World Population Clock
A live estimate of world population, births, deaths and growth, animated from cited annual figures — not a real-time measurement. Every counter links to its source, base year and method via the ⓘ next to it.
Population — today and this year

Explore a country
Pick a country for a live population estimate plus the numbers behind it — growth, how long it would take to double or halve at today's rate, its projected 2050 total, share of the world, density, urbanisation and age structure. All figures interpolate cited World Bank annual data.
Population by country
A live population estimate for every country, largest first. Countries with a detail page are linked; type to filter the list.

Counters animate real annual figures per second; they are estimates, not live measurements. Population, births and deaths interpolate from the latest annual growth rate; "today" and "this year" figures reset at your local midnight and January 1 and count up from zero. Environment and economy figures spread the latest annual total evenly across the year.
