World Population Patterns
How many years did it take for the world’s population to increase from: a) 1 billion to 2 billion b) 2 billion to 3 billion 3 billion to 4 billion 4 billion to 5 billion e) 5 billion to 6 billion 123 years 33 years 14 years 13 years 12 years

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 50.16 Lowest B.R. - Japan 8.1
Canada
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. - Swaziland 30.35
Lowest D.R. - United Arab Emirates Canada
11
Demographic Terminology
Natural Increase Rate: difference between Birth Rate and Death Rate of a country BR - DR = NI
12
Natural Increase Highest N.I - Niger 50.16 Lowest N.I. - Japan 8.1
13
Demographic Terminology
Immigration Rate: # of people who permanently move to a country Emigration Rate: # of people who permanently move from a country
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
Lowest P.G. - Trinidad & Tobago % Canada % Highest P.G. - Liberia 4.836%
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 (3 dependent people for every 10 working) Canada - 4.4
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 of year X 1000
19
Infant Mortality Rate Highest I.M.R. - Angola 192.5
Lowest I.M.R. - Japan 3.28 Canada
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 82.1 Lowest L.E. - Swaziland 32
Canada
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. - Mali 7.38 Lowest F.R. - Macau - 1.03
Canada
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
