Population Density  Geo
posted by Jasmine .
predict the number of people that may live on planet earth in 100 years.
how would i figure this out??

ive only been waiting 25 mins and other ppl r getting help like 5 mins later

Jasmine. Hold on. WE answer as we can, first in our primary knowledge areas, then the others. Actually, my kids getting ready for baths first, then. Be patient.

You have to decide what the model wlll be. What has population done in the last 100 years? Do you think that will continue? You estimate is a pure guess. I would base it on the last one hundred years.

how would i do it in population density though??

i know this but how would i do it for the whole world? sperate for every single country??
number of people number
(line) = (line) = ppl
land area number per km2 
I would do it for the entire world: project the increase in world population, and the area stays the same.
