Explanations:Population density is a critical demographic measure that helps understand the distribution of people across a given area. It is calculated by dividing the total population by the total land area. In the context of Indian union territories, Andaman and Nicobar Islands have the lowest population density, which is a result of their vast land area and relatively small population.
Andaman and Nicobar Islands are a group of islands located in the Bay of Bengal, and they cover a total area of approximately 8,249 square kilometers. Despite this large land area, the population of Andaman and Nicobar Islands is relatively small, with a total population of around 380,000 people as of the 2011 census. This results in a population density of approximately 51 people per square kilometer, which is the lowest among all the union territories in India.
It is important to note that population density can vary significantly between different regions due to factors such as geographical features, economic opportunities, and historical settlement patterns. In the case of Andaman and Nicobar Islands, the low population density is partly due to the challenging terrain and limited economic opportunities, which have historically limited the number of people settling in the region.
Understanding population density is crucial for various applications, including urban planning, resource allocation, and policy-making. It helps in assessing the carrying capacity of an area and in planning for infrastructure and services. In the context of competitive examinations, questions on population density often test the candidate's ability to interpret demographic data and understand the implications of population distribution.
