While most estimates put the current human population about 8.2 billion, a new survey suggests that we may be significantly insufficiently presenting rural areas.

Analyzing 300 projects for rural dams in 35 countries, researchers at the University of Aalto in Finland have found inconsistencies between these independent population and other population data collected between 1975 and 2010.

Such underestimation may have consequences for the distribution of resources within a country, but other experts remain skeptical that decades of population count can be excluded with such a large margin.
Homo sapiens is the most successful species of mammals in the history of the earth and is not even close. The species thrives on almost every continent, under different adverse conditions and exceeds the contender in the second place-the redby at least a cool billionS A new study, however, suggests that the impressive nature of the spread of humanity may have been significantly reported.
Most estimates put the human population on Earth at about 8.2 billion, but Joseas Lang-Rerier-Directorate at the University of Aalto in Finland and a lead author of the study published in the magazine Natural Communications –Allegations that these estimates may be insufficiently presenting rural areas with a significant margin.
“We were surprised to find that the actual population living in rural areas is much higher than the global data on the population-depending on the set of data, rural populations are underestimated between 53 percent to 84 percent during the study period,” says Lang-Rerier. “The results are remarkable as these data sets have been used in thousands of studies and widely supported decision -making, but their accuracy is not systematically evaluated.”
How exactly do you test the accuracy of the global data sets used to extract common population in the first place? Well, with experience in water resources management, Lang-Rerier examined a different type of population data collected from rural dams in rural areas-300 such projects in 35 countries to be accurate. These data focused on the years from 1975 to 2010, and these population waistlines provided a significant set of inspection data against other amounts of the population, calculated by organizations such as WorldPop, GWP, Grump, LandScan and GHS-POP (which were also analyzed in this study).
“When dams are built, large areas are flooded and people need to be moved,” Lang-Reriers said in a press statement. “The moved population is usually counted precisely because the dam companies pay compensation to those affected. Unlike the global population data sets, such local impact reports ensure comprehensive, ground number of population not distorted by administrative limits. We then combined those with spatial information from satellite.”
Part of this discrepancy probably stems from the fact that many countries do not have resources to accurately collect data, and the difficulty of traveling to distant rural areas only exacerbates differences in the census census. The widespread insufficient presentation of the rural population around the world can have a deep impact on these communities, since the census is central to inventing how to divide resources.
However, not all are convinced of this study. Stuart Gettel-Baise of Hong Kong University of Science and Technology told the new scientist that although increased investments in collecting population data in rural areas would be helpful, the idea that Earth could contain several billion more human residents, which we thought was extremely unlikely. “If we really underestimated this huge sum, it is a large -scale news and contradicts all the years of thousands of other data sets.”
When trying to count such a massive population, several hundred or maybe even a few thousand can sneak through the cracks. But several million or even billion Would you raise our understanding of the human occupation of this planet. Scientists will need a little more evidence before rethinking decades of studying the data set.
