What geographical trend is observed in the origin of early installation artists?

They primarily came from big cities

Answer: They primarily came from big cities
Most early installation artists, like Nalini Malani and Vivan Sundaram, came from big cities.

The art form that was increasingly seen as contemporary in the 1990s was installation. It provided a way to combine painting, sculpture, photography, video and even television in one space. This medium, which could spread out into a whole hall could fully grab the attention from all sides. On one wall, you could see a painting, while on another, a video with sculptures hanging from the wall with photographs displayed in glass cases. It offered a new immersive experience, which affected almost all our senses. However, it was more dependent on technology and it is, therefore, not surprising that most of the early installation artists came from big cities — Nalini Malani from Mumbai and Vivan Sundaram from Delhi. However, their subject matter was grim and thought provoking.
