ANt + 1 = Nt + [(B + I) – (I + E)]

BNt + 1 = Nt + [(B + I) – (D + E)]

CNt + 1 = Nt + [(B + D) – (B + E)]

DNt + 1 = -Nt + [(B + I) – (D + E)]

Answer:

The population density at time t+1 is given as Nt + 1 = Nt + [(B + I) – (D + E)].
Here Nt is population at time t, B is natality, I is immigration, D is mortality while E is emigration.
