📊 Understanding the Population Difference Chart
This visualization shows where and by how much the populations differ between United States and Saudi Arabia for each age group, split by gender:
Left Side (Males)
Blue = United States has more males

Note: Dependency ratios represent the number of dependents (youth + elderly) per 100 working-age individuals. Higher ratios indicate greater economic burden on the working population.
Note: The replacement fertility rate of 2.1 is the level at which a population exactly replaces itself from one generation to the next.Both countries are experiencing demographic transitions as they develop economically. Countries below 2.1 face potential population decline without immigration, while those above 2.1 continue growing naturally.
