Age-sex pyramid

About this topic

The age-sex pyramid is a demographic chart that shows the age structure of an area together with the balance of males and females at each age. It is built from Census age and sex data and helps reveal whether a population is younger, older, or evenly spread across life stages.

The overall shape can indicate settlement history, ageing, and the presence of children, families, or retirees. It should be interpreted with household and dwelling data, because the chart is a visual summary of population structure rather than a standalone Census question.

Interpretation notes

  • This chart is assembled from age and sex data, so it is a visual summary rather than a standalone Census variable.
  • Read the overall shape first; use five year age groups when exact counts or narrower cohort comparisons are needed.
