To calculate the future population the correct formula is Current Population x Total Fertility Rate / 2 x Future Life Expectancy / Current Life Expectancy or CP*TFR/2*FLE/CLE
Look up The World Bank and CIA Factbook for further info.

I don't think this is either A) the correcto formula or B) the correct way to solve it. So i really think this should be in the unsolved problem catergory. in 24 years the earth's population on its current trend of 1.01 would have it way higher than 7.6 billion.
