Population & Health Rankings
How many people, how long they live, and how fast populations are changing. These rankings cover the human story behind the numbers. Compare life expectancy, population density, median age, and more.
Countries by median age
Did you know the median age in some African nations is under 20, while in parts of Europe it tops 45? That 25-year gap will define economic competition and geopolitical power for decades to come.
Countries by population density
Did you know Bangladesh is more densely packed than almost any country on Earth, despite having no megacity that dominates its population? Density shapes housing, infrastructure, and quality of life in ways most people don't consider.
Countries by population growth rate
South Sudan’s population is growing at 5.86% per year—while Saint Martin is shrinking at -5.40%. That’s a staggering 11.26 percentage-point swing, meaning one country could double its population in just over a decade while another rapidly empties out. Few metrics capture global divergence as sharply as population growth.
Countries by population
Did you know India recently overtook China as the world's most populous nation, ending a six-decade streak? The demographic balance of power is changing — and the ripple effects will be enormous.

South Korea (rank 215, 4.5) and Macao SAR, China (rank 214, 5.5) sit just above Hong Kong, forming a cluster of the world's lowest birth rates.
Countries by Death rate, crude (per 1,000 people)
Monaco ranks 1st with a crude death rate of 20.97 per 1,000 people, more than 22 times higher than Qatar at the bottom of the ranking with 0.93. The gap between these two extremes reflects differences in population age structure, demographic composition, and underlying health conditions rather than a simple measure of mortality risk. This ranking covers 216 countries using 2023 World Bank data.
Countries by Mortality rate, infant, female (per 1,000 live births)
South Sudan ranks first with a female infant mortality rate of 66.8 per 1,000 live births in 2023, the highest among 196 countries measured. At the other end, San Marino records 1.3, producing a gap of 65.5 units between the extremes. The spread across this ranking reflects the wide variation in survival conditions for female infants in the first year of life.
Countries by Mortality rate, infant (per 1,000 live births)
South Sudan ranks 1st with an infant mortality rate of 72.6 deaths per 1,000 live births, the highest recorded across all 196 countries in this dataset. At the opposite end, San Marino ranks 196th with a rate of just 1.4, a gap of 71.2 per 1,000 live births. That 5,086% spread between the highest and lowest values illustrates how unevenly child survival outcomes are distributed globally.
Countries by Mortality rate, infant, male (per 1,000 live births)
South Sudan ranks first with a male infant mortality rate of 78.3 per 1,000 live births, the highest among 196 countries measured in 2023. At the opposite end, San Marino records 1.5, making the gap between first and last place more than 76 points. This spread underscores the extreme divergence in early survival outcomes for male infants across different parts of the world.
Countries by Life expectancy at birth, female (years)
Monaco ranks 1st globally for female life expectancy at birth, with newborn girls expected to live 88.5 years under 2023 mortality conditions. At the other end, Nigeria ranks 216th at 54.7 years — a gap of nearly 34 years between the top and bottom. The spread across all 216 countries reflects how widely female survival outcomes vary by geography and development level.
Countries by Life expectancy at birth, total (years)
Monaco ranks first for life expectancy at birth with 86.37 years, based on 2023 World Bank data covering 216 countries. At the other end, Nigeria ranks 216th at 54.46 years, a gap of nearly 32 years between the highest and lowest values. This spread illustrates the wide variation in mortality conditions across the world.
Countries by Life expectancy at birth, male (years)
Monaco ranks first globally for male life expectancy at birth, with newborn males projected to live 84.45 years under 2023 mortality conditions. At the other end, Chad ranks 216th at 53.20 years, a gap of more than 31 years between the top and bottom. That 31-year spread across 216 countries reflects the wide variation in mortality patterns recorded in this dataset.
