Currently the world has a population of nearly 7.6 billion people and that's increasing, though at a slower pace than in the recent past. The population is growing at a rate of 1.1 percent, meaning an extra 83 million people are being added to the planet's population every year. The global population is going to surpass 8 billion by 2030 and hit 9.8 billion by 2050, according to a new report
from the United Nations. There's an estimated 962 million people aged 60 and over around the globe (13 percent of the population), and that is going to expand steadily over the coming years. In 2030, 1.4 billion people will be aged over 60 and and that could reach 3.1 billion by 2100.
Ten countries are set to account collectively for over half the world's projected population increase
between now and 2050: India, Nigeria, the Democratic Republic of Congo, Pakistan, Ethiopia, Tanzania, the United States, Uganda, Indonesia and Egypt. Within the next seven years, India is expected to surpass China
as the most populous nation. The United States is also going to be overtaken by Nigeria by 2050 to become the world's third most populous nation - Nigeria is currently posting the fastest rate of population growth worldwide. The following infographic shows the world's most populous nations in 2050 and it was created using the UN's data.
