Where the two pyramids differ

The pyramids are overlaid so you can read the difference by age and sex: the longer bar in each band marks the country with more people of that age.

📊 Understanding the Population Difference Chart

This visualization shows where and by how much the populations differ between United States and Argentina for each age group, split by gender:

Left Side (Males)

Blue = United States has more males

Green = Argentina has more males

Right Side (Females)

Pink = United States has more females

Orange = Argentina 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 Argentina has more males in that age group.
