Population Trend
How the total population has changed over the decades. A rising line means the country has been growing, a flat or falling line indicates stagnation or decline.
Population Projection to 2100
Estimated future population based on current trends in birth rates, death rates, and migration. The dashed line shows this is a projection, not actual data.
Birth Rate vs Death Rate
Birth rate (green) vs. death rate (red) per 1,000 people per year. When the birth rate is higher than the death rate, the population grows naturally.
Life Expectancy (Male vs Female)
Average number of years a newborn can expect to live. Blue shows men, red shows women. Women typically live longer in most countries.
Fertility Rate Trend
Total Fertility Rate — the average number of children per woman. A rate of about 2.1 is needed to maintain the population without immigration.
Population Pyramid
Shows the age distribution of the population. Blue bars (left) represent men, red bars (right) represent women. A wide base means a young population, a wide top means an aging population.
