Read the following proposition and statements carefully and answer the questions which follow.
The provisional Census 2011 figures suggest that two contrasting demographic nations are emerging in the country with all four south Indian States  Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, already having achieved the replacement level fertility of 2.1 children per women required to initiate the process of population stabilization, while the four large north Indian States: Bihar, Madhya Pradesh, Rajasthan and Uttar Pradesh, have still a long way to go before they achieve the required level.

(1) This emerging a demographic divide could pose problems for socio-economic developments as well as unity of the country.

(2) Replacement level fertility is the number of children a woman should have to replace herself and her mate for a stable population.

(3) India has been in the middle of the demographic transition over the past several decades where the death rate has fallen sharply because of improved public health as well as sanitation.

(4) The birth rate has remained high in the four large north Indian States of Bihar, Madhya Pradesh, Rajasthan and Uttar Pradesh. Due to slow progress towards socio-economic development as well as limited access to quality reproductive health and contraceptive services.

(5) The use of ante-natal and post-natal as well as family planning services in the four large southern states is satisfactory which leads to slower population growth.
