| 42nd Amendment Act | 1976 | Froze the delimitation of Lok Sabha and State Assembly constituencies based on the 1971 Census population figures until the year 2001. This was done to encourage family planning programs, as states with lower population growth would not be penalized by losing political representation. | This amendment directly impacted the application of population distribution data for political representation. By freezing the number of seats and their boundaries, it temporarily delinked the actual population distribution from electoral geography, leading to significant disparities in the population size of constituencies over time, especially between states with varying population growth rates. It highlighted the political sensitivity of using population as a criterion for resource and power distribution. |
| 84th Amendment Act | 2001 | Extended the freeze on delimitation of Lok Sabha and State Assembly constituencies for another 25 years, i.e., until the first census after 2026. However, it allowed for readjustment of constituencies within a state based on the 1991 Census figures, without altering the total number of seats allocated to the state. | This further prolonged the impact of the 42nd Amendment on population distribution and political representation. While it allowed for internal readjustments to reflect population shifts within a state, the inter-state allocation of seats remained based on 1971 figures. This continues to create a mismatch between current population distribution and political power, particularly disadvantaging states that have successfully controlled population growth and benefiting those with higher growth rates. This has significant implications for federal relations and resource allocation, as population is a key factor in Finance Commission recommendations. |
