How to approach this question
A population pyramid has males on the left and females on the right. For each age group in the female data table, draw a horizontal bar on the right-hand side of the pyramid. The length of the bar should correspond to the population value on the horizontal axis.
Full Answer
The right-hand side of the population pyramid should be completed with bars corresponding to the female population data:
- 0 to 9: bar extends to 3200
- 10 to 19: bar extends to 3300
- 20 to 29: bar extends to 3000
- 30 to 39: bar extends to 1800
- 40 to 49: bar extends to 1100
- 50 to 59: bar extends to 800
- 60 to 69: bar extends to 500
- 70 +: bar extends to 300
A population pyramid is a pair of back-to-back bar charts, with one side for males and the other for females. The vertical axis shows age groups, and the horizontal axis shows the population number.
The question asks to complete the pyramid for the female population using the provided table.
For each age group, you draw a bar on the right-hand side (the female side) starting from the centre line and extending outwards. The length of the bar is determined by the population for that age group.
- **0 to 9:** The population is 3200, so the bar extends to the 3200 mark on the horizontal axis.
- **10 to 19:** The population is 3300, so the bar extends to the 3300 mark.
- **20 to 29:** The population is 3000, so the bar extends to the 3000 mark.
...and so on for all the age groups in the table.
Common mistakes
✗ Drawing the bars on the wrong side (the male side).
✗ Drawing the bars with incorrect lengths.
✗ Drawing a different type of chart.
