Study Notes
Biological Structure of Populations
- Populations are divided into three age groups: young (0-14), adults (15-64), and elders (65-00)
Population Pyramids
- A population pyramid is a chart showing the age and sex of a population at a specific time and place.
- It's a combination of two charts (one for males and one for females), sharing a common axis.
- The vertical axis represents age groups (typically 5-year intervals).
- The left axis represents males and the right axis represents females.
- The number of males and females in each age group is shown in absolute values (e.g., thousands or millions) or relative values (e.g., percentages).
