Population of Earth to reach 9.7 billion in 2050

Population of Earth to reach 9.7 billion in 2050

India's population will surpass China's by 2027, and despite being one-third the size of the United States will hold a population 10 times higher than America, the UN has announced.

In the world' populated country by the century ends.

The age group of 65 and over grows the fastest and by 2050, one in six people in the world will be over age 65, up from one in 11 in 2019.

Most of Europe is shrinking and by 2100, its expected to decrease by 120 million people, from close to 750 million today to about 630 million, according to United Nations population data released today.

India is projected to overtake China as the world's most populous country in next 8 years, according to the report.

According to the World Population Prospect released by the United Nations on Monday and analysed by TheCable, the medium-variant projection indicates that the global population could grow to around 8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100. The global population could reach its peak around the end of the current century, with an estimated population of 11 bn.

The overall global fertility rate, which declined from 3.2 births per-woman in 1990 to 2.5 in 2019, is expected to fall further to 2.2 in 2050.

Average lifetime fertility of 2.1 live births per woman is roughly the level required for populations with low mortality to have a growth rate of zero in the long run.

Projections indicate that by 2050 there will be more than twice as many persons above 65 as children under five.

The UN calculates that, without migration, a level of 2.1 births per woman is necessary to merely ensure generational replacement of the population. A growing number of countries are experiencing a reduction in population size. China's population will continue to dwindle and is set to reach 1.1 billion by 2100, while India is expected to have 1.4 billion inhabitants by that time.

The number of countries experiencing a reduction in population size is growing. The population of sub-Saharan Africa is projected to double by 2050 (99 per cent)", the report read in part "Other regions will see varying rates of increase between 2019 and 2050: "Oceania excluding Australia/New Zealand (56 per cent), Northern Africa and Western Asia (46 per cent), Australia/New Zealand (28 per cent), Central and Southern Asia (25 per cent), Latin America and the Caribbean (18 per cent), Eastern and South-Eastern Asia ( three per cent), and Europe and Northern America (two per cent)".

"Some of the largest migratory outflows are driven by the demand for migrant workers (Bangladesh, Nepal and the Philippines) or by violence, insecurity and armed conflict (Myanmar, Syria and Venezuela)".

The report also says deaths are outpacing new births in Belarus, Estonia, Germany, Hungary, Italy, Japan, Russia, Serbia and Ukraine, but that population loss will be offset by an inflow of migrants.
