Natality and immigration increases

Vedclass · Answer

(B) The population density $(N)$ at time $t+1$ is calculated using the formula: $N_{t+1} = N_t + [(B + I) - (D + E)]$.Where:$B$ = Natality (birth rate)$I$ = Immigration (number of individuals joining the population)$D$ = Mortality (death rate)$E$ = Emigration (number of individuals leaving the population)Population density increases when the number of individuals added to the population $(B + I)$ is greater than the number of individuals lost from the population $(D + E)$.Therefore,an increase in Natality $(B)$ and Immigration $(I)$ leads to an increase in population density.
