Japan’s population is likely to hit 1.1 billion by 2070
A report by the Tokyo Metropolitan Government and Tokyo University said the world’s population will rise to 1.21 billion by 2050 from 1.19 billion in 2070.
The study, by researchers from Japan’s National Institute of Population, said the global population of people living in cities will be roughly equal to the total population of the United States of America in 2050.
The researchers said they had looked at how cities’ economies and population have changed in the last century, and concluded that the global economy will continue to grow even as the number of people in cities declines.
The population of Tokyo, which has the world second largest population, will increase by about 400,000 to 2.35 million people, with a population of 2.8 billion by 2100, compared to the current population of 1.8-2.3 billion.
The population growth will occur largely in Japan, with the rest of the world accounting for about 10 per cent of the country’s population.
The report also found that the proportion of Japanese who are over 65 will increase from 25 per cent in 2050 to 30 per cent by 2060, and that the number over 65 in Japan will be about 50 per cent.
The growth in the population of Japan will occur in a time when Japan’s overall population will continue declining.
According to the World Bank, there are about 8.2 million people in the country today, down from a peak of almost 9.2m in the late 1990s.
The number of deaths will also decline from 2.6 million in 2030 to 1 million in 2060.
The research by the researchers found that Japan’s cities, with an estimated total population, would increase by nearly 80 per cent from 2030 to 2060 if its population growth rate of 5 per cent per annum were to continue.
The researchers predicted that, even with a decline in birthrates, the number born in 2030 will still outnumber those aged 65 and over by a ratio of 2 to 1 in 2050 and 1 to 1 by 2080.
A report by United Nations Secretary-General Antonio Guterres and the United Nations Population Fund, published on Thursday, also said that the world is heading towards a “very challenging” situation in the 21st century.
The UN estimates that, by 2040, about one in five children will be underweight and one in four overweight.
