangetic Plains to its east. This is the most heterogeneous of India's regions. The states differ drastically from one another in language, culture and levels of economic development. Maharashtra and Gujarat are among the most industrialized states of India while Rajasthan and Goa are magnets for tourists, though for different reasons.
