Explanations:Population density is a critical demographic measure that indicates the number of people living in a given area, typically expressed as the number of people per square kilometer. In the context of the state of Kerala, understanding the population density of its districts is essential for various planning and administrative purposes.
The 2011 census data provides a comprehensive overview of the population distribution across different districts in Kerala. Among the options provided, Idukki is the least densely populated district. This is primarily due to its geographical characteristics, which include a significant portion of hilly terrain and forested areas. The hilly terrain and limited habitable land contribute to a lower population density compared to other districts in Kerala.
Calicut (Kozhikode) is a more urbanized district with a higher population density due to its economic activities and urban characteristics. Wayanad, while having a lower population density compared to urban districts, still has a higher density than Idukki. Pathanamthitta, another district in Kerala, also has a higher population density than Idukki, making it not the least densely populated district.
Understanding the population density of different districts is crucial for various applications, including resource allocation, infrastructure planning, and policy-making. The data from the 2011 census provides a valuable resource for such analyses and helps in making informed decisions regarding the development and management of the state's resources.
