Deagel is supposed to be the authority on quick facts on all countries. Deagel gathers information from the following Sources: US Department of Defense, Department of State, CIA, World Bank and European Union.
Deagel does 10 year projections. Deagel head was asked why the drastic change in U.S. population and he said hackers got to the database and changed numbers and that the numbers would be changed once they rectified the problem, this was last October. In the report you will notice not the U.S. but other allied countries suffer major depopulation like: Netherlands, Canada, England, Spain, Portugal Australia and many more. Arab and South American countries actually have large increases. Here is a link if interested.

I should add that last Fall the numbers were listed as a 2025 projection of 69 million for U.S. but Deagel did change those numbers to 65 million total U.S. population.
