Key Observations and Notes:

• Panchayats: The number of Gram Panchayats has steadily increased over time, reflecting population growth, administrative reorganization, and efforts to strengthen local self-governance, especially after the 73rd Constitutional Amendment.
• Blocks (Panchayat Samitis): The number of Blocks (Panchayat Samitis) has also evolved, generally increasing with the expansion of rural development programs and the three-tier PRI system. The current figure is mostly cited as 81 Panchayat Samitis or around 78 Development Blocks.
• Assembly Constituencies: The number of Assembly seats saw significant changes during the initial formation and reorganization phases (Part C state, Union Territory, merger of Punjab areas, and finally statehood). It has been stable at 68 since the 1972 delimitation, with further internal delimitation in 2008 not changing the total number.
• Lok Sabha Constituencies: The number of Lok Sabha seats fluctuated slightly in the early years, notably increasing to 6 in 1967 after the merger of Punjab areas, but has been consistently 4 for a long period, including the present.
