Population Ecology. Population Demographics. Demographics are the various characteristics of a population including, Population Size, Age Structure, Density, and Distribution Demographics allow one to determine the ecological and evolutionary relationships between various species populations.
r = [(births + immigration) – (deaths + emigration)]
G = r x N
N1 = (r x N) + N
N2 = (r x N1) + N1
G = r x N [(K-N) / K)]
N1 = (r x N [(K-N) / K)]) + N
N2 = (r x N1 [(K-N1) / K)]) + N1
