Oh, scientists can make a lot of calculation of how many people are on earth

That’s what you will find out after reading this story:

While most of the estimates in the current population amounts to about 8.2 billion, a new study shows that we can be very insufficiently represented by rural areas.
After analyzing 300 rural dams in 35 countries, researchers at the University of Aalt in Finland have identified the differences between these independent populations and other population data collected in 1975-2010.
Such an insufficient notice may have consequences for the distribution of resources in the country, but other experts remain skeptical that the calculation of the population of decades can be eliminated with such a wide margin.

Homo sapiens There is the most successful species of mammals in the history of the Earth and not even close. These species thrive on almost every continent under various adverse conditions and outperform second place rival-jerk-at least a great billion; However, a new study shows that the impressive nature of humanity proliferation may have been very insufficient.

In most estimates, the people of the Earth make up about 8.2 billion Natural Relations –Claims that these assessments may not be sufficiently represented in rural areas in a large margin.

“We were surprised to learn that the real population living in rural areas is much larger than the global population data show-the number of rural population was not sufficiently estimated at 53 percent to 84 percent during the study period,” Láng-Ritter said in a press release. “The results are amazing because these data sets have been used in thousands of research and widely support decision -making, but their accuracy has not been systematically assessed.”

How exactly do you try the accuracy of global data sets used for population amounts? Well, according to the basics of water resource management, the Láng-Ritter reviewed the data of a different population collected from the village dams 300 such projects from 35 countries to accurately. These data were concentrated in the 1975-2010, and these residents provided a significant set of data to check the other population calculated by organizations such as Worldpop, GWP, Grump, Landscan and GHS-POP (which were also analyzed in this study).

“When the dams are built, large areas flood and people need to be moved,” Láng-Ritter said in a press release. “The population of the convert is usually calculated precisely because the dams a company pay compensation to the victims. Unlike world population data sets, such local impact reports provide detailed, local population that is not adapted to administrative boundaries. Then we combine them with spatial information from satellite images.”

Part of this discrepancy is likely to be due to the fact that many countries do not have the resources for accurate data collection, and difficulties when traveling to distant rural areas only exacerbate the census calculation. The widespread number of rural population worldwide could have had a major impact on those communities, as censuses are most important to find out how to divide resources.

However, not everyone is convinced of this study. Stuart Gietelis-Basten from the Hong Kong University of Science and Technology told the new scientist that although increased investment in rural population data would be useful, the idea that there may be several billions of people on Earth, which we think are very unlikely. “If we are definitely not enough to calculate that huge amount, it is a huge news and contradicts all thousands of other data sets.”

In an attempt to count such a huge population, several hundred, or even a few thousand can slip through cracks. But several millions or even a billion would increase our understanding of human occupation on this planet. Prior to rethinking decades of data collection studies, scientists will need a little more evidence.
