9. Population Pyramid A quick way to determine population characteristics and some change over time A type of graph that demonstrates population patterns by age and sex –Cohorts = age groups or categories –Male and female % of total population shown –Describe the shape of the base, middle and tip for 1961 and 2006? What does a PP not show (or tell you)?
