Q9462. What is the population density of Jaisalmer district as per the 2011 Census?
Explanation
Jaisalmer district is known for having the lowest population density in Rajasthan and among the lowest in India. According to the 2011 Census, the density was recorded at only seventeen persons per square kilometer. This extremely sparse distribution of people is primarily due to the vast, arid desert terrain and the severe scarcity of water and other essential resources.
