The U.S. population in 1990 was approximately 250 million, and the average growth
rate for the past 30 years gives a doubling time of 66 years. The above formula for the
United States then becomes
P (in millions) = 250 times 2( y-1990)/66
What will the population of the United States be in 2025 if this
growth rate continues?

Plug 2025 in the equation for y
subtract within the parethesis
divide out the exponent
multiply 2 by the exponent
multiply by 250
P=250*2^(2025-1990)/66
P=250*2^35/66
P=250*2^.53
P=250*1.44363
360.9075

That most likely depends on whether or not there is, or perhaps I should say when there is a world war 3, and just how devastating it turns out to be.

Ok. So, are we factoring in natural disasters, peaceful religions who think that everyone ELSE must die, and your average, run-of-the-mill joe shmo who goes postal and guns down a couple of dozen people plus himself?
