Expect 11.2 billion population by the end of the century

Thereafter, the report said, India’s population will grow for decades, to 1.5 billion in 2030 and 1.7 billion in 2050, while China’s is expected to remain fairly constant until the 2030s, when it is expected to slightly decrease. China and India, now the countries with the largest populations, are home to more than 1 billion people apiece. 38 billion compared with 1.31 billion in India.

The report places the current world population at 7.3 billion, and projects it will increase to 9.7 billion by 2050 and exceed 11 billion by the year 2100.

Currently, among the ten largest countries in the world, one is in Africa (Nigeria), five are in Asia (Bangladesh, China, India, Indonesia, and Pakistan), two are in Latin America (Brazil and Mexico), one is in Northern America (USA), and one is in Europe (Russian Federation).

India is set to overtake China and become the world’s most populous country in 2022 – six years sooner than previously forecast, the United Nations says.

He noted that understanding the demographic changes that are likely to unfold over the coming years is key to the design and implementation of the new development agenda.

Fast-growing Nigeria is to outstrip the US by about 2050 to become the country with the third largest population, the UN predicted.

Africa will drive more than half of the world’s population growth with the population in 28 of the continent’s countries doubling in 35 years.

John Wilmoth who is the Director of the UN’s Population Division stated that confinement of population growth on some of the most poverty-stricken nations of the world indicates “its own set of challenges”, as it makes it harder to eliminate poverty and inequality, to fight hunger issues and malnutrition, and to increase educational registration and healthcare practices, “all of which are crucial to the success of the new sustainable development agenda”.

Global aging is also examined in the report.

These countries include India, Nigeria, Pakistan, Congo, Ethiopia, Tanzania, the U.S., Indonesia and Ghana.

The revision report confirmed that substantial improvements in life expectancy have been made in recent years.

Life expectancy at birth was also shown to have increased significantly in the least developed countries – from 56 years in 2000-5 to 62 years in 2010-15.

The population estimates and projections from the United Nations are an important benchmark for global trends, as well as for helping provide demographic data to calculate many other important indicators, including health data, around the world.
