Hint: According to the Census of 2011, the state has a population of 13.84 lakhs, that is an increase from the figure of 10.98 lakh that was recorded in 2001 census. The state is located in the north-eastern part of the state and is a part of the seven-sisters state of the north-east.
Complete answer: The decadal growth rate of population of a country or of any place gives an overview of the total population growth in a particular decade. The decadal growth rate is a very important part of census operations.
Option A: Arunachal Pradesh recorded a decadal growth rate of 27.00% in the year 2001, whereas it recorded 26.03% decadal growth rate in 2011.
Option B: According to the census of 2001, the decadal growth rate of the state of Bihar was 28.62%, whereas a decadal growth rate of 25.07% was recorded in the 2011 census. Therefore, Bihar cannot be the correct option as decadal growth of Arunachal Pradesh according to census 2011 exceeds the same of Bihar.
Option C: Jammu and Kashmir recorded a decadal growth rate of 29.43% according to the census of 2001, whereas it is 23.64% according to the census of 2011. Hence, Jammu and Kashmir cannot be the right option either.
Option D: According to the census of 2001, the decadal growth rate of Uttar Pradesh was 25.85%, whereas it is 20.23% according to the census of 2011. So, option D cannot be the correct option as the decadal growth rate of Arunachal Pradesh according to the census of 2011 exceeds the decadal growth rate of Uttar Pradesh.
Therefore, the correct option is option A, Arunachal Pradesh.
Note: Much of the area of Arunachal Pradesh is covered by dense forests and mountain patches. The native people of the state account for about two thirds of the population, while immigrants, mostly of Bengali/ Hindi belt origin, account for a third.
