Diskit is a small, tight-knit community. According to the most recent accessible census data (2011), the immediate village area has a population of approximately 1,700 residents, though this number swells significantly during the summer months due to an influx of tourism workers, seasonal vendors, and military personnel.
The population is predominantly composed of ethnic Ladakhis. Tibetan Buddhism is the majority religion, which profoundly influences the daily rhythm, culture, and architecture of the town, alongside a minority Muslim population. The primary language spoken is Ladakhi (a Tibetan dialect), though Hindi and English are widely understood and spoken, especially among the younger generation and those working in tourism.
