This question asks us what would increase the population growth over time? so we're not looking at the actual value of that population, so we're not looking at the number of individuals that we're counting.
00:17
Instead, we are looking at the rate of change in that population over time.
00:23
So what would increase the rate of population growth? so if we have a fertility rate less than two, we know that this will not increase the rate of population growth because it will maintain this exponential growth pattern, right? let's say the fertility rate is two.
00:53
Well, that means that with each subsequent generation, there will be a doubling.
00:58
Now, if it's less than two, then this population growth or the rate of population growth will remain constant.
01:12
If we see an increase in mortality rate, right, we would find that it would be very hard to increase the rate of population growth if a lot of individuals are dying.

And the same thing goes with a decrease in birth rate...
