if a population grows from 1000 to 1600 in 30 years how do I figure out annual the rate of growth.
@keith millan,
This assumes an exponential rate of growth. There are lots of other ways to grow, and this answer will be wrong for any of them.
1000 * (1+N)^30 = 1600
(1+N)^30 = 1.6
1+N = 1.6^(1/30)
N=.0158
