Bihar is a state in eastern India. It has a population of over 103 million, making it the 3rd most populous state. Bihar has experienced lagging social and economic development since the 1970s compared to other Indian states. However, improved governance has led to increased investment and economic growth in recent decades in areas like infrastructure, healthcare, education, and reducing crime. Bihar was an ancient center of power, learning, and culture, and was home to India's first empire, the Maurya Empire, as well as the religion of Buddhism.
