“A Primer of Demographic Terms”

#5 and 7, page 67


A primer of demographic terms

  • #5, page 67

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

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

  • Emigration rate = (Emigrants/Total pop) x 1000

  • Immigration rate = (Immigrants/Total pop) x 1000

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

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

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

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

  • Pop Growth Rate = Natural Increase Rate + Net Migration Rate


A primer of demographic terms

  • #7, page 67

  • 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 years: 31 850 000 + 1 091 000 – 680 000 =

  • 32 261 000

  • The birth rate

  • Births/Total pop x 1000

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

  • 32.59 per 1000

  • The death rate

  • Deaths/Total pop x 1000

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

  • 18.65 per thousand


A primer of demographic terms

  • The emigration rate

  • Emigration rate = (Emigrants/Total pop) x 1000

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

  • 2.70 per 1000

  • The immigration rate

  • Immigration rate = (Immigrants/Total pop) x 1000

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

  • 1.66 per 1000

  • 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)


A primer of demographic terms

  • 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

  • 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)

  • 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


A primer of demographic terms

  • 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
