The correct answer is: a) Higher birth rate.
Tamil Nadu has a higher birth rate than the national average. The birth rate in Tamil Nadu is 16.1 per 1,000 people, while the national average is 12.2 per 1,000 people. This means that there are more births per 1,000 people in Tamil Nadu than in the rest of India.
There are a number of reasons for this. One reason is that Tamil Nadu has a younger population than the rest of India. The median age in Tamil Nadu is 27.2 years, while the median age in India is 28.2 years. This means that there are more people of childbearing age in Tamil Nadu than in the rest of India.
Another reason for the higher birth rate in Tamil Nadu is that the state has a lower rate of female education than the rest of India. The literacy rate for women in Tamil Nadu is 72.9%, while the literacy rate for women in India is 65.5%. This means that there are fewer educated women in Tamil Nadu who are able to choose to have smaller families.
Finally, the higher birth rate in Tamil Nadu may also be due to cultural factors. In Tamil Nadu, there is a strong emphasis on family and children. Many families in Tamil Nadu want to have large families, as they see this as a sign of wealth and prosperity.
The higher birth rate in Tamil Nadu has a number of implications. One implication is that the state will have a larger population in the future. This will put a strain on resources such as food, water, and housing.
Another implication is that the state will have a younger population. This means that there will be more people of working age, which could boost the economy. However, it also means that there will be more people who need education and healthcare, which could put a strain on the budget.
The higher birth rate in Tamil Nadu is a complex issue with a number of causes and implications. It is important to understand the reasons for the high birth rate in order to develop policies to address it.
