The global human population will increase by over 2 billion people by 2050, with most growth occurring in India, Pakistan, Nigeria, the Democratic Republic of the Congo, Bangladesh, Uganda, the United States, Ethiopia, and China. Asia will have over 5 billion people, while North America will have only 500 million. Despite declining fertility rates, the population will continue to grow due to longer life expectancy and rising fertility rates in some countries.
The global human population is projected to grow by more than 2 billion people by 2050, the equivalent of one more China and India, in terms of current human population. That comes down to about 75 million people a year, roughly equivalent to the entire human population of Iran.

Most of the world’s human population growth is projected to occur in nine countries: India, Pakistan, Nigeria, the Democratic Republic of the Congo, Bangladesh, Uganda, the United States, Ethiopia and China, in descending order of percentage growth.
Asia alone is projected to have more than 5 billion people by 2050, meaning that about half of the world will live in Asia. North America is projected to have only 500 million people total, 10% that of Asia.
Despite massive human population growth, in some countries fertility among people is declining. In fact, global human fertility is projected to decline by about half of one child per woman by 2050. However, rising fertility among people in some countries, combined with ever longer life expectancy, means that the world’s human population will continue to grow.
