The urbanization has been on a steady rise and is expected to grow by 54% to 66% by 2050, says the revised World Urbanisation Prospects Report released yesterday by the Population Division of the UN Department of Economic and Social Affairs.
Delhi has become the second most populated city in the World, with 25 million population, after Tokyo with 38 million. By 2030, population of Delhi is expected to rise and reach 36 million, where as Tokyo’s population at the same time would decline slightly, and will remain at 37 million, says the study.
By 2030, after Tokyo and Delhi, Shanghai with 23 million; Mexico, Mumbai and Sao Paolo with 21 million each; Osaka with 20 million will make the top five populous cities of the World. The most urbanised region in the world presently is Northern America, where 82% population lives in urban areas. Latin America and Caribbean have 80% living in these areas. Europe has 73%, Africa and Asia have 90% of the population currently in rural areas, which, by 2050 will change to 56% of Africa in urban areas and 64% of Asia living in cities.
Largest urban growth will happen in India, China and Nigeria, which will have 37% of urban population in them by 2050. India and China currently have 30% of world urban population living in their cities. Added to US, Japan, Russia, Indonesia and Brazil, they will have more than 50% of world population living in cities.
“These countries will face numerous challenges in meeting the needs of their growing urban populations, Managing urban areas has become one of the most important development challenges of the 21st century, Our success or failure in building sustainable cities will be a major factor in the success of the post-2015 UN development agenda,” said John Wilmoth, Director of the Population Division.
Growth in rural population has been slow from 1950, and it may reach its peak very soon around 2020, after which, by 2050, it will decrease and will stay at 3.2 billion. Currently there are 3.4 billion living in rural areas. India’s rural population is the highest currently at 857 million, followed by China at 635 million.
