The world’s world population is expected to peak at 9 billion in 2030, with the majority of people living in urban areas, according to the United Nations Population Fund.
This is in stark contrast to the current rate of growth of the developed world, which is projected to continue to grow at an average annual rate of 1.3%.
The population growth is expected partly because of the economic crisis in many countries, particularly China and India, which are struggling with rising levels of debt.
A quarter of the world population will be 65 and almost two-thirds will be under the age of 65 by 2060, according the UN Population Fund (UNFPA).
The report notes that there will be an increase in the number of people aged 65 and over in the next 30 years, from 7.4 million to 11.3 million, mainly because of migration.
This has already been driven by an ageing population of older people in China and by an increasing number of elderly people living alone in cities.
According to the UNFPA, the population of the countries with the highest fertility rates will be almost 10% in 2030 and about 7% in 2060.
This represents an increase of nearly 7 million people.
The report also notes that the birth rate in China is projected by the UN to be around 3.8 births per 1,000 women, while the fertility rate in India will be around 1.7.
In 2030, about half of all births in China will be to older women, and about one in three births in India.
This will put a strain on the country’s ageing population.
China’s population is forecast to be 7.5 billion by 2090, but the country will continue to be home to over one-third of the population.
The number of women under 30 in China has increased by about 4 million to 8.5 million by 2040.
In India, the number is projected at 4.7 million, with a further 6.7 per cent increase expected over the same period.
The number of deaths in China, India and the US is expected increase to more than three billion by 2030, from about 250 million in 2030.
According to the World Health Organisation (WHO), deaths from chronic diseases will be more than five times as high in China as in the US by 2080.
More than one-fifth of the total world population in 2030 will be aged between 15 and 64, and this will account for one-quarter of the deaths, the report says.
According the UN, more than 60 per cent of deaths are preventable.
A growing number of countries are tackling these problems, particularly in the developing world.
In fact, the majority, including China and the EU, have taken measures to reduce the risk of cardiovascular disease, diabetes and hypertension.
According TOEFL-accredited teaching institutes, teaching methods are increasingly being adopted to improve teaching in the UK.
The UK is the first country in the world to introduce online-only teaching.
The Government is also encouraging more teaching from digital mediums and creating a national teaching platform for teachers to provide more efficient teaching.
