India has seen a steady decline in agriculture and the primary sector's contribution to GDP, being replaced by growing service sectors like trade, finance, and transportation. The sectors are interdependent - for example, sugarcane farmers, sugar mills, cold drink manufacturers, and transporters all rely on each other for a cold drink to reach consumers. While services have grown rapidly and provided jobs, experts warn high services growth coupled with declining agriculture and industry may not be sustainable long-term. Recent estimates predict services will make up 55% of India's GDP by 2006, showing India is moving to a service-focused economy and helping drive the vision of a developed India by 2020.
