Chapter 27.5, Problem 4CYL
Summary Introduction
To sketch:
The age structure diagram and also describe how their shape predicts future changes in the
Introduction:
The age structure diagrams are the ones that depict the age groups on vertical axis and on the horizontal axis; there is percentage of individuals in every age group. In this the females and males are depicted on opposite sides.
