2001 च्या जनगणनेनुसार महाराष्ट्रात ------ या राज्यातून पुरुष लोकसंख्येचे स्थलांतर प्रमाण सर्वाधिक होते.

The correct answer is Option D (Uttar Pradesh).

Key Points:
• According to the Census of India 2001 migration tables, the largest number of inter-state in-migrants into Maharashtra originated from the state of Uttar Pradesh.
• Economic pull factors—such as employment opportunities, industrial manufacturing, and service jobs in the Mumbai Metropolitan Region (MMR), Pune, and surrounding belts—attracted millions of male migrants from northern states.
• Uttar Pradesh accounted for nearly 30% of all inter-state in-migrants into Maharashtra in 2001, followed by Bihar, Karnataka, and Gujarat.
• Male migration into Maharashtra is predominantly economically motivated (employment/business), whereas female migration across state borders is often linked to marriage and family movement.
• Hence, Uttar Pradesh (Option 4) contributed the highest male in-migration.
• Key Takeaway: Uttar Pradesh accounted for the highest number of male in-migrants into Maharashtra in Census 2001.
