The correct answer is: All of the above.
Tamil Nadu is a state in southern India with a population of over 72 million people. It is the sixth most populous state in India and the third most populous state in the southern region. The state is known for its rich culture and history, as well as its beautiful beaches and temples.
One of the challenges in conducting the Census in Tamil Nadu is the difficult terrain. The state is home to a number of mountain ranges, including the Western Ghats and the Eastern Ghats. These mountain ranges can make it difficult to access some areas, especially during the monsoon season.
Another challenge is the state’s linguistic diversity. Tamil is the official language of Tamil Nadu, but there are also a number of other languages spoken in the state, including Telugu, Kannada, and Malayalam. This can make it difficult to communicate with people in some areas, and it can also make it difficult to collect accurate data.
Finally, the state’s migration patterns can also be a challenge. Tamil Nadu is a popular destination for migrants from other parts of India, as well as from other countries. This can make it difficult to track the population of the state, and it can also make it difficult to collect accurate data on the demographics of the state.
Despite these challenges, the Census in Tamil Nadu is an important exercise that helps to provide a snapshot of the state’s population. The data collected by the Census is used to plan for the future of the state, and it is also used to monitor the progress of the state’s development.
