📊 Understanding the Population Difference Chart
This visualization shows where and by how much the populations differ between Australia and New Zealand for each age group, split by gender:
Left Side (Males)
Blue = Australia has more males
Green = New Zealand has more males
Right Side (Females)
Pink = Australia has more females
Orange = New Zealand has more females
💡 How to Read: Each age group shows up to 2 bars - one on the left (male difference) and one on the right (female difference). The bar's color tells you which country has more people, and the bar's length shows by how much. For example, if you see a green bar on the left, it means New Zealand has more males in that age group.
