How has the composition of the Rajya Sabha changed since 1952?

The composition of the Rajya Sabha has changed multiple times due to the reorganisation of States and creation of new ones. For example:

• 1956: Major increase to 220 seats due to the States Reorganisation Act and related laws.
  
  
• 1960–1987: Additional seats were allocated due to the creation of new States/Union Territories such as Nagaland, Goa, Haryana, Meghalaya, etc.
  
  
• Present: The current strength is 245 (233 elected + 12 nominated).
  
  

The Fourth Schedule to the Constitution is periodically updated to reflect these changes.
