📊 Understanding the Population Difference Chart
This visualization shows where and by how much the populations differ between United Kingdom and India for each age group, split by gender:
Left Side (Males)
Blue = United Kingdom has more males
Green = India has more males
Right Side (Females)
Pink = United Kingdom has more females
Orange = India 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 India has more males in that age group.

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.
