notes-
Population pyramid-
• Helps human geographers determine what's going to happen to a countries population
• Graphically represent the age and gender distribution of a certain population
○ Can be represented by a region or country
• Elements of population pyramid-
○ Age- young on bottom, old on top
○ Gender- male on left, female on right
○ Young and old populations- % of population under age 15- 30%; in Europe 17%, in Africa 42%
○ A high number indicates a great potential for future growth
○ If lots of people over age of 65, identifies need for health care and other social services
○ Life expectancy- an average number of year a person is expected to live; affected by many factors
