How did the partition of India affect Delhi’s population in 1947?

The partition of India in 1947 served as a major turning point in the demographic history of Delhi. Following the country's independence, the city experienced a massive influx of Hindu and Sikh refugees who fled from predominantly Muslim Pakistan.12

This sudden and enormous arrival of people was the primary driver of the city's initial population growth after 1947, fundamentally altering its social and demographic landscape. Since that period, Delhi has continued to grow steadily, evolving into a major metropolitan area through ongoing migration from other Indian states and neighboring countries.21
