Logistic Growth

Population growth that slows as it nears carrying capacity.

Formula

dNdt=rN(1−NK)\frac{dN}{dt} = rN\left(1 - \frac{N}{K}\right)

Variables

rGrowth rate
NPopulation
KCarrying capacity

Example

Growth stops as N approaches K

Did You Know?

The logistic curve is S-shaped (sigmoidal).
