Birth Rate, Death Rate, and Fertililty Rate

Calculation

1) Globally: Crude BR= 22, crude DR = 9. r = ?

2) More Developed countries (MDCs) crude BR = 11, crude DR = 10. r = ?

3) LDCs: crude BR = 25 crude DR = 9. r = ?

4) Determine the population change in a country which begins a year with 1 million people, has 1675 births, 450 deaths, 325 immigrants, 150 emigrants: N(1) =

5) Globally, over past 100 years, which has dropped more dramatically? BR or DR? Give three reasons why.
