India has a long-standing civilization based on the Varna system, which later evolved into a complex caste-based social structure. This structure has had profound effects on political, social, and economic life. After independence, India undertook several social reforms; however, caste-based data was not officially collected in the decennial census for a long time.
Recently, the central government issued a notification for the upcoming census. According to this, the census in snow-covered regions like Ladakh will begin on 1 October 2026, while in other parts of the country, it will start on 1 March 2027. This time, the caste census has been included, which holds historic significance from both social and policy-making perspectives.
