China has a lower fertility rate than its neighbours which can be attributed to its one-child policy.
Low fertility rate has resulted in an increased ratio of ageing population in China accompanied with a very low growth rate.
India would overtake China as the most populous nation in the coming years.
A greater percentage of population in China would have access to urban amenities such as well-developed social infrastructure, improved transport and communication networks.
Both India and Pakistan has a relatively larger population that is probably engaged in agricultural activities.
