Linear population growth occurs when the population of a city, state or other zone increases by about the same rate every year.

Growth rates of children is not a linear relationship. (The rate of growth changes at different ages).
Linear growth: The population adds the same number every week/month/year.Exponential growth: The population multiplies bythe same number every week/month/year.
Linear population growth occurs when the population of a city, state or other zone increases by about the same rate every year.
They are similar because the population increases over time in both cases, and also because you are using a mathematical model for a real-world process. They are different because exponential growth can get dramatically big and bigger after a fairly short time. Linear growth keeps going up the same amount each time. Exponential growth goes up by more each time, depending on what the amount (population) is at that time. Linear growth can start off bigger than exponential growth, but exponential growth will always win out.
One example of an exponential relationship is the growth of bacteria in a controlled environment, where the population doubles at regular intervals. In contrast, a linear relationship can be observed in the distance traveled by a car moving at a constant speed over time. In both cases, the exponential model captures rapid growth, while the linear model illustrates steady, uniform change.
