6. Trends in Population

7. Demographic Terminology Birth Rate: # of births in a country for every 1000 people in the pop. Total births in one year population size ( in middle of year) X 1000

8. Birth Rate Highest B.R. - Niger 50.54 Lowest B.R. – Japan 7.3 Canada – 10.28

9. Demographic Terminology Death Rate: # of deaths in a country for every 1000 people in the pop. Total deaths in one year population size ( in middle of year) X 1000

10. Death Rate Highest D.R. – Angola 23.4 Lowest D.R. - United Arab Emirates – 2.06 Canada – 7.98

11. Demographic Terminology Natural Increase Rate: difference between Birth Rate and Death Rate of a country BR - DR = NI http://www.worldlifeexpectancy.com/index.php

12. Natural Increase

13. Demographic Terminology Immigration Rate: # of people who permanently move to a country Emigration Rate: # of people who permanently move from a country Net Migration Rate – difference between IR and EM (IR-EM) Trinidad and Tobago -11.2UAE 24.41 Canada 5.62

14. Demographic Terminology Population Growth Rate: rate at which a country’s population is changing. (BR-DR) + (IR - ER) = Pop. Growth

15. Population Growth Rate Highest P.G. – Zimbabwe 4.31% Lowest P.G. – Bulgaris -0.781% Canada - 0.794%

16. Demographic Terminology Dependency Load: % of population that is ≤ 14 years old and 65 and older Age Dependency Ratio: ratio of people in “dependent” ages to those in the “working” ages. Population ≤ 14 + population 65+ population 15-64

17. Age-Dependency Ratio Highest A.D.R. - Uganda 1.12 (11 dependent people for every 10 working) Lowest A.D.R. - United Arab Emirates - 0.3 (3 dependent people for every 10 working) Canada – 0.44

18. Demographic Terminology Infant Mortality Rate: # of children, in a country, who die in the first year of life for each 1000 live births. # of babies that died before 1st birthday Total # of live births in middle ofyear X 1000

19. Infant Mortality Rate Highest I.M.R. - Angola 175.9 Lowest I.M.R. – Singapore 2.32 Canada – 4.92

20. Demographic Terminology Life Expectancy: the average # of years a person is expected to live from birth. Population Pyramid: a special type of graph that summarizes the age and gender structure of a population.

21. Life Expectancy Highest L.E. - Japan 82.25 Lowest L.E. – Angola 38.8 Canada – 81.4

22. Demographic Terminology Total Fertility: average # of children that each woman could have during her fertile years (15-45)

23. Fertility Rate Highest F.R. – Niger 7.6 Lowest F.R. – Singapore 1.1 Canada – 1.58

24. Demographic Terminology Population Pyramid: a special type of graph that summarizes the age and gender structure of a population.

25. Demographic Terminology Replacement Rate: is the total fertility rate that produces a natural increase rate of 0. This value does not take immigration into account Standard replacement rate is 2.1 (country’s population remains the same - no growth)

26. Demographic Terminology Rule of 70: a way to estimate how long it would take for a country’s population to double 70/country’s growth rate = number of years in which a country’s population will double
