Russia's population will shrink by 11 million people by 2050 and will increasingly be concentrated in cities, according to the latest United Nations estimates.

Despite its lower rate of urbanisation, Asia contains 54% of all urban residents in the world, followed by Europe and Africa with 13% each.

As for rural populations, while they have continued to grow since 1950, it is expected to reach its peak in the next few years, before declining steadily.

Some cities in Japan, North Korea, Poland, Romania, the Russian Federation and Ukraine have already lost population since 2000, it said, citing reasons such as poor economy, natural disasters, low fertility and emigration.

About 90% of the world's rural population live in Africa and Asia. India has the largest rural population (893 million), followed by China (578 million). Shanghai (26 million) and Mexico City and Sao Paulo, with populations of around 22 million each, follow close behind. The organization also said that two-thirds of people in the world will be living in cities by the same time.

The report adds that the world will have 43 "megacities", or urban areas with a population over 10 million, by 2050. Cairo, Mumbai, Beijing and Dhaka all have close to 20 million inhabitants. By 2020, Tokyo's population is projected to begin to decline, while Delhi is projected to continue growing and to become the most populous city in the world around 2028. DESA stresses that sustainable urbanisation is essential to successful development.

Population Division director John Wilmoth said: "When urban growth is rapid, insuring access to housing, water, sanitation, electricity, public transport, education and health care for all is especially challenging".

"However, the challenge is that in many countries it's taking place so rapidly. and large slum areas have developed that are not maybe achieving the goals of sustainable development the way that we would like". "Integrated policies to improve the lives of both urban and rural dwellers are needed, while strengthening the linkages between urban and rural areas, building on their existing economic, social and environmental ties", it said, according to PTI.

The 2018 Revision of the World Urbanization Prospects is published by the Population Division of the United Nations Department of Economic and Social Affairs (UN DESA).
