Demographic Analysis: Singapore vs Bangladesh
In 2025, Singapore has a population of 6M, while Bangladesh has 176M. This represents a difference of 170M, with Bangladesh having 29.9 times the population of the other. Singapore ranks #113 globally by population size, while Bangladesh ranks #8.
The median age reveals significant demographic differences: Singapore has a median age of 37.4 years, compared to 27.0 years in Bangladesh. This 10.4-year difference indicates that Singapore has a significantly older population, with important implications for workforce dynamics, healthcare needs, and economic development. The dependency ratio in Singapore is 35.0%, while in Bangladesh it is 52.2%, showing the relative burden of non-working age populations on the workforce.
Gender balance differs between the two countries: Singapore has a sex ratio of 106.83 males per female, while Bangladesh has 96.69. Singapore shows a higher proportion of males, which can affect marriage markets, labor force composition, and social dynamics. These ratios reflect various factors including sex-selective practices, differential mortality rates, and migration patterns.

📊 Understanding the Population Difference Chart
This visualization shows where and by how much the populations differ between Singapore and Bangladesh for each age group, split by gender:
Left Side (Males)
Blue = Singapore has more males
Green = Bangladesh has more males
Right Side (Females)
Pink = Singapore has more females
Orange = Bangladesh 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 Bangladesh 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.
Historic Milestone: 2023
Bangladesh became the world's most populous country, ending Singapore's centuries-long reign
