The correct answer is (a) Himachal Pradesh.
Himachal Pradesh registered the lowest growth of population during the inter Census period 1991-2001. The growth rate of population in Himachal Pradesh was 13.8% during this period, which was lower than the national average of 21.9%. The low growth rate of population in Himachal Pradesh can be attributed to a number of factors, including low fertility rates, high literacy rates, and out-migration of people in search of employment.
Orissa registered a growth rate of population of 17.1% during the inter Census period 1991-2001. Andhra Pradesh registered a growth rate of population of 16.6% during this period. Kerala registered a growth rate of population of 9.4% during this period.
The low growth rate of population in Himachal Pradesh is a positive development, as it will help to reduce pressure on natural resources and infrastructure. The state government should continue to take steps to promote family planning and education, in order to further reduce the growth rate of population.
