If natality is represented by $B$,mortality by $D$,immigration by $I$,emigration by $E$,and population density by $N$,then the population density at time $t+1$ is represented by:

  • A
    $N_{t+1} = N_t - [(B+I) - (D+E)]$
  • B
    $N_{t+1} = N_t + [(B+I) - (D+E)]$
  • C
    $N_{t+1} = N_t + [(B+I) + (D+E)]$
  • D
    $N_{t+1} = N_t - [(B+I) + (D+E)]$
