Vedclass · Answer

(D) The population growth of a country is determined by the balance between natality (birth rate),mortality (death rate),immigration,and emigration. Specifically,the population density $(N)$ at time $t+1$ is calculated as $N_{t+1} = N_t + [(B + I) - (D + E)]$,where $B$ is birth rate,$I$ is immigration,$D$ is death rate,and $E$ is emigration. Since birth rate,death rate,and emigration are all fundamental components of this demographic equation,the population growth depends on all of these factors.
