Population Pyramids How to analyze
Population pyramids give lots of information • Total population of a country • Broken down in age groups of 4 years ( cohort groups) i. e. age 0 -4, 5 -9, 10 -14, 15 -19 etc… • Divides population by gender • Shows average life expectancy • Shows how many die in each age group
Canada Population Pyramid for 2005 Age and sex distribution for the year 2005:
Types of Pyramids • Different countries will have different shaped pyramids. • The pyramids are different due to the different standards of living each country has.
Early Expanding ( country) rd 3 world
Early Expanding Characteristics • Poverty an extreme challenge • Many babies dying early ( lack of proper food, medical attention, poor hygiene, polluted water) • Many births, but many dying as well. • Top of pyramid very narrow…low life expectancy • Struggle to survive day to day. • Note: Pointy peak, wide bottom, classic pyramid shape
Expanding
Expanding Characteristics • Poverty still a challenge, but not as bad as early expanding. • Births still high, but not as high. • Living standards are improving. • Proper diet still lacking, but better than early expanding. • Note: still has a classic- pyramid shape
Stable
Stable Characteristics • Birth rates dropping off…bottom is narrower. • Poverty for many, but a middle-class is developing. • Food supply is adequate • Healthcare improving • Life-expectancy is getting higher • Note: Pyramid-shape is shifting to more rectangular- shape.
Contracting ( 1 st world country)
Contracting Characteristics • • Income evenly distributed…strong economy. Healthcare is available to all and is modernized. Food supply stable. Life-expectancy is high. Birth-rate almost the same as death-rate. (= zero population growth) Note: Pyramid shape is almost more a rectangle
