The science of population study is known as demography. Demography is the science that includes all the factors about population and its numbers. Based on the demographic research of the earth, earth’s population up to the year 2050 and 2100 can be estimated by the demographers.

The world’s population is expected to rise to 9.6 billion by the next fifty years and 10.9 billion by the next century, up from 7.2 billion inhabitants living at present, a United Nations agency has predicted.

The United Nations Department of Economic and Social Affairs released numbers for the next hundred years, lifting medium predictions for population augmentation of future years. The UN’s previous best presumption showed population at 9.3 billion in the coming fifty years and 10.1 billion after hundred years from today.

Most of this increase will take place in the un-developed, poorer nations, generally in the middle Africa. John Wilmoth, director of the population distribution at DESA, made clear that the reviews show us the alterations to how countries with high rates of fertility are performing.

Some nations because of their traditions and cultures have nothing such as “birth control” measures and thus average women still giving birth to five children in these poor countries. In comparison to the West, the women give birth to two infants on an average.

Countries like China and India, home to more than the world’s half population, will continue to add numbers in the population until extreme measures are not taken by their respective governments. These developing regions will see growth in the population while high-income nations will more or less remain consistent as of today. These are trends that have been observed by demographic researchers, and one has to wonder if these drifts continue or not.

“We actually don’t make out what these trends will be after a time of some ten years or so,” Willmoth said in a United Nation media assemble on the populace study, explaining that the predictions show a good quality approximation based on the future similar to the past.
