a. Death Rate = (Deaths/Total population) x 1000

b. Dependency load = [(pop under 15 + pop over 65)/Total pop] x 100

c. Emigration rate = (Emigrants/Total pop) x 1000

d. Immigration rate = (Immigrants/Total pop) x 1000

e. Infant Mortality Rate = (Infant deaths/Total live births) x 1000

f. Natural Increase Rate = [(Births – Deaths)/Total pop] x 100

g. Net Migration Rate = [(Immigrants – Emigrants)/Total pop] x 1000

h. Pop Growth Rate = [(Births – Deaths) + (Immigration – Emigration)/Total pop] x 100

Pop Growth Rate = Natural Increase Rate + Net Migration Rate

a. Population at end of the year

Starting population = 31 850 000

Pop added: 1 038 000 babies born + 53 000 immigrants = 1 091 000

Pop subtracted: 594 000 deaths (including 93 000 baby deaths) + 86 000 emigrants = 680 000

Thus, pop at end of the year: 31 850 000 + 1 091 000 – 680 000 =

32 261 000

b. The birth rate

Births/Total pop x 1000

Therefore, (1 038 000/31 850 000) x 1000 =

32.59 per 1000

c. The death rate

Deaths/Total pop x 1000

Therefore, (594 000/31 850 000) x 1000 =

18.65 per thousand

d. The emigration rate

Emigration rate = (Emigrants/Total pop) x 1000

Therefore, (86 000/31 850 000) x 1000 =

2.70 per 1000

e. The immigration rate

Immigration rate = (Immigrants/Total pop) x 1000

Therefore, (53 000/31 850 000) x 1000 =

1.66 per 1000

f. The natural increase rate

Natural Increase Rate = [(Births – Deaths)/Total pop] x 100

Therefore, (1 038 000 – 594 000/31 850 000) x 100 =

1.39% (the equivalent of 13.9 per thousand)

g. The net migration rate

Net Migration Rate = [(Immigrants – Emigrants)/Total pop] x 1000

Therefore, (53 000 – 86 000)/31 850 000) x 1000 =

-1.04 per 1000

h. The population growth rate

Pop Growth Rate = [(Births – Deaths) + (Immigration – Emigration)/Total pop] x 100

Therefore, [(1 038 000 – 594 000) + (53 000 – 86 000) / 31 850 000] x 100 =

1.29% (the equivalent of 12.9 per 1000)

i. The infant mortality rate

Infant Mortality Rate = (Infant deaths/Total live births) x 1000

Therefore, (93 000/1 038 000) x 1000 =

89.60 per 1000

j. The total fertility rate

(Number of births/Number of women aged 15 to 45) x 30

Therefore, 1 038 000/9 159 000) x 30 =

3.4 children per woman
