That said, Moscow would remain Europe's most populated city (according to the UN's classification, Turkey and its largest city Istanbul are part of West Asia).

Cairo, Mumbai, Beijing, and Dhaka all have close to 20 million inhabitants.

The report adds that the world will have 43 "megacities", or urban areas with a population over 10 million, by 2050.

Today, the most urbanized regions include Northern America (with 82% of its population living in urban areas in 2018), Latin America and the Caribbean (81%), Europe (74%) and Oceania (68%).

North America now has the most urbanized regions (with 82 per cent of its population living in urban areas in 2018), while the corresponding figure for Latin America and the Caribbean is 81 per cent, followed by Europe (74 per cent) and Oceania (68 per cent).

The bean counters at the United Nations say Russia's population is still on track to shrink dramatically by 2050, but the demographic decline keeps getting smaller with each forecast. The Guardian reports that now, 55 percent of the world's population resides in urban areas and this will increase to about 68 percent in 32 years.

Meanwhile, reported that the National Population Commission (NPC) had put Nigeria's current population at 198 million people with urban population growing at an average annual growth rate of about 6.5%.

The UN study, carried out by the world body's Population Division, predicts that Tokyo's population will start to decline in the coming two years and that it will be surpassed as the world's largest city by New Delhi towards 2028. Together, India, China and Nigeria will account for 35% of the projected growth of the world's urban population between 2018 and 2050.

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.

There will also be more megacities. DESA stresses that sustainable urbanisation is essential to successful development. The global rural population is now close to 3.4 billion and is expected to rise slightly and then decline to 3.1 billion by 2050.

"When urban growth is rapid, insuring access to housing, water, sanitation, electricity, public transport, education and health care for all is especially challenging", Mr Wilmoth said at a United Nations news conference.

The report recommends governments adopt better integrated policies on infrastructure and social services to improve the lives of urban and rural dwellers.

India's current rural population of 893 million is the largest in the world and is 59.1 per cent of India's total population of 1.35 billion.
